Sharpness - Doesn't Add Up

Also, you look past the actual message of the OP. It is not really "Canon et al. should make more P & S-like DSLRs", it is "This particular model of DSLR should be more like a P & S".
As the "OP" :), I must have been unclear for you to take that interpretation.

My statement was "if a point and shoot can take a sharp image without post processing, then there should be a setting on the Rebel XT and 20D that would achieve at this – setting the sharpness to +2 doesn’t accomplish this."

In the interest of not debating preferences for sharpening, please feel free to replace "sharp" above with "way too sharpened like a P&S" -- it won't offend me. I tried +2 on the 20D and couldn't achieve that overly sharpend P&S look. I AM NOT saying remove parameter settings +1, 0, -1, or -2!!!

I recently shot 600+ pictures on a trip to Paris with a P&S. I'm not trying to send my pictures for display at the Louvre :). In fact, most will simply be posted to the web as a reminder of the trip and get posted straight to the web. For these I like the (overly) sharpened look of the P&S. Problem is, that I also want control over DOF, better high ISO performance, and other lens. Simply being able to have the option** of P&S sharpness would bridge the dual-purpose gap.
This is incorrect, since from everyone's point of view the situation is fantastic: Canon's, the consumer's, and the reviewers'. Just about the only people that hate the 350XT are cross-posters from the Nikon part of the site.
This reminds me of people at a company were I did consulting. The comany was number in their field and rightly so -- awesome products. Funny part was everyone from shipping, accounting, information tech, to product development thought because of the companies success it must be because their department was making all the right decisions. In this case, the product development and marketing were top notch. Other deparments had some real problems but refused to acknowledge any areas for improvement because the company as a whole was number one. Are the 350D and 20D flawless?
However, you can't say that all cameras that aren't P & S-like are hunks of junk.
Huh? Where did you get this from my post??? A P&S doesn't have DOF control, lens interchangability, low noise at high ISO, and on and on.
You also can't (believably) lament the failure of a particular camera to be P & S-like when the intent is obviously to bash.
Bash, no. Frustration, yes. Returning a camera is a PITA.
 
If you camera does not function properly get it repaired.

There are plenty of happy users that have no problems with AF.

What other problems you refer here?
Its a simple fact that the 350d is a flawed camera with focusing
and other problems. But you cannot say that here because you will
be shot down like a space invader. The sooner Canon admit the
better it would be for struggling photographers.

I'm not sure what the problem was. Shots from the camera at +2 should look very sharp(ened).

If you want a valid thing to ding Canon for, I'd suggest complaining about the kit lens, and even the overpriced 17-85IS. These lenses just aren't that sharp at many focal lengths.

Jeff,

After looking at your many hit and run posts, as well as your lack of experience, I shouldn't have take the time to respond. From your 28 May post 1 1/2 months ago:
We'd love any tips whatsoever, as we're both photography newbies!
(I also try to get EVERYTHING in focus all the time, which is probably another newbie trait, but I like detail!)
It is great news that you like your camera. Take lots of awesome baby pictures, congrats! You're obviously like to read and compare camera stats, but please drop the sarcasm (just saw your post to me "Ban this Troll") and share your experiences as you call yourself "a newbie" -- 1 1/2 months doesn't turn you into an expert.

If someone has the money and wants an EOS 1Ds they should be able to P&S if they want, but that is not what I am saying. The option should be there for people. Most of my customers are still in the "What kind of film does it need?" phase and those are the people that should be able to P&S and get a better shot than a Kodak P&S camera. Thats my point. A digital SLR should outperform a P&S digicam and not have to say "A DSLR isn't for you".

Actually as funny as it sounds, there is a custom function on the D70/D70s that adds lines to the viewfinder so you will know where it crops when shooting an 8x10 so I suppose it could be used for this purpose also. :)

Mark,
Just think about what you are saying:
"if a point and shoot can take a sharp image without post processing, then there should be a setting on the > Rebel XT and 20D that would achieve at this – setting the sharpness to +2 doesn’t accomplish this."
In other words: you want Canon to add a gimmick that allows you to get bad pictures without effort. Well, I hope Canon doesn't listen - but being people what they are, I am not so sure!

It is as if you bought a Ferrari, and are complaining that it is not as comfortable as your old Samsung to go shopping.

BTW, I have nothing against the other makes: I hope that they keep in business making great cameras, as it happens now. That is the only way for things to go on improving.

I've read through this entire thread and have several comments based solely on my experience with three 20d cameras.

After reading reviews on this site and others, and having previously owned a Canon Rebel 2000 (300) 35 mm SLR, I decided to purchase a Canon dSLR. The hardest choice was between a Rebel XT and the 20d. I decided on the 20d.

The first 20d I got could not take a sharp picture. I used it with both the 18-55 EFS kit lens, and a Vivitar 28-200 series 1 zoom that I had from my 35 mm camera. Not a single picture looked good, pictures with the flash looked even worse. I also called Canon, and their technical support stated that in the green dot mode it should take better pictures. I exchanged the camera for a second camera.

The second camera was only slightly better. Again Canon said the camera should work better, and they didn't rule out two defective cameras.

I then exchanged the second 20d. Bottom line, the third camera was obviously from a later production run. It had a totally different serial number, and had a later version of firmware (I don't think it was the firmware, only pointing out a later production run). The third camera was MUCH better than the other two. The first two were obviously defective. The third camera was capable of some very good pictures.

However, some of what I attributed to the first two was just the way the 20d works. I do believe that at least when not in the creative zone modes, the camera should work more like a typical camera. It already uses more agressive processing parameters. Basically, I consider the auto modes (at least the green dot) almost unusable.

I am not a novice photographer. I've been using 35 mm SLRs since about 1973. My most recent was a Canon Rebel 2000. That camera, with the 28-200 Vivitar Series 1 lens has taken many beautiful pictures. For snap shot, or fast shots, I can just put the Rebel 2000 in it's green dot or P mode, and shoot. Almost every time I would end up with at least an acceptable picture, and usually a near perfect one. Yes, other times I did use the creative zones, but never felt I HAD to.

If I shoot the same way on the 20d, with even the same lens, I get much worse results. I very quickly learned that unless I was very close, with a lot of ambient light, the flash was useless in the green dot mode. I very quickly started using the creative zones, at least P and bumped the flash exposure up about 1 to 1.5 stops. This helped significantly. I did need to review the histogram to make sure it was not overexposed, look for flashing areas, etc. Further away it gets even worse.

Compared to the built in flash in the Rebel 2000 it has been much worse. I believe this is a very reasonable comparison, and I believe the 20d should work as well, or better. All the hype over ETTL II, and what I get out of the camera is junk unless I manually tweak the exposure.

As far as sharpness, I also tend to agree with the thought that the camera should be sharper.

I knew that the Vivitar lens wasn't the best lens in the world, but like I previously said, I have taken some excellent 35 mm pictures with it.

So, within a week of having the 3rd 20d I ordered some lenses. I bought a Sigma 18-200 f3.5-6.3 DC series zoom, and a Canon 50 mm f1.8 mm prime lens. This is in addition to the 18-55mm kit lens, and the 28-200 Vivitar.

I will admit that with enough tweaking, I have been able to get some truly beautiful pictures out of the 20d, with several combinations of lenses. Still, I needed to sharpen them, tweak exposure and levels in Photoshop CS.

I did print both processed and original out of the camera versions of 4 x 6 prints at BOTH Costco and WalMart! While the out of camera pictures are acceptable in most cases, the difference in sharpness is visible even on a 4 x6. I did not get very aggressive. I used a 1 pixel radius and about 99 - 120 sharpening. I also printed pictures on a Canon I-950 photo printer with even more pronounced difference that the Costco or WalMart, even with a 4x6.

Many of the pictures also come out quite dark and murky. Many of them have enough dynamic range that they can be tweaked in photoshop. Others however are reallly beyond the range of reasonable correction and still getting a good picture.

Pictures with the internal flash are especially poor.

I do believe that at least in the green dot fully automatic mode, the camera should work pretty much like a P&S. It should at least be sharp, focused, and properly exposed, with or without a flash. Not only is this a reasonable expectation, it is what I experience with a Canon Rebel 2000 35 mm camera.

There is no excuse for the internal flash working so poorly. Again, I'm not expecting miracles, but if a take a picture 6 to 10 feet away, I expect a reasonable exposure.

Canon already has a creative zone, an image zone, and full auto. I fully believe that I should be able to put the camera in the green dot full auto mode, and get a picture as good, or better than a P&S.

I am not Canon bashing. I thought enough of my Rebel 2000 to buy another Canon. Even after 2 defective 20ds I stuck with it. I had very serious doubts after the second defective camera. Should I go with the Rebel XT, or even the Nikon D70? I stuck with Canon. After using the camera for a about a month and a half, I LOVE the way it operates. While I have a few gripes about the small dim display, overall I simply love using the camera. It's like shooting with a film SLR. The shutter delay and poor electronic or optical viewfinders are gone.

While I fully expect to run most pictures through a computer, I shouldn't NEED to. The camera does support PictBridge, this would imply that you can print right from the camera. My experience is that you will not get optimal results that way.

Conversely, the pictures from my Fuji Finepix 3800 are near perfect right out of the camera.
 
I spent an afternoon shooting with both my 20D and my SD500 (P&S) in my bag. For the sake of comparison, I took many shots that were nearly the same with both cameras.

On the 20D, I was using mostly the 17-35L and Sigma 18-125 (also for comparison).

I shot the SD500 in low sharpening and the 20D in parameter 2, which is alos lowish sharpening. In terms of exposure, both cameras performed in an exemplary manner, with little or no perceptible difference between them.

The 17-35L focused perfectly, but just isn't a very sharp lens. The 18-125 did miss the focus by a significant amount about 10% of the time, but when it focused properly, it was sharper than the 17-35L. The SD500 nailed the focus every time.

In terms of sharpness and detail, I found them to be quite similar, with the exception that SD500 was losing some detail in darker areas due to noise.

I've found that with a good lens, my digital SLRs produce shots that are wonderfully sharp. I couldn't hope for anything more - except perhaps more consistent focusing from my 20D. (BTW, this isn't a comment about the 18-125, which I realize is not Canon's problem; it's a comment about my 20D slightly misfocusing with nearly all of my lenses about 10% of the time.)

Here's a shot from my old D60, straight from the camera, all settings at the default values, taken with the 50mm 1.8. The DOF is quite shallow, but you can zoom in and count the number of pixels spanned by individual hairs that are within DOF. If you do this, you'll see that some occupy essentially a single pixel width, with some fade off into adjacent pixels. This is the best one could possible expect from a Bayer pattern sensor.

I think the perception that DSLRs somehow don't produce sharp or properly exposed images comes from a combination of:
  • Poor quality control
  • Low quality kit lenses
  • Unreasonable expectations

I can't comment on your experience with focus and the built in flash, but when it comes to pictures right out of the camera I think I can.

In the film days, we would chose a film that we liked. All films have an s-shaped contrast curve, which differs quite a lot between different films. Some films are more neutral, and some have more punch. In combination with a photo paper, you get a characteristic look. Digital cameras have a linear contrast "curve", which makes the images look washed out. This is true for all cameras without any manipulation.

I think it would probably be a good idea to make film simulators that people could use to apply curves right in the camera, but there would also be problems with this. First, you would need a pretty complex computer program and more processing power. You would need many more parameters to adjust. Also, the images produced (if you use jpeg) would be damaged beyond repair if you didn't get the exposure just right. You would deliberately limit the tonal range. It would be like shooting with slide film, which is quite limiting if you can't bracket your exposures.

While I think having the option of simulating films could be a good thing, I don't think it's realistic right now (we need pretty clever computers). It would be too expensive, and probably ruin more than it helps. A point and shoot camera can't stand as much post processing as a dSLR, and quite frankly the ones I have tried doesn't make perfekt pictures anyway. You still need to touch them up a little with curves, and then the internal processing just degrades quality.
 
I'm still confuased as to why people buy a $1,300 camera and put it on full out or P mode?!?!?!
 
There are several reasons why someone would use the green dot or P modes.

The most common one for me is when I hand the camera to someone to take a group picture with me in it.

Moreover, because I am capable of manual modes, it doesn't mean that I use them all the time. I do expect the auto modes to work as well as a less expensive camera.

There are many times I use either shutter or aperature priority to optimize DOF, or if I am shooting with a telephoto and want to minimize blur from movement. Like I said in my original post, I am not a novice. I used a fully manual Minolta SR-T101 for over 20 years.

There are times though that I simply want to take a "snap shot." Many times my wife and kids are not patient even for a few seconds. "I hear just take the picture already, we need to go NOW...." The green dot is smart enough to pop up the flash, saving another 1 -2 seconds of pushing the button. Yup, that can be the difference between a picture and none. Speed is one of the reasons I bought a dSLR in the first place.

With my Rebel 2000 it worked this way. The Rebel body cost a whole lot less than the 20d. Yet the Rebel 2000 almost always gets focus and exposure right, even with the less than ideal Vivitar Series 1 28-200 lens.

When I bought the 20d, I originally planned on using the same Vivitar lens. I believed I was able to see more so much more detail as to point out the deficiencies of the lens. I'm not sure of that now. I've got pictures of a Mountain taken with a 50 mm f1.8 Canon prime lens with the camera on a tripod that the camera didn't get focus correct.

Again, I'm not bashing the 20d. I REALLY like it. It's not perfect though. I think it is real very fair to compare it to a Canon 35 mm SLR that cost MUCH less. It was my experience with the Rebel 2000 that made me a Canon fan after many years of using Minolta.

The arguments of the sensor size may or may not be valid against P&S digicams, but that argument is clearly flawed compared to 35 mm film. The image size is larger, not smaller. Given a full frame lens, the 20d should work better as it is in the "sweet spot" of the lens.

I have been using semi-manual modes with the 20d, almost because I have to in order to get a reasonable picture out of it. I don't think that is reasonable at all. I've also shown the pictures I took with it to friends that have a 10d, D60, and the original Digital Rebel 300. All of them thought something was wrong with the camera.

If I put the camera in full auto mode and aim it at a subjectr 6 to 8 feet away, it should work. What I get, especially with the flash are dark, muddy pictures that even PS can't correct. They are so dark that if you tweak the levels enough to get it looking right, there is way to much noise. I hope the camera isn't defective. I exchanged it twice and am on the third camera, and out of the exchange period. This one does work much better than the first two.

I've learned to compensate, but I shouldn't have to. My Fuji Finepix 3800, and my Rebel 2000 are most definitely far more reliable in getting proper exposure. The Rebel 2000 is also much better at reliable focus, the Fuji sometimes has problems in low light with focus but otherwise is also very good.

Bottom line, I like the camera, actually a lot. The speed is amazing, it's really a pleasure to use. However I am dissapointed in focus, exposure, and sharpness. Those are pretty basic attributes of a camera after all.

Exposure problems? Good grief. You haven't used the Nikon D70 (exposure behavior varies from one lens to another) or Minolta D7D/Pentax DS (which under-exposes pics to preserve highlights) or the Oly E300 (read Phil's review) systems, have you? :) The Canon exposure system is actually pretty darn good. Some guy (Ricehigh) in Pentax actually did a comprehensive measurbating kind of testing and found the Canon exposure system to be very consistent and accurate.

Seems that what is good to one person may be awful to another. I am beginning to believe these forum discussions actually lead nowhere.
