Why wait for a Canon 40D?

Go to last post
you try to compare l17-55mm f2.8 on 20d and what lens on 5d ??
no no...

this lens would be 28-80mm f4.5 , it would be very cheap lens but will give you same result like 17-55mm f2.8 on 20d.

same FOV , DOF , and you dont louse the stop becouse you have less noise with FF senzor..

all best

The introductory price of the upcoming 40D (body only) will
probably be $1400, based on the 30D's price upon release. It'll be
10 Megapixels, since it's highly unlikely Canon will abandon its
1-month old 10 MP sensor so soon.

Meanwhile, the Canon 5D can be had for around $2050 after the
rebate these days. Its full frame sensor, 12.8 MP images, and high
ISO performance is unlikely to be surpassed by the 30D series until
at least 2 (probably 3) generations down the road. And the Canon
5D usually doesn't need a dedicated wide angle lens, since there
are a host of normal zoom lenses that go as wide as 24mm. A 30/40D
camera, on the other hand, would require a seprate lens for decent
wide angle, which factors into the cost of the body. A Canon 40D
with EF-S 10-22mm would cost more than a Canon 5D.

So for people who aren't into action photography (5 fps) or
wildlife (long telephoto)... does it make sense to be waiting for a
Canon 40D at this point?

Just speculating: I think the 10MP sensor used in the 400D will be fully amortized over the 20 kajillion units they will sell by the end of the year. That may be the end of the line for the current sensor technology.

There may be some significantly innovative sensor technology that we will begin to see next year, and 40D may be the first camera we will see it on (along with a roughly-PMA 1 series release, perhaps?) The rumors are increased DR and lower noise. I have no idea of the specifics; it just seems that Canon have been doing kaizen on the same basic sensor technology for quite some time now. I'd say just on that bases we are due for the release of some breakthrough technology.

Well, as I say, it's just speculation, but such a next gen sensor would definitely be something worth waiting for.

Onof 1.6 crp advantage is on the long end. My 70-200/2.8 becaomes a 112 to 320/2.8. My 100-400 becomes a 160-640. It will cost you some coin to get that range on a FF.

Let's see, Canon 5D, $2050, 16-35, $1400. As George HW Bush would
say, voodoo economics. Since I got my 17-55/2.8, which by the way
is sharper than my three L lenses, my 10-22 has been gathering dust.

24mm and 28mm are very popular for wide angle photography. Ever
notice how many different companies make prime lenses in both 24mm
and 28mm? It's a big deal for landscape and architecture
photography.

One of full frame's advantage over cropped sensors is that 24-xx
zoom lenses on FF are often wide enough to cover the most popular
focal lengths in a single lens --- 24mm, 28mm, and 35mm, and 50mm.
Hence you won't need to buy the ultra wide angle 16-35L or 17-40L.
There's a decent number of 24-xx zoom lenses available to choose
from.

On a 1.6x crop sensor, there are no good normal zoom lenses that
give you the 24mm equivalent. You would need to buy a separate
ultra wide angle zoom lens (like EF-S 10-22mm) if you want the 24mm
equivalent. All the EF-S normal zoom lenses start at 17mm, which
covers 28mm but not 24mm.

the 12MP sensor takes longer to get rolled into the spool.

Is this double $300 rebate speculation or has it been announced?

No, that's not my middle finger....
 
Well, not exactly, but quite close, .purely based on little I know, so may have this backwords but my math is as follows

1.6x crop of a 12.8 MP Camear = 12.8/1.6, you guessed it 8MP

So instead of a smaller sensor on 30D, you can manually crop the photo yourself and get the exact (almost) same range. A 200mm lens on full frame 5D, cropped by 1.6 factor in post processing should theoratically give you the same effective 320mm. (ok, since you loose .2MP, it would be closer to 313mm).

My guess is that the next revision of 5D, using the new sensor would be
16.1 MP (10.1*1.6)

I don't know if I ever really want to go FF. One of my main
reasons for getting a 20D was to shoot better sports pics of my
kids. For sports, my main need is length, not wide angle. So, my
70-200 2.8 really goes out to 320. On a 5D, I'd have to get the
300 2.8 to get that same coverage. No thanks, price wise.

The correct number is actually 12.8/(1.6*1.6) = 5mp

To loose the crop advantage you need a FF camera with the same pixel density as the 1.6x camera. That means a 20.99mp FF camera to match the 30D.
 
i will wait and hope the 40D has a quiet shutter.... banging two tin cans every time i take a shot is not my idea of discreet. I will hold onto my D30 until then.

well, unless they stick a pop-up flash onto the 5D (perhaps its good they didnt or i would be crying over the lost mortgage payment)..

and yes, i have external flash units, but i dont want to carry them all the time for fill flash in daylight.

the finer line of upgrading for an extra MP or so is totally lost on me...
 
That they gave the "real" upgrade to the 400D instead of the 1 series? It's trickle UP tech this time, not trickle DOWN.

I just hope the next gen of upper level cams have real "WOW-factor" upgrades.

peace.
 
I'm thinking (and hoping) the 40D will have a 1.3 Crop Factor.

Using the same pixel density as the 30D, this will result in 8.2*(1.3²) =13.8 Megapixels. That's the MINIMUM to expect if they go to a 1.3X sensor.

That's the easiest way for Canon to make a big improvement. Cramming even more pixels into and APS-C sensor without degradation is starting to become too difficult I think.

Maybe they'll even use the XTi's density and give 10.1*(1.3²)= 16.9 Megapixels - but I doubt they will if (as it seems) the 400D sensor is less sensitive and a little more noisy than the 30D's.

I've purchased the XTi to keep me busy until then! :)
 
If there is a 40D, it will not be a 1.3 crop factor. Feel free when the 40D is announced (if there ever is one) to pull this post back up and show me I was wrong, lol! If there is a 40D, it will be the next camera in the D30/D60/10D/20D/30D line of cameras, all 1.6 crops. A 1.3 crop camera in this price range would start a new line of 1.3 crop cameras. I promise you, if you are waiting for the 40D to get a 1.3 crop camera, you will be disappointed.

A 1.6x crop of a 12 megapixel image is about 8 megapixels, which is what you get from the 30D.

Nobody knows right now - depends on how this is implemented, if it
is ever made available.

'elegance is simplicity'
 
Maybe so - but they won't get many 40D sales if all they do is stick the 400D sensor and dust cleaner into a 30D body. Their new 10MP sensor is already less sensitive and noisier than their 8.2 MP sensor introduced with the 20D long ago.
Would you buy it?

Unless they develop a whole new sensor technology (HDR?) it looks to me like they are about to hit a wall.
So now they are up against the wall!

I don't think they would hesitate to change the XXD line to 1.3X if it means a camera that will sell vs. one that won't.

So then we'd have:
XXXD = 1.6X
XXD becomes 1.3X
XD = 1X

Nice and simple!

Like I said I'm not holding my breath over it - I bought the XTi.

Even if they REALLY disappoint me next year, the 30D and 5D prices will keep on dropping...I'll get satisfaction somehow!
 
Haven't you heard about the ultra-enhanced dustbuster the 40D will have? http://forums.dpreview.com/forums/read.asp?forum=1019&message=20234260

Seriously, though...the 40D, when it comes out around the end of next year, will be a good buy specifically because it's going to be competing with the used 5D. That, and if you recall, they introduced the 5D and 30D at the same time, which means that the 6D will probably come out around the same time as the 40D. So, the deicision won't be, should I buy a 5D or a 40D, it'll be, should I buy a 40D or a 6D.

Besides, if they do the same thing they did with the XTi, the 40D will be introduced at a lower introductory price than the 30D was, putting more distance between the two models than you're currently thinking about (then again, by next year the 5D will probably be going for $1500, so...).

Good reasons to pick the 40D over the 5D/6D, though...

1. Investment in EF-S lenses. I already have 2 EF-S lenses. I'm not upgrading to FF until they come out with something in the same price bracket that replaces the 10-22 and the 17-85.

2. Price. You're saying right now there's a $600 or so difference between the 30D and the 5D. That's a lens right there, or most of one anyway.

3. Zoom. I might like my lenses getting the 1.6x boost. With the extra resolution and the DiG!C III, maybe I'm not so concerned about the smaller sensor.

None of this means that the 5D is a lesser camera though. Just that it's aimed at a different niche of the market...wide-angle shooters that have the money to spend on top-quality EF glass.
