On Nikon 1 J5: What you need to know article (493 comments in total)

I just bought a new Nikon V2 w/ 10-100mm lens kit for less than the going price of the 10-100mm lens alone, and have been favorably impressed with the V2's AF speed and accuracy, the controls layout, and handling. The compact, (2.38 in. or 60.5 mm long) ,10-100mm lens is surprising sharp for such a wide range of focal length, even at 100mm.

Looking at the photo results (shooting RAW and processing with Capture ND), this evening I was thinking that with a little more dynamic range I could easily give up my Nikon D7000 and all my large heavy FX and Dx lenses and just go all in with the light weight and compact Nikon 1 system. If the new sensor is as good as I think it will be with improved dynamic range, I predict more than a few will switch from DX to Nikon 1 in the future.

On Nikon D7200 First Impressions Review preview (1113 comments in total)
In reply to:

califleftyb: I bought the D7100 and found the images to be rather noisy. After looking at the sensor specs I saw why - the sensor's pixel pitch was one of the smallest of any Nikon camera, at 3.9µ similar to the D3200. In fact Nikon reduced the pixel pitch from the D7000 (from 4.8). I was rather shocked at this ploy to get "more megapixels" to induce more sales. I wish DPReview added this information to the specs when they do a review. I suggest anyone looking to upgrade to any Nikon camera look at this number carefully if it is an important issue to you.

I found the noise in the D7100 images annoying as well and not up to the cleaner images I had come to expect from my D7000. Needless to say I kept my D7000 and did not "upgrade" to the D7100. If IQ has not improved again with the D7200, I will be keeping my D7000 for a long time and investing in lenses instead.

On Not dead yet: Sony announces three A-mount lenses article (120 comments in total)

I had once owned the original Sony 70-300mm F4.5 – F5.6 G lens used on a Sony a700 and was impressed with it's sharpness excellent micro-contrast optics. However, I was disappointed with the focus speed and the thin plastic build which made the lens feel cheap. My lens became infested with grit of some kind due to a lack of sealing even though I was careful with it. In comparison my Nikon 70-300mm (paid $350 in a kit price), is not as sharp, and lacks great micro contrast, but the focus speed and build quality is superior to the Sony 70-300G. I have had the Nikon lens in all kinds of environments over the past four years including blowing sand and salt spray without any issues. Nice to see Sony realized the original 70-300mm F4.5 – F5.6 G shortcomings and have corrected the issues!

In reply to:

StefanD: Is it me, or are those leaves in the background of the sample picture under "Image Quality" plain ugly and very distracting?
I find that picture very unpleasant to look at.

I agree. That photo of the tree leaves is very disappointing in terms of sharpness (especially beyond the center), and the bokeh is terrible. I get better images from my Nikon V1 with just a 1" sensor. One can have a wonderful sensor in a camera, but a poor lens can ruin it all. Obviously Panasonic took too many shortcuts with the lens and it shows. Like they say, "A chain is only as good as it's weakest link."

On Panasonic Lumix DMC-LX100 Review preview (933 comments in total)

Well, darn it!
I really like the design concept of the LX-100, which is very close to what I want in a travel camera in terms of size and sensor image quality. However, it fails on on four counts that give me reason to pass on this camera.
1. No phase detection auto focusing. (Sorry, but I am spoiled by my Nikon V1's focusing performance!)
2. No built in flash, and the supplied flash is crude and weak with no bounce capability. At least the tiny flash for my Nikon V1 can do bounce flash.
3. Inferior EVF. There are much better available that do not tear.
4. Despite the hype, my eyes tell me the lens is not sharp enough, especially at the edges, which is a big disappointment considering the price of the camera and the short focal length range.

As it stands, the LX-100 is a bit too disappointing and over-priced for it's performance capabilities. Hopefully the rumored Nikon competitor to this camera will not have these shortcomings.

In reply to:

burnin: The Panasonic GX7 has a flash, hotshoe and viewfinder.
I wonder they left the flash out of the LX100. Big mistake.

I agree. Maybe not a deal killer, but no built in flash is a big disappointment to an otherwise near perfect camera of this type. I have been using a Nikon V1 which also does not have a built in flash and I have found it is a real pain in the rear putting the flash unit on and taking it off and stowing it away. I have dropped the fiddly flash unit and almost lost the darned thing a couple of times. There are many times I would use fill flash outdoors, but don't bother due to the hassle of putting the flash on. Oh well, at least the LX 100 includes the flash unit in the price and has an EVF which is more important to me than a built in flash.

Too bad there is no EVF. That's a deal killer for enthusiasts. Using a rear LCD to compose is lame, and especially annoying in sunny conditions!

On Samsung NX mini First Impressions Review preview (559 comments in total)
In reply to:

BG_CX3_DPREVIEW: There must be a market for these things,

Nikon keeps investing in their 1 series, now Samsung.

I don't get it really, The NX300 costs almost the same, with a18/55.

Probably a style exercise, a model to create as thin lenses as possible.

Now their engineers have a platform to try thsoe thin lenses, if it fails, than it is because of the mini, so the mini dies and the other cameras do not suffer from it.

Still i don't get it, there is absolutley no benfit whatsoever in using a 1 sensor over a 1/1.7.

Enough enthousiasts cameras in the same price range that perform just as good.

A 1 cannot create bokeh with these small and slow lenses anyhow.

"no benefit whatsoever in using a 1 sensor over a 1/1.7."
I disagree.
The 1" sensor in the V1 has greater dynamic range and better high ISO IQ than any of the dozen 1/1.7 sensor cameras I have owned, so I can't agree with you.
In fact the Nikon 1" sensors IQ is superior to the older DSLRs like the Nikon D40, but with better AF and much higher frame rate with video capability as well, all in a much smaller package. As an owner of APS-C DSLRS, I was skeptical of the the 1" sensor as well, at least until I actually purchased and used the Nikon V1.
I have been favorably impressed with the Nikon One image quality to the point that I now use it more than my DSLRs and I never use my drawer full of P&S cameras anymore. Different strokes for different folks!

On Samsung NX mini First Impressions Review preview (559 comments in total)

The Nikon One J1 with 10-30mm VR lens can be purchased for under $180 in the US, and the V1 with EVF for less than this Samsung as well , and (unlike the Samsung), both have fast and accurate on sensor phase detection auto focus capability for stills and video. The Nikon NI cameras also have a much larger and better native lens selection going out to 300mm (same FOV as 800mm on FX), and the ability to use Nikon FX and DX lenses in full auto mode with the FT-1 adapter. For these reasons, I don't see Samsung's 1" sensor cameras competing successfully with the Nikon 1 system cameras, (especially in the US where Samsung is only thought of as a television and appliance company.)

On Am I missing something here? article (626 comments in total)

Richard,
You missed the Nikkor 18.5mm f1.8 in your list of enthusiast lenses.
It's hard to take your opinions seriously Richard, when you don't even bother to vet your research before you go about bashing a camera system you don't use and know so little about.
You are missing something else Richard: Journalist objectivity.

I have been into photography long enough to remember when serious 35mm primes were expected to be f2.0. Making a sharp 35mm f2.8 prime is cheap and easy. Too bad Sony took the low road and made this consumer grade lens a full stop slower than the excellent Minolta 35mm f2.0 legacy lens of yesteryear, and adds insult to injury by pricing it like a pro f2.0 lens. I just don't see how Sony's new FE mount camera system will be successful without a full set of pro quality FE lenses, and in terms of maximum aperture, this lens does not qualify as such.

On Sony Alpha 7 Review preview (1608 comments in total)
In reply to:

Abhiru: I used to value dpreview information a lot, but this review struck me as strongly biased; there must be a VERY GOOD REASON for dpreview to risc their reputation in such a blatant way.

If anything DPR was too kind to the A7 in their review. In no way does this camera deserve even the Silver Award based on IQ, handling, AF, and performance, not to mention the pitiful FE lens offerings. Sony may someday produce an improved version of the A7 with some pro FE lenses to mount on it, but until they do, the FE line of cameras is merely a plaything for those fascinated with expensive mirrorless cameras, rather than a serious and competent photographer's tool.

On Sony Alpha 7 Review preview (1608 comments in total)

Based on the DPR review of the A7, it is obvious that Sony has overreached with their new line of full frame mirrorless FE cameras. which can not even match the capabilities of Nikon and Canon DSLRs introduced over a year ago.
If Sony still has any ambitions of taking FF market share away from Nikon and Canon after this fiasco , they will have to do a lot better than this feeble attempt of mediocre bodies and FE lens selection. Maybe Sony should instead stick with what they do best, whatever that may be.

In reply to:

Scottelly: Frankly, I think someone at Sony is on crack. They should have been ready at launch with a whole group of 9 or 10 lenses, including a kit zoom (like a 28-90mm f3.5-5.6), a premium zoom (like a 24-105mm f4), a long zoom (like a 100-300mm f4-5.6), a standard prime (like a 50mm f1.4), a premium wide prime (like a 35mm f1.4), a macro (like a 100mm f2.8), a portrait lens (like a 135mm f2), a premium long telephoto (like a 300mm f2.8), and a super-wide zoom (like a 15-24mm f2.8). Then they could go from there, offering a longer telephoto, like a 500mm f4 prime and a super wide prime, like a 14mm f2.8. Eventually they could make an 85mm f1.2 to compete with the Canon L flagship lens. ALL of the new lenses should be weather sealed, and they could all be very good quality and priced to beat Nikons and the Canon L lenses. You don't launch a new line of cameras with no lenses! It's not like they don't have the ability to make lenses or something! I don't think I'll ever understand Sony.

Using the existing Alpha mount lenses with the A-E mount means no image stabilization and very slow CDAF focusing with the A7R and probably the A7 as well, (assuming AF works well at all). It also remains to be seen if the A-E adapter will cut off UWA lenses or ruining the bokeh of large aperture lenses by clipping. There are a lot of unknowns for such an expensive camera. Hopefully the professional reviews will answer them.

In reply to:

wcan: Am I understanding this correctly...the A7 with phase detect autofocus does not focus as well as the A7r which does not have any phase detect AF? What is the speculation as to the reason for this?

Sony has struggled for years to perfect on-sensor PDAF and it appears they are still struggling! Wise buyers will wait for the reviews on the A7 PDAF accuracy and speed before buying!

On Sony Alpha A7 / A7R preview (2371 comments in total)

With the A7s alongside their a99 and RX1, it appears Sony is aiming to be the king of of full frame niche cameras using two different lens mounts four different lens adapters and two different flash shoe mounts . Unfortunately for Sony, it is very unlikely that these niche cameras with their pedestrian performance and image quality that can be found in the much more popular Nikon lens mount cameras will ever be sold in quantities large enough to make them profitable for them. The only question is, how long will they keep trying?

On Olympus PEN E-P5 Review preview (499 comments in total)
In reply to:

SHood: "shutter shock" is a problem with all mirrorless cameras. Smaller body is part of the problem but also due to the shutter requiring a close/open to start the exposure and then another close/open to end it. This quick double shutter action is different than DSLRs which just need to open to start the exposure and then close to end it.

I have found with my GH3 that shooting at hi-speed continuous shooting does help as liveview is disabled so you don't have the double shutter action except to start the first image and end the last image in the sequence. The electronic shutter on Panasonic bodies also helps but is limited.

The new 1/8000s shutter speed on the E-P5 and E-M1 has probably made it even worse as the shutter is now designed to move even faster. Only the global shutter will totally eradicate this.

I have never experienced shutter shock with my Nikon V1, so no, it is not a problem with all mirrorless cameras. Maybe Olympus just can't get good engineers since they are having financial problems?

On Olympus PEN E-P5 Review preview (499 comments in total)

A thousand dollar camera body and it doesn't come with a viewfinder? Really? So you have to buy the big ugly VF4 EVF separately for another $300 which makes the camera body $1300 and to top it off, it takes blurry pictures! Who in there right mind would buy the E-P5 when the OM-D E-M5 with an EVF and no blurry pictures can be had for around $900? With designs and marketing like this it is little wonder Olympus is in financial difficulties.

The images show an amazing amount of detail for such a small sensor camera. No doubt in large part due to the excellent Nikkor lens in the P7800 and excellent noise handling that retains detail as well. This is about as good as it gets for a camera with a tiny sensor!
