On CreativeLive to host one-day event with Art Wolfe article (33 comments in total)

I watched the whole event and I think that anyone who really wants to enhance there vision should for sure watch this.

Art is truly a master image maker and is also an excellent instructor.. I wish I could afford one of his workshops.

On Nikon D610 Review preview (340 comments in total)

I wonder why the Sony A7 does not have as good high ISO performance as compared to the D600/610 ???

Zoomer52: How come with all the sample images you posted, there is not even one with an ISO less than 400?

I just look at base ISO and raw. Looking at the Gretag Colorchecker chart, the blue patches, the Fuji files for sure do some weird stuff or at least how LR interprets it, basically the colors looked smeared giving an impression of no noise or more luminance reduction.
I am not sure if CPR turns off noise reduction on LR for these tests

On Sony Alpha 7 Review preview (1614 comments in total)

I own both the Sony A99 and now also the A7.
I am puzzled on how the A99 IQ and high ISO is better any ideas?

Akpinxit: AA filter or not - all I can see here is the same IQ as seen on the rest of mid\high end latest D\SLR

Hence the reason why I wish Pentax would have stuck with 16MP with the new features of the K-3. Oh well market pleasure wins again. Sweet spot for AP-C is 16MP

steven_k: I love m43 even though I don't own one anymore.
I just could never get over the noise even at base ISO.
Yeah, I guess I can shoot in JPEG and have the camera apply noise reduction yet that limits the detail. Just look at any of the new m43 cameras here on DPR, check ISO 200, RAW and look at the blue square on the color checker chart, noise. For me I would have preferred m43 stayed at 12MP, I think this is / was the sweet spot for the 4/3 sensor.

Ok maybe I went a little overboard. I was looking for a small landscape kit to compliment my FF setup.
Yes I do print my images on my own HP Z3200PS and yes I noticed noise in the sky. I don't se this on my FF DSLR.
Right now I am shooting a Fuji X--E1 and looking forward to the x-E2. Of course there is a workaround for noise with m43, it's called ETTR, many articles about it especially in regards to the Olympus EM5. Is the Fuji an excellent camera? Of course not, but for me, where AF sped is a non issue and all I am interested is optimal IQ in a small package, my Fuji delivers now with much better raw support.

On Olympus OM-D E-M1 Review preview (2065 comments in total)
In reply to:

PhotoKhan: ISO noise performance is far from impressive, right from direct observation.

I don't think I've seen such a poor ISO 200 performance from a $1250+ camera in a long time.

Also, why are so many photos in the samples gallery significantly underexposed?

Again looking at the DPR comparison look at the Color Checker chart the blue square at ISO 200 RAW there should be no noise but there is. Sure if you shoot JPEG, Oly takes care of it or if you shoot RAW you can turn on NR but at base ISO one should be able to shoot RAW and process without NR and get clean results. I just don't see it.

steven_k: I would have stuck with Olympus, but even with the new EM-1 at base ISO do a comparison RAW ISO 200 to the Fuji X-Pro then hover the blue square on the color checker chart. Olympus has very visible noise where as the Fuji has none.
Even at ISO 100 which basically giving the Oly one more stop of light there is still noise. What's up with that?

Don't get me wrong the Olyqmpus is an amazing over all camera, but for me a base ISO shooter, like to shot landscapes at F8, the Fuji produces a noise free image.

Charles, I print my own images on my HPZ3200 24" printer.
I printed numerous 16x20 from my now sold Oly EM-5 and for landscapes my Fuji produces a mush cleaner looking print.

Believe me I am no Fuji Fanboy, As Brett pointed out! the EVF sucks IMHO on the X-E1 but for static subjects it does the job.

I will repeat, the Oly is for sure a better al around camera yet to me does not excel at anything, it's just good at everything, which fork 99% of us is good enough.

For what I shoot I am still saving up for a used Leica M9

On Fujifilm X-E2 Preview preview (454 comments in total)

Ok what about 12bit Raw versus 14bit RAW shouldn't the X-E2 have better DR when shooting RAW?
I also like the fact that the EVF now has a wysiwyg mode, I find this very handy, more like Sony EVF. Yeah, this feature could probably be added to the X-E1 yet I am not sure. I pre ordered the body, I want to compare side to side with my X-E1 and see if there really is any difference in IQ because of 14bit RAW

On Sony Alpha A7 / A7R preview (2372 comments in total)

Hmm, I was under the impression the new A7 has a better EVF then the A99 yet how I read this preview is that it's the same EVF that's in the A99

In regards to lenses, I still think there is going to be a lot of disappointed people when they try there WA Leica M lenses, also 36mp and using an adaptor, yikes there goes the perfect alignment which even the mighty D800 has issues with.

I think the one WA lens that should perform well is the Leica TRI Elmar because of its retro design. Forget about all the WA voigtlander or Zeiss ZM WA no way is that going to work.

Lastly, in the USA available 12/1 For the hell of it i placed an order this morning 9:00 am EST on amazon for the A7r and the 35/2.8

I bet it will be 3-5 months before I ever see the camera. I am just remembering back to the NEX7 days, even though they had the big flood that caused a huge delay, the Zeiss 24/1.8 was impossible to get forever, I wonder if Sony has made an investment in Zeiss to be able to ramp production

J D Tranquil: As an owner of a Fuji X system camera, I would like a fast, constant-aperture, zoom lens in the lineup, 24-70mm f 2.8 to be exact. Or even f1.8 like the Sigma zoom (f18-35), that's even better.

I shoot an X-E1 with the Fuji 14, 18-55 and 60mm lenses for my small landscape kit. I mostly shoot at F5.6-F8. I have done numerous comparisons between the 35/1.4 Zeiss 32/1.8 and my zoom at F5.6 and F8, I can't really see a difference, I wanted to believe that the primes would be better yet I can not personally prove this on my own testing.
So here we go again, the new 23/1.4 will this lens yield a better result shot at F5.6 over the zoom??

I guess for me I have found the 18-55 zoom is really a great little lens and unless you shot low light and need the faster lens I just don't see it. What am I missing?

David, if you had just hanged on a little longer with you X-E1 and shot RAW, Iridient Developer transformed the X-Trans sensor into a real gem IM HO

To bad they went with he GH-2 sensor and not the newer GH-3 sensor.
I think Panasonic blew it.

On Olympus m.Zuiko 17mm F1.8 first impressions and samples article (255 comments in total)
In reply to:

steven_k: I purchased 2 of them hoping the first one I got was a dud, but it wasn't.
I shot the lens at F4 optimal setting for this lens at infinity focus for landscapes on my OMD and I can tell you hands down this is not a good lens for landscapes.
No where near as good as the 12, 25, 45 or 75mm lenses.
My opinion is that this lens is probably a good street shooter lens.
Not what I has hoping for.
I guess the problem is at the end of the day it is a 17mm lens, and to make a tack sharp 17mm lens for 500.00 is probably almost impossible.
Though the Oly 12 which is by far not perfect, I feel does perform better over all yet again a 700.00 lens.

Oh we'll.

on the other hand, I did try a NEX 7 with there Zeiss 24/1.8 and to be honest, very sharp in the center and yet soft corners, again not a good landscape lens. A great street shooter lens.

I think at 17mm focal length ,the designer has to choose on what it will be good for, more close subject images where corner performance is not an issue, or try to design something more flat field.

Yet at the end of the day as others have pointed out, it is a 17mm lens, not a 34mm lens. To produce a high quality 17mm lens would I assume would cost a lot more money, like the Oly 75mm, and be much large
