On article Sony a7 III Review (2164 comments in total)

DPreview,

I appreciate the new format of your reviews, with staff comments at the end, and combined with the excellent review video segment. Just like the Sony a7iii set a new standard for others to shoot for, so did you.

Thank you,
d2f

SIGMA 105mm F1.4 DG HSM in E mount, I think I will be buying that one.

I think Samyang is on a roll. I own the 14mm SP and it is a pretty good (but not perfect) lens for astrophotography. When combined with my a7s the corrected images are excellent. I am on the fence regarding the 85mm since it is a manual focus lens and know from past experiences with the Canon's 85mm 1.2 that perfect eye focus is difficult when shooting wide open while at min focus distances. Kind of hit and miss. So I will wait to see the reports on the 50mm before deciding on with to buy next. In parallel, recently I have been building up my Sigma APS-C (1.4) lens collection and looking forward to the release of the Sigma 56mm 1.4 for my 6500. If I get that lens I will pass on the Samyang 85mm 1.2. It is a great time to be into photography.

Speaking only for myself: The problem with any optical mechanical means to an end is, it is not completely reversible. Yesteryear, photographers used to pre-visualize the image, compensate the exposure for the film attributes, then take the shot and work out the image in the darkroom. Today, I believe a majority of photographers take the shot and use software applications in post to create the image they had in mind. These software apps make that the process all so easy and repeatable, while retaining the original image be it film or digital media sourced. So in this particular case, there is nothing gained by purchasing the lens.

Does anyone believe for one moment that Apple executives care what you think about Apple? If you were sitting on hundreds of billions of dollars of profits would you? My guess is, from their perspective you are nothing more than a self center minority that complain about everything to hide the fact that cannot afford the quality products they offer. Prove them wrong by stop complaining and just move on. Buy what you perceive is best for you and stop trying to change what you cannot change and focus on improving yourself.

Is it time for DP to add a 3D stabilizer sub section tab to their menu? Maybe between lenses and phone. If there is no space then consider dropping printers, lets face it that market has slowed to down a bit, for example what is the latest printer from Canon? If that doesn't work consider ganging printers and stabilizers under a new sub menu "accessories". Just a thought.

In the future can dpreview evaluate the cameras with Pixel shift mode with respect to Astro photography application? For example, a7rIII camera and lens 50mm 1.8 on star tracking head like a iOptron SkyTracker Camera Mount. I would like to see what if any difference the Pixel shifting provides. Thank you.

d2f: Since there is nothing unique about mass produced batteries, I wonder if other cell phone manufacturers have the same issue, battery charge capacity degrading and have done the same thing as Apple, throttle down the CMOS processor clock to extend battery life. If that is the case then we can expect those other manufacturers to follow Apple battery replacement program in 2018. If not then the other cell phone manufacturers just let the owners experience degraded operating time which is more likely the case. In that case they still may opt to offer a lower cost replacement battery offer not to be out done by Apple.

In my opinion, there are two rules crowdfunding companies follow: They never use their own money and second if they can separate you from your money you do not deserve to have it.

Stolen Hasselblad Gear Reunited with The Camera Store
by Evelyn Drake
Within 48 hours of thieves leaving The Camera Store in shambles of shattered glass and robbing us of nearly $35,000 of specialty camera equipment, Constable Tony Hogendorp and Constable Paul Teworte from Calgary Police Service have recovered our stolen Hasselblad equipment. Two suspects were taken into custody outside a Calgary mall Monday afternoon, after meeting an officer who answered a Kijiji listing.

Amazing.

I hope that Sony will some day allow end users the option to turn off the noise reduction features and allow post processing to correct the noise.

Amazing. At some point legacy lenses should reach their ceiling and limit the system performance. Long before that time sensor technology will evolve, maybe in the direction of high speed electronic pixel shifting or a new low noise organic semiconductor technology combined with direct 3D memory write. Memory storage as we know it now will likewise evolve beyond semiconductor based memory cards. Maybe reaching molecular level densities allowing terabytes of storage in the size of a grain of salt. Optics may evolve to flexible adaptive elements correcting allowing for dynamic optical phase alignment and corrections for even atmospheric distortion. At this point anything is possible.

On article RIP Lightroom 6: Death by subscription model (1633 comments in total)

if you put yourself in Adobe's shoes it makes sense. They need a steady income and selling stand alone software followed by incremental upgrades does not achieve that goal. While the general public will always have the low end software, high end consumers and professional markets will have to adjust the concept of leasing the software. By offering LR and PS together Adobe is trying to project an image of value. When you consider the purchase price of each and the follow up upgrades costs you are breaking even if not coming out ahead over time. This also expands the exposure of PS to more LR users who would not normally consider purchasing it. Having both should be beneficial to the end user. The governing rule being you buy what appreciates and lease what depreciates. One could make the case that software falls into the later and in turn consider the lease option as not a bad choice.

Dante Birchen: So it's popular is it?

The Lens rental review states the Sigma is a bit soft and the reviewer would opt for the Canon version instead.

Speaking only for myself, as an amateur, I would opt for the Sigma since the OSS out weight the slight softness that was reported. Personally, I did not see any softness in the sample images in the review, that is to say it is sharp enough for me. Again only speaking for myself, I know from my past images that a sharp lens that is hand held can result in less "keepers" compared to another lens with OSS under certain conditions. If I missed capturing that golden opportunity, the once in a lifetime image, because of camera movement on my part I would kick myself for not getting the lens with OSS when I had the chance.

Thank you for the interesting analysis. Were you able to reproduce the results in a controlled lab environment? If so then the test should become part of your future benchmark tests that are used to evaluate digital cameras performance.

In reply to:

mosc: I would love to see how the sigma stacks up against the manual focus Venus Optics Laowa. I don't think f1.8 vs f2.8 is that big a deal to most (lets call that even considering the Sigma is 14mm and the Laowa is 12mm), even autofocus stops being that valuable at this kind of width, but if the Sigma can match the Laowa's party piece (not making me nauseous at well past 90 degree FOV), I'd be interested.

I agree it should be interesting to see how the two stack up against each other and others from Canon and Nikon. Googled the Laowa lens and found one star image corner view which shows some coma. When compared to the Sigma corner star image example it "appears" that Sigma "maybe" slightly better. If this is true then Sigma may have edged out their completion in this one unique application. http://www.the-digital-picture.com/Reviews/Venus-Optics-Laowa-12mm-f-2.8-Zero-D-Lens.aspx

Nikita66: love the idea of this 14 1.8.

Now, pleeeease do an APS C version:: compact 10mm 2.8 - but with removable hood and filter thread.

Do you mean something like the Rokinon 10mm f/2.8 ED AS NCS CS Lens?
