On article Pentax K-1 Pixel Shift Resolution: Updated Field Test (211 comments in total)

New software will be coming out to compensate for these post processing problems. The dynamic range increase of 2 EV, allows chip designers to shrink the Pixel size, make a even bigger high resolution chip design. Conclusion = Big files, > dynamic range; a Win-Win.

On article Using third-party lenses on the Sony a7 / a7R (523 comments in total)

I NEVER use focus peaking as it NOT accurate in the A7R. Magnified focus at 7.2x is fine! Long lenses and telescopes is the real reason I bought the A7r. In that mode the Telescope hold the camera on a drive system or heavy tripod. Dampened fancy ball heads are a real No-No- they slip! Compact tripods are garbage, Don't ever buy them, ABS, etc, trash! Old legacy lenses are a real joy to me, fast 50mm primes, 85mm and 100mm fast lenses. Outstanding work also comes from the older Nikon 135mm F:2 lens. Astro work needs a drive, no drive blurry photos! Unless your doing the Moon which is very bright! Regards, Don

On article Sony may split off its imaging products business (71 comments in total)

If you look at the Past Photo companies in the 1920's till now. that had Giant holding companies as the top of the pyramid; we see in every case a detachment of "chain of command" and family caring. This has without question resulted in the eventual destruction of the product line. One only has to study, Exakta, Zeiss, Voigtlander of Germany to reach that conclusion. In the Asian mindset similar photo corporations have also come and gone with Aires, Leotax, Konica & Minolta, Mamiya, Pentax as examples. In the USA Kodak, Argus, Ansco, Polaroid , Candid Camera and Detrola are examples. Losing touch from the top down is a social disaster for many corporations as the bean counters of stupidity ( MBA's), sub divide talent & patents for tax purposes, BUT fail to realize that layers of bureaucracy and walls; stifles innovation within a corporation and sows the seeds of its own destruction! To my vision this is a sad day for Sony!

Sony may NOT be attempting to take over the Sports AF technology field. Personally I bought a Zeiss Loxia manual focus lens for this very reason, I want the focus control. Do i shoot sports, NO! Do most photog's shoot sports, NO! 98% of Photogs do NOT shoot sports, so why buy a A7r ll for sports. There's enough Canon & Nikon DSLR cameras to handle that small niche. I was after the large full frame chip, with highest resolution possible. Thats what a A7r is best at. The improved version A7r ll in shutter operations and passive AF is GOOD enough, too get GREAT sharp photographs. Regards, Don@eastwestphoto

On article A lot to Leica? Hands-on with the Leica SL (Typ 601) (1495 comments in total)

companies that change there lens mounts, have troubles in sales and thats a historical financial truth. adapters better be cheap on ebay for this NEW 'L" mount. I am wondering if there will be adapters at the Leica booth at Photo plus expo on thursday? I will bring my M5 with Summicron 40/2-CL lens and give it a try? For mirrorless Leica the Summicron 40/2 is the best lens ever made. Sharp, contrasty, small, light weight a win-win lens, that leica M purist shot down, rises again from the ashes! Regards, Don

I hope that lens is interchangeable and a telescope can be hooked up through a adapter?

A A7r ll firmware update can easily fix the raw compression error. Personally I only use Jpeg files in my A7r so i am not bothered by Sony RAW files, error's. With the A7r keeping the shutter above 1/160th is my main goal in legacy manual focus lenses at 7.2x. I gotten some incredible ultra sharp results from Sony Chips and its processing engine. I read Canon has broken the 250 meg file barrier, that chip interest me, as does Canon's 4M ISO scale chip for astronomy photos. If I attach my future camera of 250 Meg file to my largest telescope and crop the images, I should be able to see the lunar rover tracks on the moon from 1969. Watch out NASA there's a new technology coming.

On article Alpha dog: Hands-on with Sony a7R II (1125 comments in total)

I was disappointed with the AF ability in the A7r I currently own, so I been using 7.2x fine focus for over two years now. With the Zeiss Loxia 50mm F:2 I returned to the days of fine manual focus like in the 1960's. I also was NOT a big fan of the vibration in the shutter & its Noise! Still some of the Very best photos I ever taken , are with this camera. If Sony has truly improved these two factors I will seek the camera body out and test it. I am especially curious if the ISO 102,000 speed will be a God send for astro-photography or a curse? I didnt see any public videos with that feature? This could be a deep sky joy, if the body weight doesnt knock off the tracking drive of the telescope 5" & 6" I have? Its not shocking to understand Sony technological greatest, They own large amount of shares in at least 20 optical/ electronics firms and are number one in chip sales for 35mm full frame & cell phone applications, world-Wide....

On article Zeiss launches Loxia full frame lenses for Sony E-mount (269 comments in total)

Sorry lost a section because of the 999 character limit. Loxia 50mm focus helicoil jumps the image into DMF 7.2x focus as soon as you turn, which is wonderful. This is a manual lens diaphram so focus at f:2 and then close down, without changing the focus at all! All EXIF info is saved to the camera after exposure and viewing the image after exposure at max magnification revealed a very sharp image on my A7r. The image quality is the equal to the more expensive Zeiss AF lenses in Prime lenses for the Sony A7 FE series camera, just slower in use. If speed is NOT an issue for you or price, this is a very interesting lens.

On article Zeiss launches Loxia full frame lenses for Sony E-mount (269 comments in total)

My new Loxia 50mm F:2 arrived, so i got out my trusty Test Chart and ran a test on the Loxia 50 mm, Summircron 40mm/2 CL and Sony SEL2870 kit lens. All exposures shot at 1/400@F:4.5. Loxia has the best colors and image brightness, Summircron resolves slightly better than the Loxia; and the SEL2870 comes in third in resolution. The SEL2870 was shot at the 45mm setting on the Zoom. I used the Summircron with a Tinray Macro focusing mount L/M>Nex adapter. So that lens affords me 40mm view angle & macro focus and sharpness, but the colors are not as bright.
I used a Sony A7r for the test camera
Back to the Loxia 50mm, its smaller than normal for Zeiss, but its chunky heavy build quality is noticeable. Its a work of Art, for sure and its builder is Cosina. the Loxia is a great product , with beautiful color rendition and contrast & sharpness almost as good as my favorite lens the Summircron 40mmF:2 CL lens of Germany. Regards, Don@Eastwestphoto

In reply to:

ulfie: Why not just get a ZM 50/2 w/ E-mount adapter? Save money and get basically the same thing as the Loxia.

because a ZM lens would Not have the DMF 7x magnified feature a critical aid to precision manual focus.

I would have appreciated a back photo from DPreview, showing the contacts and lens mount. This series of lenses may be MF, but; I like seeing the data transmission contacts so i can compare with my other Sony FF AF lenses. I was never a English major in college, I went to college for Photographic technology and science and optics and mechanics and electronics are important to me.
I use MF all the time on Sony A7r & Sony Nex 7, I never trust anybody's AF system to be as good as magnified focus assist. Thus MF zeiss lenses using the time tested Rangefinder, SLR Planar design, with a modern aspherical elements, will hopefully be a very high resolution lens? I think the 50/2 is more to my liking, I have both of these lenses on a Contarex Bullseye SLR from yesteryear and a Contarex > Nex adapter also. The planar 50/2 was a amazingly great lens in the film days of Zeiss glory. Regards, Don

A color corrected lens would have been better choice like a Rapax off a Ciro-Flex, with a good Wollensak Anastigmat in 85mm F:3.5. They are dirt cheap on eBay, easy as pie to remove from the TLR body and one heck of a great lens for no money! 85mm would suit a A7r FF Sony rather nicely. Wollensak made great lenses, mostly forgotten these days. We can all think of better lenses for sure, But dollar/lb. value of an old Ciro-flex cannot be beat in Price! Sellers on Ebay practically give away those cameras. 120 film is dying in the USA. Already my long-long time photo house gave up processing E-6 120 rollfilm and now tells me 120 C-41 is on the way out also? Gee I hope NOT, but digital really has improved tremendously in the last 7 years, so the technological change is on.I will be waiting for the day, I can mount that 6x9cm digital back to my speed Graphic's and Linhof cameras!

Personally, I would have used a much better antique camera and shorter focal length lens! The idea proofs that the first company that makes a Graflok back in 6x9cm DIGITAL 100 MEG, is going to step into a huge unmet demand. Then folding press and view large format cameras will sky rocket in price! It's just a few years away!

On article Leica T (Typ 701) First Impressions Review (2257 comments in total)

This is a lousy review from Andy Westlake- Most old leica fans want to know if they can use an older leica M mount lens on this camera? If so how does a 50mm perform on it and what angle of view will cover the chip entirely without vignetting the chip? What size is this chip? m4/3, or APS-C? DPreview is a manufacturers review forum for New camera, new lens and they are so biased against photographers who adapt old lenses to new mirrorless cameras, its disgusting and obvious bias. I would match my leitz Leica summicron 40mm F:2 CL lens against any NEW lens made for this camera in zoom and a manual lens test would of allowed me to understand, distortion, chromatic abberation and image quality of JPEG and contrast. After all Mr. Westlake, we do buy bodies and use our old lenses! Wake Up! Don@Eastwestphoto

On article Benchmark Performance: Nikon D810 review (1988 comments in total)

If Nikon makes a serious Mirrorless DSLM, I would consider going Back too Nikon! I still have a draw full of high end Nikon AF lenses; waiting. Interesting that Nikon is buying Sony chips in full Frame, isn't it? You thought Nikon was king? Don't think I don't like Nikon idiot, I have five very expensive Nikon Rangefinders, and Five pro-SLR Nikon's. I made a living shooting Nikon Film cameras & even sold my D-70s a while ago. Still The konica Minolta Sony Nex 7 made a real believer out of me & so does the Sony A7r, so friends, Nikon cameras are just too huge in size and weight, Nikon DSLR are too large for the travel photographer, who needed Light, ultra compact, ultra precision digital cameras. Sony moved in with there electronics technology and bought a merged optical house who made great cameras going back to the 1920's. One day soon Nikon will make a serious DSLM in Full Frame of ultra compact size using the Nikon AF lens mount. I am waiting...... Don@Eastwestphoto
