Sony a7 torture test with Leica, Zeiss, Voigtlander rangefinder lenses

Seems like in summary, the camera is not very good at adapting rf lens.

Do better with dslr lens and seems good with the native Zeiss

Sony a7 torture test with Leica, Zeiss, Voigtlander rangefinder lenses

It looks bad with those wide angle rf lenses. But from my understanding the A7 does not have offset microlens. It is the A7R that has these offset microlens that will eliminate or reduce colour shifts on the edges and corners.

I have used the 21 Elmarit-Asph and 28 'Cron Asph with my M240 and the corners and edges are clean. But with the M240 Leica and CMOSIS resorted to using elliptical microlenses without any offset. Also, unlike conventional CMOS, the one in the M240 has shallower wells, allowing the light to strike the photodiode at a more vertical angle. This design is a departure from the M8/M9 CCD with offset microlens. Have a look at this link, http://brianhirschfeldphotography.c...st-evolution-is-revolution-leica-m240-review/

Leica also incorporated in-camera corrections for these wide angle lenses. This is the reason the M lenses now have 6-bit coding. Without lens coding and in-camera correction, I wonder how can the A7R identify the focal length of these rf lenses and apply the appropriate correction?

I think A7 & A7R are going to be big game changers.

Worthy enough that even canon sites mention them:

Technically this is not a Canon site. It is a site about canon.

Sony a7 torture test with Leica, Zeiss, Voigtlander rangefinder lenses

It seems like there's an awful lot of noise reduction and/or poor JPEG compression in the sample images considering that it's a full frame and pictures were at ISO 400. Hopefully those are only because of the preproduction firmware.

On a side note, Steve Huff says that he'll be testing both models with RF lenses in about 9 days.

The A7R needs the offset lenses more than the A7 because the pixels are much smaller.

already preordered via b&h photo. Now the wait is excruciating.

For those who want to see a preview...

Thanks! Great video.

BTW, he appears to say that the 7 is plastic and the 7R is magnesium. Is that right? I cannot corroborate that info anywhere on the internet.

I. Am not wrong the a7 has a polycarbonate front panel while the a7r is full magnesium alloy

Most new models he review are mostly postive.

Yep but he also said there is no difference in the feel.

The A7R needs the offset lenses more than the A7 because the pixels are much smaller.

The M8 with 10mpx and 1.33 crop and M9 with 18mpx have offset microlens. The pixels are larger than those in A7/A7R.

It appears Sony is saying, if you want to use rf wide angle lenses, you have to buy the more expensive A7R. As seen in the above link, the preliminary results with using the A7 with rf wide angle lenses are not good. Let's wait for further test results.

not really. if you listen closely, the announcer made a few gaffes.

and the presenters generally look bored.

Well, the A7 is marketed as a "great and affordable entry into the world of full frame" while the A7R is targeted at "Photographers who require the utmost in detail" - so they really are designed for different needs.

That being said, why is everyone expecting Sony to give a d@mn about making sure the A7/A7r is optimized to work with non-Sony RF lenses? They will make sure their lenses and their cameras works well together. The rest is your own risk.

Then Sony better make some awesome lenses tat can fully resolve those sensors. Nothing in d FE mount interests me other than d Zeiss 55/1.8. Sadly.

stick with your lux and your CVs. you won't go wrong

those lens + M240.

NS, where did you gather that A7 does not comes with offset micro-lenses? I have expected both new sensors to have offset micro-lenses since it is a feature that has been mentioned in the same breath.

The M240 sensor was specially designed for Leica M lenses, hence the shallow well and more elongated micro-lenses. Sony sensors are probably also designed to accept incident light from a particular angle when paired with native mount lenses. When you slap any adapter that changes the distance between the rear lens elements and the sensor, you would have also changed the angle of light coming through. IMO, the edges will still take a hit in performance.

While not RF, I am also curious to know how the A7r will perform when using alternative UWA lenses with adapters.
