Alpha 7R

Sony Alpha 7R

My Digital Era …….. SONY Alpha 7R




Sony Alpha 7R, with vertical grip, and the not so compatible ZM 15/2.8 Distagon T*

Never really in this stage of my life (LOL, at age 49) I will believe myself converting to digital photography. Had been a hard core film photographer for a long long time, since around 1985/1986. A few reasons I stayed with film, specifically Kodak negatives:  those equipment I used were all very dead ( Praktica, Rolleiflex, Contax ) and none of them were able to come up with a digital body. Yes Contax did have a Contax N1 full frame digital, but used a different lens mount. And also somehow I wanted a full frame digital. I do not really have a very valid reason why a full frame is a must, and I have seen enough fantastic photos from non-full frame cameras. Anyway, in December 2013, SONY launched the Alpha 7R, a full frame 36 MP digital mirrorless body, and by instinct I told myself this is the digital camera I wanted, and I placed a deposit and pre-ordered the Alpha 7R and there it goes, I am into digital photography!


I am probably using Alpha 7R in not really the way it was designed for, in a way  : ). Before I collected the body, I ordered a few adaptors:  Praktica to SONY E mount, Rollei QBM to E mount, Contax CY to E mount, Leica M to E mount, and Nikon F to E mount (no Nikon mount lenses I have at the moment, but wating for the ZF.2 Zeiss Otus). All of a sudden, I have a full frame digital body that is usable with all my Zeiss lenses, and in full frame mode!



Alpha 7R is using EVF electronic view finder. So every composition I see clearly the final effect in the correct exposure. There is no need to fully open and stop down the lens aperture like the conventional way of using manual lenses with lens adaptors. Interestingly my photos have been sharper than before, thanks to the SONY mirrorless focus magnifier, where a selected small portion of the composition can be enlarged for critical focusing.

There are actually two manual focusing aids provided by Alpha 7R: one is peak focusing indication, and one is focus magnifier. For peak focusing, areas in sharp focus will be indicated by some kind of shaded colour. However after using for a while I find this method not very full proof especially for wide angle lenses, and thus I stick to focus magnifier all the time now. The only other accessory I used with the Alpha 7R is the grip which I feel makes the camera much comfortable to hold, especially with heavier lenses.

The biggest disappointment I have with the Alpha 7R is that for Leica M mount lenses with focal length less than 35mm they are not totally usable with the 7R full frame sensor. For some photographic situations the corners suffer from obvious vignetting, colour shift and loss of image resolution. But some time it is a hit and miss thing where in certain situation the lens produces images that are very usable, like this one shooting using the ZM 25/2.8 Biogon below:

This is another shot using the ZM 28/2.8 Biogon at a toy stall in a rest point along Malaysia KL north-south highway. The photograph is usable with very good centre details.

The ZM 15/2.8 Distagon, despite a Distagon design, the rear of the lens is still too close to the full frame digital sensor and thus the corner light rays attack angle is still too steep. However, in certain situation the photographs taken were totally usable, like the shop display below. In fact a close up examination of the lights at the corners there are little colour fringing and image issues.

The ZM 50/2 Planar and the 85/2 Sonnar work perfectly well with the Alpha 7R. High resolution apparent, nice bokeh. The 85 Sonnar is kind of special. The photos taken on film already different from the rests of the Zeiss, and with a very high resolution it is well suited for the 36 MP Alpha 7R.

Zeiss always shines under low light condition  : )

Using medium and long tele lenses on Alpha 7R is really an enjoyment. I am getting much sharper pictures than before, partly thanks to the wonderful focus magnifier with mirrorless camera, and partly my deteriorating eye sight that cannot focus that well with optical finder anymore. I used a very old Schneider Tele-Xenar 135/3.5 taking a statue at Malaysia Batu Cave below.

Old lens with a new life ........


A few shots with Zeiss Contax 300 f4 Tele-Tessar. I have never taken such well focused shots with this lens before, partly also thanks to the easily adjustable ISO setting with digital camera that I can now use higher shutter speed as far as possible.

I jumped into Contax system with the reason wanting to try out Zeiss zooms. But after a while I go back to primes and not really working a lot with the zoom lenses. But I was quite please with the recent results with the Zeiss 80-200 f4 Vario-Sonnar tele zoom at the zoo of Singapore. Below is a shot of an iguana and I am impress with the high resolution apparent of the lens.

For the first time I am able to take some photos with the 180 f2.8 Sonnar at the night safari of Singapore with very high ISO setting at 6400. Direct JPG, noise is visible but no choice for such shooting condition.

I am a lazy photographer where post-processing is never my cup of tea. I am very please with the Alpha 7R in-camera JPG outputs. Like the one below shooting with ZM 21/2.8 Biogon T*, not only the photo is usable despite it is a M mount super wide angle, the photo attached here is pushed by one stop due to the original one being under-exposed. And I did the exposure adjustment on the original JPG file, not the RAW file.

Now I am waiting for an expensive and heavy Zeiss 55/1.4 Otus. But at present this lens is out of stock, despite its high price. Hope the lens can create some magic and sparks with the Alpha 7R.
