Voigtlander 12mm Ultra Wide Heliar Sony A7r Samples

Here are some shots of Brooklyn produced by the Sony A7r and the Voigtlander 12mm f/5.6 Ultra Wide Heliar. This is the 1st version of the 12mm lens in Leica M mount.  You can see the color shift but it's not intrusive for these snaps.  The Voigtlander 12mm is compact and looks great on the A7r.

Sony A7r with Contax G 28mm Biogon Test Shots

Image
Manhattan from Brooklyn
We are still learning which lenses play well with the Sony A7r and we found one that's not so friendly. The Contax G 28mm f/2.8 Biogon, shown in our previous post, is a non-retrofocus rangefinder lens which means that the rear of the lens is closer to the film plane or sensor. This causes the light at the edges to hit the Sony's A7r full frame sensor at oblique angles which results in color casts. This happens with the Leica M9 and M240 but is corrected with in-camera with software. The color cast can also be corrected with CornerFix or Light Room's Flat Field Plug-in, discussed by Tobinators here. We did not correct the images here for color cast.

Apart from the color cast, the Contax G 28mm Biogon performed well. We love the sharpness, contrast, and color the lens and the Sony A7r sensor delivers. Most of the shots are at f/5.6 or f/8 as we tried for the sweet spot of the lens. The A7r was set to Aperture Priority as there was plenty of li…

Trainspotting with the 40mm M-Rokkor and Sony A7r

Image
Here are some test shots with the Minolta 40mm f/2 M-Rokkor for the Minolta CLE. This is the multicoated version of the Leica 40mm Summicron-C. We used the very compact 40mm M-Rokkor walking around a local train museum with the Sony A7r via a Leica M lens adapter. The shots up to the handcart are all done at maximum aperture of f/2. Manual focus was very easy with using the viewfinder magnification of the A7r even in the mid-day sun. The mid-day sun also guaranteed high shutter speeds at ISO 100 and f/2. All the shots are handheld.

















The shots below are at f/5.6 up to f/11. We need to test this lens more but the sweet spot is definitely at f/5.6.




The CSX 152 (GE AC4400CW diesel-electric locomotive) and the CSX 7305 (GE C40-8 [Dash 8]) was shot during the afternoon sun.

The lens has been great on the Minolta CLE and NEX-7 and it performs well on the full-frame A7r. The lightweight and compact 40mm M-Rokkor with a fairl…

Konica Hexanon 57mm 1.2 on NEX-7

Image
We've seen what the Sony A7r can do with the Konica 57mm f/1.2, now it's the NEX-7's turn. We actually took these shots almost two years ago. The 57mm on the NEX-7's APS-C sensor produces an equivalent field of view of 86mm. The lens having such a large aperture at f/1.2 is perfect for isolating your subjects.


The shots are most likely at f/2.0 instead of wide open. We had to stop down since it was producing better results that day. We love greens that are produced by the Sony sensor and the shots below show it well.

Can you tell a big difference between the 2 year old NEX-7 shots vs the recent A7r shots? Our biggest lesson is to process your files as soon as you can.

Sony A7r with Konica Hexanon 57mm f/1.2 shot by NEX-7 with a Leica 60mm Macro-Elmarit-R
Here are some of our test shots from the Sony A7r and the Konica Hexanon 57mm f/1.2 lens. The lens was mounted on the A7r using a Konica AR lens adapter. We wanted to test out the lens at f/1.2 the whole time and it was fitted with a 4X ND filter to battle the sun. The 1/8000 shutter speed and 50 ISO of the Sony A7r helped at times as well.

The Konica 57mm played very well with the A7r per our standards. All the shots were handheld as we rarely use a tripod. The focusing, at such a shallow depth of field from the large f/1.2 aperture of the lens, was manageable on the A7r. The weight of the lens would make us think twice of walking around with it but the results are hard to argue with. The details shown at f/1.2 is remarkable even at the outer edges of the shots.

First Snaps with the Sony A7r

Image
Here are our first snaps from the Sony A7r. The 90mm f/2.8 lens from the Contax G was perfect for our trip to the nursery. The camera was set to shoot raw. These images were sent to the smartphone via the Sony A7r's WiFi and NFC feature. SnapSpeed from Google was then used to tweak the files and here are the results.










The wireless transfer of files are so easy that we are thinking of getting the EyeFi memory card for the NEX-7.

More on the A7r in the days to come.
