Sony A7 and A7r Hands On at PhotoPlus Expo

It was a very crowded Sony booth at PhotoPlus. The great thing was the Sony representatives were very accommodating to anyone who wanted to play with the new Sony A7 and A7r. We had our bag of lenses and was able to mount them all on the A7 and A7r - check out the 12mm viewfinder on the A7r above. The lenses include the following:

  • Voigtlander 12mm f/5.6 Leica Thread Mount on a helicoid adapter.
  • Voigtlander 35mm f/1.7 Ultron LTM.
  • Minolta 24mm f/2.8 Rokkor MD.
  • Contax G 28mm f/2.8 Biogon.
  • Contax Zeiss 85mm f/1.4 Planar with the Metabones Speedbooster and the standard C/Y adapter.
  • Zeiss 12mm f/2.8 Touit Distagon.
The cameras were pre-production and the use of memory cards to record the images was prohibited. We wanted to see if I could see immediate problems on the rear tilting lcd but none were glaring.  The only noticeable issue was color shift with the Contax G 28mm Biogon.  We're hoping that this can be remedied with the production models.

Below is the Contax 85mm Planar on a Metabones Speedbooster. As you can see it cannot cover the whole sensor but with APS-C mode on the A7 cameras the Speedbooster is still useable.

The Voigtlander 35mm Ultron LTM was a nice surprise.  This lens gives the NEX-7 some problems with color shift but on the A7 this was not the case.  The few snaps that we took looked great on the rear lcd.

The Minolta 24mm f/2.8 MD provide a nice wide angle image on the Sony A7.  It felt nice and balance on the slightly larger frame of the Sony A7.

We were very excited to mount the Zeiss 12mm f/2.8 Touit on the new Sony A7.  We had the A7's APS-C lens detection off to see how much the Touit can cover the full frame sensor.  The lens has a plastic shroud to protect the rear element and this showed up in the shot below.  The Touit works perfectly fine in APS-C mode.

Keukenhof Tulips by H. Stanbury and NEX-7

Here are H. Stanbury photos from Keukenhof also known as the Garden of Europe during the spring tulip bulb display. He used his Sony NEX-7 with the 18-55mm OSS lens and a Vivitar 24mm f/2.8 in Minolta mount for the photos.

Sony NEX-7 135mm Lens Battle Part 2

The 135mm Lens Battle Combatants Part 1 for Larger Pictures


Here is the second part of our NEX-7 135mm Lens Battle. Part 1 discussed 135mm lens handling on the NEX-7. We tested three prime lenses (Canon 135/3.5 LTM, Konica 135/3.5, Minolta 135/3.5 MD) and two zoom lenses (Canon 70-200/2.8L, Olympus 75-150/4). The zoom lenses were set at 135mm approximately. The lenses tested are around $100 or less with the exception of the Canon zoom.

The shots were taken at wide open aperture (f/2.8, f/3.5, or f/4) and the at f/8. We have labeled each sample a color and a number. The NEX-7 or lens was on a tripod, ISO100, and JPG Fine output. The samples below are arranged as follows:
  • One is shot wide open. It shows the full scene with standard editing.
  • One Crop is shot wide open with no editing. It is a 100% crop.
  • Two is shot at f/8. It shows the full scene with standard editing.
  • Two Crop is shot at f/8 with no editing. It is a 100% crop.
  • Three is shot at f/8. It shows the full scene with standard editing.
Here are the samples. Please comment on which samples you like best.

Sony NEX-7 135mm Lens Battle Part 1

sony nex-7 135mm lens f8

Composite of Four 135mm Lenses at f/8 with the NEX-7


Here is a first part of our 135mm focal length test used on the Sony NEX-7. This gives us an equivalent FOV of 202mm. We don't really shoot much at this focal length but we wanted to see how the NEX-7 and the various 135mm lenses worked with each other. These lenses are around the $100 mark with the exception of the Canon zoom. The lenses tested are:
  • Canon 135mm f/3.5 LTM
  • Canon 70-200mm f/2.8 L EF
  • Konica Hexanon 135mm f/3.5 AR
  • Minolta 135mm f/3.5 MD
  • Olympus 75-150mm f/4 Auto Zoom
First let's rate the handling. The Minolta and the Konica are the lightest of the group. This makes them the easiest to handle. The Olympus zoom is next and is most versatile being a zoom lens but it is longer than the Konica and Minolta. The Canon LTM is heavier than the first three but is the most compact in size. The aperture ring is at the end of the barrel and when adjusted, it also adjusts the focus. The Canon EOS zoom is the biggest and heaviest of the group. We do not have the Conurus EF NEX Smart adapter so we cannot change the aperture.

The NEX-7 was set on Aperture Priority, ISO100, and 2 sec self-timer. The camera or lens was set on the tripod. Here are the pictures of the 135mm lenses with the NEX-7.

NEX with Minolta 45mm at Devils Hockey Game

sony nex minolta 45mm md devils hockey
Game Winning Shootout Goal - ISO200 1/320 f/4.0


We were lucky enough to get nice seats to the New Jersey Devils vs Anaheim Ducks. We brought the NEX-5 with a Minolta MD/SR to NEX/E-mount lens adapter the Minolta 45mm f/2 MD Rokkor-X. The combination easily fits into a jacket pocket.

The 45mm f/2 on the NEX gives an equivalent FOV of 67.5mm, which allowed us to shoot the width of the ice from our seats. Here are a few shots from the night. Most of these are cropped which shows the lens' and NEX sensor capability.
