Sony A7 and A7r Hands On at PhotoPlus Expo

Sony A7r with a Voigtlander 12mm Lens and Viewfinder
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 m…

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 s…

Sony NEX-7 135mm Lens Battle Part 1

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 LTMCanon 70-200mm f/2.8 L EF Konica Hexanon 135mm f/3.5 ARMinolta 135mm f/3.5 MDOlympus 75-150mm f/4 Auto ZoomFirst 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 h…

NEX with Minolta 45mm at Devils Hockey Game

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.
