Return from a long hiatus: Sony a7 and a7R
« on: December 21, 2013, 07:57:31 PM »
Hi Everyone,

Its been a long time since I last visited this forum. I just received a Sony a7 and a7R and have been spending some time working with the cameras. In a word, I love them. Here is a very severely cropped picture of two birds that I photographed from backyard with a Minolta 100-300 mm f4.0 APO lens (long discontinued). This has been used with a Sony a7 with the LAEA-4 adapter and the camera set to an ISO of 2000. This high ISO was needed to counteract my hand tremors when hand holding the lens at 300 mm. Autofocus was set to the center spot and the camera was focused on the bird's head. Considering the severe cropping and the high ISO, I thought you might find these photographs of interest.

The autofocus is certainly spot on Brian.  The eyes are sharp as a tack on both of them.
I am curious though.   Why the A7 AND the A7R?  ....john

Hi John,

My publisher, Rocky Nook, has given me a contract to write a volume on both cameras. My wife, Carol, and I have previously written books on the Sony A77, the Sony NEX-7, and the Sony NEX-6. For the next two months,  we will be taking pictures with both cameras to learn of their strengths and weaknesses. Because of the paucity of full frame NEX lenses, we are checking the usability of camera adapters and legacy lenses.

Both cameras, as would be expected, work well with the LAEA-4 adapter. Also we are using some of our NEX-6, and NEX-7 lenses on these full frame cameras to check how well they handle the APS-C lenses. As a side note, we found that the LAEA-4 adapter focuses the Minolta AF 500 mm f8.0 Mirror lens and the 90 mm Tamron f2.8 Macro. I just spent the day shooting a 20 mm f2.8 Nikon and the results look pretty good. It takes a little practice, but one can manually focus this lens quickly with the aid of the Sony's focusing aids.

Thanks Brian Matsumoto for the information's, even if i don't own any of the FF-E mount body's i am interesting  to know how they work with legacy lens. I use Minolta MD/MC lens on Nex 6 of my wife and i must say i am very impressed. Before one week i got the 18-105G an impressive lens and a lens that i intent to use in a future FF-E mound body with the reduction of half pixel ;)
