a7R and a legacy lens
« on: January 17, 2014, 07:43:41 PM »
Hi All,

I've been working with my a7R coupled to some of my older Nikon lenses and have been very happy and relieved. Happy because they work well. Relieved because the a7R has so few lenses and they are not in the focal lengths that I like to work with! To an extent, I have been working with adapters and using my lenses with manual focus and I thought you might like to see the how much quality is retained by using this combination. The picture of the tile roof was taken with a 300 mm MF f/2.8 Nikon lens. Shutter speed was 1/400 of a second, f8.0 aperture, AWB, on a heavy tripod. There is a shot showing the full frame of the sensor and then there is a close up of the center of the frame (666 x 1000 pixels). I thought you might enjoy seeing the results. Let me know what you think.

As a side note, the mechanical shutter vibration is not so bad with this camera. I've read reports stating the camera is virtually unusable when used with long telephotos. This has not been observed by me--knock on wood.

You could not knock the image quality of these images Brian.  Very sharp...john

Thank you.

I feel happy with the following MF lenses on the a7R: 20 mm f/2.8, 28mm f/2.8, 55 mm f/2.8, 105 mm f/2.8, 180 mm f/2.8, and the 300 mm. All of these are the older AIS lenses of Nikon. This provides sufficient span of focal lengths; however, I do miss autofocus and image stabilization. To compensate the loss of image stabilization, I use an ISO from 200-800 and so far this has allowed me to keep the shutter speed fast enough for handholding the longer lenses. The main thing I miss is the autofocus, but thanks to the depth of field scale, I set the 20 mm to its hyperfocal distance and at f/11, everything from infinity to 2.5 feet is pretty sharp. Once I start using the 180 mm or higher telephoto, I mount the camera on a tripod.

I miss the convenience of a zoom, but I feel I have gained in image sharpness. For what it is worth, I feel the 28-70 mm kit zooms for the a7 does not measure up to the single focal length Nikon lenses. I sure hope the Zeiss 24-70mm provides fantastic optical performance.
