    Sony Alpha Nex 6 for Digiscoping

    I've fixed that now Stu. Neil.

    Sony Alpha Nex 6 for Digiscoping

    Rob, Any 30 mm ( or more )fixed lens will eliminate vignetting and it's possible that a 28 mm lens will too. 20/24 mm is usually a bit wide. The 30/2.8 E Sigma is a very good lens with either fixed or zoom eyepiece but the 20/2.8 Sony will do a reasonable job although there may be corner...

    Sony Alpha Nex 6 for Digiscoping

    If you like Auto Focus then the Zeiss designed lens in the RX100 M2 is very fast and sharp. With the Nex cameras you need a lens like the Sigma 30/2.8 E to get the best out of it with AF (it is a bit slow though). Of course if you're happy with manual focus using the TLS APO adaptor straight...

    Sony Alpha Nex 6 for Digiscoping

    Rob You have lots of choice these days at all price points. The Nex 6 is more functional than the Nex 7 for digiscoping. You also have the Panasonic GX7 plus 20/1.7 lens or one of the Fujis. The best digicam is the Sony RX100 M2 but the Nikon P330 also does a good job. Compare features...

    That's good to know. Sounds like a big improvement on the X100. Neil

    That's good to know Wernier. My X100 takes about 1 second per frame to clear the buffer. Can you keep shooting while the camera is processing? Neil

    Yes, of course. I meant "Shutter Shock" Neil

    Sony Alpha Nex 6 for Digiscoping

    If you don't use RAW with the Nex 7 it's not too slow ( the Fujis were much slower) and you have more cropping room. Also, as you can hear the mirror on the Nexes I imagine there is is vibration at higher magnifiction and the shutter speeds are lower. Neil.

    Sony Alpha Nex 6 for Digiscoping

    I suspect that there is an inverse rule about increasing magnfication and dropping resolution. I find that you get sharper shots by manually focusing. Over 50x I mostly use it for video. Also you are magnifying any pollution/haze/humidity between you and the subject. Neil.

    Sony Alpha Nex 6 for Digiscoping

    That's the way I use it. I push it on then pull it back a bit so it extends out two mms. This also helps to block side light from hitting the lens. The Sigma is a very snug fit. Neil.

    Use both. I'm interesting in seeing how the 19 mm Sigma performs. Neil

    Sony Alpha Nex 6 for Digiscoping

    If you've got time can you shoot some comparison shots from the DCB 11 and TLS APO on the same subject. I'm going to try to do that tomorrow too as questions have been raised about which is best. Neil.

    Sony Alpha Nex 6 for Digiscoping

    Nice video clip at that distance. Wind is a problem at 70x, even a breeze. Some things to try - 1. retract the lenshood 2. drop the tripod height 3. fix spikes to the feet 4. hand a heavy weight to the center column eg camera bag 5. set up a wind barrier ( what I do in the hides is make sure...

    Sony Alpha Nex 6 for Digiscoping

    The Sony 35 mm should work well if it length is similar to the Sigma so that it still fits on the DCB 11. I should AF faster too. Neil.

    Sony Alpha Nex 6 for Digiscoping

    Jan, The Sigma 30/2.8 can be a bit slow , although it seems faster on the GH3 than on the Nexes. If I want to track medium speed feeding birds eg greenshanks , move to the 20/2.8 or the Sony RX100M2. For fast feeding birds eg plovers,sanderlings I go for the Nikon P330. The Sony RX100M2...

    Sony Alpha Nex 6 for Digiscoping

    You're right Niels. I'm often at iso 1600 with the GH3. I've been shooting thrushes in the park on dull days under hedgerows and would like more iso without noise. I did some tests recently inside and I had to use iso 1600 with the GH3. Checking with Colormancer on the jpeg they show a little...

    Sony Alpha Nex 6 for Digiscoping

    Robert, The Sigma 30/2.8 E is a good lens for digiscoping in Auto Focus Mode with the Sony Nexes. You set it up on the DCB 11 Adapter to center the lens to the eyepiece. If your happy with manually focusing using the TLS APO method then the 30/2.8 is a good walk around lens for...

    Sony Alpha Nex 6 for Digiscoping

    No. You need both pieces. For both viewing and digiscoping you need the eyepiece module. Neil.

    Sony Alpha Nex 6 for Digiscoping

    One of the things I like about the Sony Nexes is their low light capability (this time of the year I need it) . This photo of Grey Herons was taken at iso 1,000 in Autoiso at 1/60th second. I was using the Swarovski TLS APO so manual focus. There is no measurable noise in the photo , according...

    Yes, it should improve on what's gone before. I'll have to wait a bit though. Neil.

    Sony Alpha Nex 6 for Digiscoping

    I've never made it to Wyoming but it looks stunning. One day. The Nex 7 is about 1 year older than the Nex 6 and has a 24 meg sensor. Image quality is very good, especially when paired with a quality lens , like the Zeiss 24/1.8 E lens. It has an older processor so is very slow at handling...

    Sony Alpha Nex 6 for Digiscoping

    Frank, The Nex 6 quality is up to 40& better at the sensor level according to DxoMark and iso noise handling is much better . The Sony lenses are better too. It processes Raw much faster too. You have the Sweep Panorama Mode and the APPs you can load to the camera too for Timelapse and...

    Sony Alpha Nex 6 for Digiscoping

    The Sony 20/2.8 E lens should work well with the Sw 30x with little/no vignetting. I haven't used it on the DCA but on the UCA Adapter there is a little vignetting in the corners but it is easily cropped out. On the 25-50x there would be a bit more vignetting at 25x but should be less at 50x...
