Once you've used an Electronic Viewfinder you can't go back. The ones on the Fuji X100 and Nikon V1 are excellent.

Thanks Neil - I was thinking specific to the NEX5 (or NEX5N). The viewfinder would be a good addition to digiscoping then?

The macro scene option speeds up the focus of the 30SEL lens?

After seeing this post http://www.birdforum.net/showthread.php?t=225964 I found this lens was designed for NEX system. Anyone is using it in digiscopy?
Besides being cheaper, is smaller then the Sony 30SEL and the black colour would look better also...
Still didn't decided what to use in digiscopy with the NEX5 but I'm enjoying it with the TMB92.
Enclose 2 of my favourite photos from February / March, my photo season...

Nice pictures DRodrigues, I have the Sony 30mm. The sharpness is very good. I always manually focusing. The distance from the pictures of Milvus milvus is approximately 25m. The picture of the Grey Heron is the Minolta MC Rokkor made ​​1:2.8 35mm W, distance 50-60m. The lens seems well suited. The light was not good. I'll take more pictures.

Love the Grey Heron image.

Hello
I've bought a Voigtlander Ultron 40mm lens. The lens works very well with all my Swarovski eyepieces 30x / 45x / 20-60mm. I use the UCA adapter. Compared with the Sony 30mm Macro, the Ultron is better from center to the edge. The lens is very compact. Here are two pictures of the Ultron with the 30x eyepiece, about 25m

The colour looks great. Nice one.

On my search for best eyepiece/telescope combos for cr-birding I received a TV Delos 17.3mm. I remembered to test it for digiscopy with the standard zoom lens of my NEX5 and it resulted on very low vignetting at lower 18mm.
Pentax XW20 might also work well but on my 5mm it vignettes a bit more than Delos - beware that I was using my Optolyth 100 so resulting scope magnification is 126x...
So when I will need to digiscopy wile doing cr-biriding the Delos 17.3mm is my new preferred choice but using the TMB92 + Nikon FSA-L2... http://www.pt-ducks.com/cr-telescopes.htm#Nikon_FSA-L2
All photos hand held and just reduced to 1400 and 75% quality - no crop or digital treatment.

Does someone already tested the 16-50mm compact zoom for digiscopy?
Does someone already tested the NEX5R for digiscopy? How was autofocus?

No one asked but I answer anyway... Why I prefer, because with this combo there is no vignetting at all (the FSA-L2 increases the eye-relief), minimum magnification is 29x vs. 36x on the Optolyth 100, and I have a 3.5x zoom without vignetting!

The first photo is no crop and is to show that there is no vignetting and the second is a crop. Birds at about 190m!

David,
Impressive setup and well explained in your blog.
Looking at the length of the extensions you may be getting a little bit of flex. I would more comfortable with some support under to camera end to keep the whole setup straight and minimise vibrations.

Although still not disgiscopied with the Delos at optimum distances, it seemed that the image quality wasn't much good, even with the reduced vignetting.
Today I managed to compare the image distortion resulting from the Delos and other eps, and confirmed my suspicions. Enclose the Delos, the Telescope Service SuperView 30mm 2", and the Vixen NLV40mm results, with the Optolyth 100 and the NEX5 with the standard 18-55 zoom (the 2" needed a special adapter SC to T thread - used without the 2" barrel). Although will compare again the 2" ep with the Vixen, on filed conditions, for now the Vixen is the best eyepiece for digiscopy with this combo...
Photos only scaled to 1400 and 90% quality. The Vixen photos were made latter so had to use auto program instead speed priority.

Today I saw the new 16-50mm compact zoom in a store and it might be better for digiscopy since the lens are smaller. Got even more curious how it performs on digiscopy.

New hybrid focus system can also be faster on digiscopy - dpreview released a review of the NEX6 http://www.dpreview.com/reviews/sony-alpha-nex-6
