Hi all
I would like to ask question related to image quality possible to get by using FSA-L1 adapter and Nikon DSLR together with ED82.
First, apologies if the question has been already answered, I searched through the forum but could not find.
Background: I have been digiscoping for some months now and I must admit I have been hooked and am quite pleased with the results achieved so far. Setup used: ED82A, DS 30X eyepiece, Canon Powershot S95 mounted with a third party bracket with “swing arm”. My experience so far:
+ The setup is capable of delivering sharp pictures, provided i) one pays attention when focusing (since DOF is narrow) ii) vibrations are eliminated or at least mitigated iii) bracket is correctly centered (somewhat tricky) iv) some luck and some random factor (I try use timer to reduce vibrations and burst to increase likelihood, sharpness varies between pictures in a burst)
- Pictures tend to be on the soft side (even though sharp, if you see what I mean) and losing some contrast – contrast that can be partially remedied in the digital lab. The higher the camera zoom, the softer the pictures.
- Most pictures are taken with camera zoom between half zoom to almost full zoom attempting fill the frame as much as possible (still, cropping is often needed). Say 50-90 mm on 28-105 mm scale (35 mm equivalent). According to Nikon this would correspond to a composite focal length 1500 mm – 2700 mm (again, 35 mm equivalent)
- Some chromatic aberration is shown, not always though (depending on subject and contrasts), but I don’t regard it as a real issue. It can be partially fixed with Canon SW.
- Bokeh is not really pleasant. Nothing to do about it I suppose.
My questions in short:
Will I get significant image quality improvement (sharpness) with FSA-L1 and a DSLR compared to the setup I use (and understanding the equivalent focal length will be limited to 1500mm, according to Nikon)
Will the camera and adaptor weight (say 700/800g) be an issue from a balance point of view? I have a heavy duty Manfrotto tripod but still…
Will an angled scope be an issue to handle? I suppose not but would like to have it confirmed by users.
Sorry for long post.
