I am using a Nikon Fieldscope 82 ED for birding. It seems to compare well with other scopes in its price range and even more expensive scopes from what I have seen under favorable conditions and lighting.
The eyepiece I am currently using is the 25-75x zoom with the 82. The zoom works well. There is significant brightness drop off above 40 power. I think this is normal performance for this magnification at this price point. I am sure for double the price I could get 10% better performance…
My question is – would switching to a fixed magnification eyepiece provide any improvement in image quality, brightness or other advantages? With a fixed magnification eyepiece I would be giving up the ability to of finding the subject at 25 power then zooming in for a closer look.
If you have compared these 2 eyepieces I would be very grateful for your experiences and opinions and preferences. Other experience and insights are welcome too.
When compared to other scopes the diameter of the Nikon pupil lens seems to be much smaller than the Swarovski and Leica. Not sure how effects the final image or enjoyment factor.
