Hello everyone!
I am a happy owner of a brand new M7 8x30. I love the form factor and the quality at the price point. Seems like a lovely piece of gear in many respects.
I do, however, have a concern that I'd like some insight in. Therefore I am humbly tapping into the collective intelligence of this forum. Hope you can help.
---> The issue I have is this: while focusing on a subject the center of the image is nice and crisp. The edges much less so. Seems like the bottom of the image circle exhibits blur closer to the center than other parts of the image circle.
---> By altering the focus I can make the edges truly sharp and in focus. But then I lose the central sharpness. Is this a case of pronounced field curvature or something similar?
---> Does your M7 8x30 exhibit this? Should I send my pair to be adjusted under warranty?
I own a cheaper Action EX 7x50 and it does not have this issue. Neither did I notice that in the pair of prostaff 8x30 that I tried (although briefly). Is this a characteristic of the wide FOV that the M7 8x30 has?
I'm pretty experienced in camera optics but much less so in binoculars so any help is truly appreciated. I'd rather not send the pair to be serviced unless it is certain there is something wrong with them.
(ps. I did use search but could not find definitive discussion on this, thanks again for all helpful comments :t
