Received the microscope head, was branded as Eakins.
Build is what you expect for the price (
currently $230), plastic wherever it can be used. However, image quality is mostly very good, plenty usable for electronics. Zoom is nice and smooth. Good working distance.
Included eyepiece: 10x/22mm
Included barlow: 0.5x
Barlow thread: M48
Working distance:
~260mm with 0.3x barlow (too much).
210mm with the included 0.5x barlow (good for me)
FOV: 78.5mm at 3.25x zoom, 7.3mm at 32.5x zoom
Complaints:
- Included eyeguards are useless, just flat, I prefer raised ones.
- Image quality blurs once you go past 4x zoom (on the knob 0.65x to 6.5x), this is the point where you can see the optics change direction, so they must be "cheating" the zoom range in some way. This would be a dealbreaker for some. Small chance this is due to shipping damage, but, seems unlikely.
- This specific seller did not pack the item very well
I have another microscope that does 9:1 ratio and does not do this direction change thing that I can see and does not blur, so, I'm not sure why they decided on that technique.
