Review: No issues using Pentax lens - I have a handful of old Pentax lens and wanted to try some out on my Panasonic G7. Had no issues with mounting and everything works great. Tried photos and video and the quality was still there.
Review: Excellent product - This is an excellent product, worth the slightly higher price compared to bargain adapters. It is solid and secure, rotating into place with a satisfying click. I can't comment on that auto focus aspect, because I use this adapter only with manual lenses. But in all respects that I'm familiar with, this adapter functions very well.

### ⭐⭐⭐⭐⭐ No issues using Pentax lens
*by T***A on October 2, 2025*

### ⭐⭐⭐⭐⭐ Excellent product
*by A***R on November 2, 2023*

This is an excellent product, worth the slightly higher price compared to bargain adapters. It is solid and secure, rotating into place with a satisfying click. I can't comment on that auto focus aspect, because I use this adapter only with manual lenses. But in all respects that I'm familiar with, this adapter functions very well.

### ⭐⭐⭐⭐⭐ Works as expected!
*by A***R on December 22, 2023*

Got some funky lenses recently through various camera acquisitions and I thought it'd be fun to try them on my Olympus EM1 Mk2, particularly the 400mm that steps up to 80mm on MFT cameras. The adapter works flawlessly! It;'s solidly built and I've had no issues or wobbling. I would not hesitate if you need to adapt some old glass to mft cameras!
