Thanks for the review and stellar samples. 28mm is my jam and I'm always looking for a smaller, more travel, more street friendly option than my Zeiss Distagon. Adapted to R5, it gets a bit long.
I bought this lens to use with my Canon R100 crop sensor camera. The crop factor gives me a prime lens very close to a 50mm (35mm equivalent). I've had it for a few months and am pleased with the results.
