I have used a Meogon S 80mm lens for the last 16 years trouble free for all my 6x6 work. I have the f2.8 version which is hard to get nowadays as I believes its no longer made. At anyrate, I remember reading an enlarger lens test from a photo rag in the UK when I lived there in the early 90's that compared the Meogon S 80mm f2.8 with all the other similar glass from it's peers. It actually had better performance than the componon S and Rodagons across all apertures. In fact the meogon had the best control of distortion than any of them over more apertures as well. I would not hesitate to recommend this lens. I am not sure on the newer version of the 80mm as it is only f4.5 I believe. I would assume it would be comperable buy YMMV. If you can find a used f2.8 version, then jump on it.
