The Canon is typically pretty soft with fairly high CA wide open at f1.8, though its sharp enough for my uses on a m43 body. The focusing however is far from optimal - this is not designed to be a MF lens and the feel of the focusing ring speaks to that. It is usable, but it is nowhere near the feel of even the worst of the MF lenses you typically find being used with adapters on mirrorless cameras. I only use it because the AF motor is broken on my copy and as such I couldn't really sell it when I divested my other Canon gear. If I was looking for a manual 85mm f1.8 I'd go with the FD mount version.I would be curious to see how it compares to Oly 75mm (both at f1.8). Could be a much cheaper MF alternative. Aperture control is not important cause these lenses are meant to be used wide open (sometimes with ND filter).

Yes - I don't have a Canon body anymore to stop the aperture down so I can only shoot it wide open. There is indeed quite a bit of chromatic aberration, exhibited as both purple and green fringing, but its usually fairly easy to correct in LR. From what I recall on my 5DII, CA is much better at f2.2, and its definitely sharper at that aperture, but you lose the perfectly round bokeh since it doesn't have rounded blades. Its sharp enough for me wide open.Pretty good result, is it at f1.8?
I found Canon 85mm to be very sharp at f1.8 used on T2i, it exhibit green fringing though.
Agreed. As I said above. MF is very difficult with this lens because of how bad the focus ring is. The only reason I use it is that I have the lens and the AF motor is broken so I couldn't sell it. I should probably just get the 75mm, but I'd really prefer a 200mm equivalent (with an f2 aperture) if Panasonic is listening...As much as I love the Canon 85/1.8, especially given it's low price, the O75/1.8 is the better lens with no doubt in my mind. As for using the 85/1.8 for m43, the biggest con is the MF ring and it's lack of smoothness and feel.
I believe they're referring to the feel rather than the difficulty, when Canon lenses of this generation have a bit of use I find the focusing ring gets... gritty? for lack of a better word... due to sand or other dust between the ring and the body, they still focus fine and are perfectly serviceable however they loose the well damped silky smoothness and feel... rougher?I disagree with being difficult. I just got my cheap little adapter today for my GX7. I find using my 85 1.8 easy with MF. I can get focus quick and accurate with it.
this was just playing around the yard at f2.0
Yes, that's pretty much it. MF is completely serviceable with this lens its just that it is gritty/notchy and the focus through is very small from min focus distance to infinity making it more difficult to acquire precise focus then a lens that was built specifically to be manually focused.I believe they're referring to the feel rather than the difficulty, when Canon lenses of this generation have a bit of use I find the focusing ring gets... gritty? for lack of a better word... due to sand or other dust between the ring and the body, they still focus fine and are perfectly serviceable however they loose the well damped silky smoothness and feel... rougher?
It's an amazing lens for the price, no doubt about that at all.
