跟據色影無忌的同好所說，除了Mir-20外，其餘兩款的20mm超廣角均問題多多(最少出口貨是如此)，不值一試。

以下是一位海外用戶對Mir-47 K口版本的意見：

I've got a love-hate relationship with it. I love the focal length -- 20mm is a great focal length for playing with perspective, getting close-ups with lots of context, etc. The lens is sharp in the center and reasonably sharp overall when stopped down to about f/8; HOWEVER, the periphery gets downright blurry when the lens is wide open or even close to it. This makes the wider apertures almost useless, IMHO.

My particular lens also has some minor problems with its aperture linkage. It links up to most cameras just fine, but occasionally the aperture linkage will slip when mounted to my Zenit KM, and it almost always does this with my Ricoh XR-X 3PF. When this happens the camera's meter becomes useless because the camera can't track the lens's aperture setting.

FWIW, this is my second Mir-47K. The first one had the same peripheral blurriness wide open as the one I've got now and even worse aperture-linkage problems, so I returned it for an exchange.

I've also got a Mir-20 in Kiev-10/15 mount. It's not in 100% pristine shape, and my Kiev 15's meter is shot, so I don't use it much, but ignoring those issues, I think I prefer the Mir-20. It focuses closer and doesn't suffer from the same peripheral blurriness when wide open.

If the Mir-20 were available in K-mount, I'd probably buy one.

我都調在f8或是f11, 在0.5m以後通通都是清楚的
在snapshot的時候根本不用對焦, 構完圖趴擦砍下企就對了~
比AF更快~ 廣角的超長景深超好用!
