借問聲 SE21/3.4 用原庄 leica e46 filter 會有黑角嗎? 定還是用 B+W Nano 好? 唔該.

21/3.4A the best, but I think no silver chrome.

Great picture with great color

Like all wideangles (especially superwides), 21/3.4A has some vignetting.  Stopping down alleviates but doesn't entirely eliminate the problem.  Stop down too much and there's another problem with chromatic abberation.

I have not yet made a comparison between Leica E46 UV and B+W XS-pro super slim MRC, but I suspect the slimmer the UV filter the lesser the vignetting.
