ZEISS Ikon Biogon T ZM 2.8/21 Super Wide-Angle Camera Lens for Leica M-Mount Rangefinder Cameras, Black

Zeiss quality...

I recently purchased this item and was a bit dubious about my ability to use it properly. I can honestly relate that i am greatly pleased with this lens and have taken pictures that show detail very well and that show colors that are outstanding. It is every bit as good as I was told it would be. I am hopeful that I will have the pleasure of using it for many years.

What's so surprisingly good about the Zeiss 21mm ZM lens is its sharpness across the frame. It's astonishing, honestly, to see how much sharpness you get within an image. I can pixel-peep my images from my M-E and see barely any distortion or fudging of details. Wide-open, it's even somewhat fast enough for available light photography. I wouldn't quite drop it under 1/25th, though.It's worth noting, however, that these lenses do not come with a 21mm finder. Zeiss offers one at considerable price, but I recommend the cheaper Voigtlander 21mm finders or Leica's old 'SBKOO' 21mm chrome finder for the hotshoe. You can get the latter for 250-ish USD used at the time of writing. Composing without one with a .72 / .85 finder is nearly hopeless.
