Sigma 100-400 mm f/5-6.3 DG DN OS Contemporary X Mount

I needed a long lens for a specific shoot, this lens handled the job really well. It’s incredibly sharp with snappy focus. It’s a very good lens at any price.

I have only tested so so far. happy with the results'

Good Points: Fast silent autofocus with a good sharpness and bokeh, fits in a camera bag nicely (billingham or Domke F2) Improvement Points: AFL button will not work on Leica SL2-s or SL2, wish it came with tripod mount.

Good Points: Great carry anywhere tele zoom. Not too heavy. Great image quality (for me). Improvement Points: Include the tripod mount ring in with the lens for free.

Good Points: Robust and excellent zoom range Improvement Points: Tripod collar needed to be purchased separately and is too tight fitting. Would have preferred if it was supplied with the lens as per Canon or Nikon telescopic lenses.
