- I like the 100mm/105mm focal length, personally I prefer it to 85mm.
This lens is wonderful in every respect except the f/5.6 widest aperture can be limiting. If using natural light and itâ€™s cloudy you have to plan ahead a bit and if itâ€™s plain dull you have to decide whether to use the lens with higher ISO or take something faster.
Apart from this the lens is a real pleasure to use.
Itâ€™s a pretty expensive lens but with patience itâ€™s possible to get it at a good deal.
