very good fully open some CAs
The SMC DA* 200 F2.8 comes fully sealed and lightweighted at 850g. It is very handy. the silent focus works at supreme level, it is reliable and quite fast. this is the only option to go for wildlife. mechanical focus systems are normally not usable for wildlife photography except in the ZOO or in commercial Parks. there the animals mostly turn away in a disgusted manner from any two legged individual or are simply bored of humans. In almost real situations only silent focus is doing its job whithout scaring the little beeings off. So SDM is a must have.
The Image Quality:
Above F4.0 the IQ is very good and improves a bit when stepped down to F8.0. In this range the sharpness ist very good all over the frame. the colors are reproduced reliable and authentic.
All apertures slower than F4.0/F3.5 produce a soft image and fully open chromatic abberations are visible even when the image is not zoomed to a 1:1 size. But F2.8 is a valuable option for low light conditions or art shots.
The lens might be a bit pricy. What the customer gets is a high quality fine build handy and good working lens.
