It is VERY good in my experience. I liked mine so much, I got another used one as spare :-) One is almost permanently on the A 300mm f/2.8 and the other is used with all the others. Works great on MF lenses, and is nice on an AF one to reduce the AF hunting area (focus limit). Quality seems quite good, can hardly see a difference between this 1.7 one and the two 1.4x or 2x L converters when used on the 300mm (and 510mm f/5 on the *istD is good for wildlife :-) Regards, JvW ------------------------------------------------------------------ Jan van Wijk; http://www.dfsee.com/gallery
