I didi a comparison with my new to me Sigma 300 f4. I put it on my PZ-1 and sighted an object across my street, a roof top with side chimney and secondary chimney. I positioned the lens so that i had the chimney and roof top and all of the wood stove chimney in view. I then put it on the istD and i lost the wood stove chimney and a bit of the roof on that side. Not sure if its due to any magnification differences in the finders or, WYSIWYG. Dave > > > Shel Belinkoff mused: > > > > I'm just going to have to see this for myself.
