Done with Sony!  Believe it or not, I’ve reviewed every Sony DSLR lens.  Who knows when we’ll see anything new, maybe later in the year.  Of course I’ll be reviewing any new lenses or interesting cameras they do come out with.  In the meantime, I’ve got a couple of Minolta lenses to finish up on, and the Minolta 300mm …

The Sony 300mm F/2.8 SSM G review is now ready.  I got carried away with the product shots, so dial-up users be patient!  This lens turned in an overall stellar performance, and that should come as no surprise based on the cost.  You saw a small sample of what the lens is capable of if you visited this page

I wasted another part of my busy day to try and stop the incessant sob stories by non-believers of some results from this comp review, also see the 1/5/10 homepage entry.  Below are yet more crops between the Tamron and Sony 28-75mm lenses at 75mm, from the centers.  I did this seventh, (or eighth?), and believe me(!) final…
