Re: DA 55-300 vs DA* 300 f4

Try looking at Photozone's test instead, both real world images and MTF50 charts.

The 55-300 can only reach the Excellent level in the MTF50 test at 200mm and below. It barely gets a Very Good in the center wide open beyond that including at 300mm. And at 300mm the edges are barely even Good until you stop down at least 1-2 stops, and that was on a K10D. The DA 300/4 was tested on the tougher K-5 and it reached almost to the Excellent level across the board at F4 even and did reach that level at F5.6 in the center. The 55-300 scored a 2.5-3 star rating while the DA300 got a 3.5-4 star rating.  The only zoom I know that can reach the performance level of the DA 300/4 at 300mm is the discontinued Sigma 100-300/4 EX, a lens I have been using for years.
