Quick sharpness test, 70-300 vs 50-200 & EC20
Apr 14, 2010

Hi,

I made a very quick test to compare my 70-300 lens vs my new 50-200 for sharpness, also with an EC20 attached. The camera is an E620. It's a real dry "studio test" shooting structured wall paper from approximately 10 meters distance. Four 100% crops. All four shots used F8 and the same camera settings including anti-shock 7 secs, sharpness +2, live view autofocus, no pp done. EXIF info remains. Auto WB was used which seems to be handled differently with these two lenses.

There's a difference on pixel level, yes. Also in size and price...
Per

70-300 at 300 mm (after retrials as AF gave several really bad results)

50-200 with EC20 at 300 mm (or 316 to be exact)

70-300 at 200 mm

50-200 at 200 mm
