I am interested in your opinions on the old OM Zuiko zooms (not the new digital ones). I keep coming across negative opinions on the Zuiko zooms such as "stick with the primes stay away from the zooms". I cannot understand comments like this as I have never found any of the zooms to be poor performers. I own an Olympus 35-70mm F4 and a 85-250mm F5. These are old designs from the 70s but I have found them to be excellent. The 85-250 is equally sharp as any of my prime Zuikos in my opinion. I have compared the 85-250 to the 200 F4 when set to their widest apertures and stopped down a bit. I have always been pleased with the performance of my 200 F4, but the zoom seems to be a tad sharper with more contrast. At the 85mm end it is suberb. My 35-70 is no slouch either. I have not done direct comparison with primes but slides I have shot with this lens have always been crisp with high contrast. I had a 12x18'' print made from this lens when set to the 35mm end and it is tack sharp. The one flaw I can find with this lens is noticable barrel distortion at the 35mm end (Proberly no worse that some modern digital zooms manufactured today). I used to own a 35-70mm F3.5-4.5 which I now regret selling, as this was an excellent lens too, proberly better that the 35- 70 F4 being a more modern design. I have also used a 75-150mm and seen slides and prints from my brothers 28-48mm and 65-200mm F4. They seem to be fine lenses as well. What do you think of the OM Zuiko zooms? Are they underated?
