Olympus Zuiko 70-300mm f/4.0-5.6 ED Lens – Review:
First I got only mediocre results from this les then I decided to to a quick resolution chart test. And I couldn’t believe my eyes that how sharp it is, at least in a studio. Let me provide you my results.
Tested on an Evolt E-510. Please note that the horizontal absolute resolution limit of E-510 is just 2100 LPH due to the famous DPReview.com. Anything sharper won’t reflect here.
Here you go.
70mm F/4: 2100 LPH. F/4~up, 2100+ LPH.
150mm F/4.6 1900 LPH; F5.6~up 2100 LPH.
220mm F/?? didn’t test; F/7.1~up 1950+ LPH.
300mm F/5.6 1750+ LPH; F/8~up 1850+ LPH.
“+” means unsure but at least.
Note I am just trying to measure the ‘absolute resolution’ here which means the ‘extinction resolution’ go even higher (usually 250 LPH higher).
Wow! This means from 70-150mm (that is 140-300mm equivalent) the lens resolution is beyond the current 4/3 cameras! From 150-300mm (that is 300mm-600mm equivalent) this lens pretty much scratches E-510’s limits.
On the downside. I do find the focus to be very slow, especially in low light where it can be erratic. It is frustrating sometimes. So my medicore results came from the focus. Whenever I get the focus right, I get tack sharp results. But it is not easy with this lens. Be prepared to use this lens only in bright light.
How much did I pay for this lens? 360 dollars, not 3600 dollars! I know its limit but with some very careful work I can get some professional level results on my wildlife shots.
