Sorry to resurrect an old thread, but these photos are fabulous. Has anyone compared this lens to the Oly 35-70mm 3.6? If so, what's the verdict?
Very timely, testing in the pipeline at the moment!
I returned the Zuiko 35-70/3.6 for flaring issues, especially with veiling. See below.
Just received a mint, Rokkor (macro version) today and it seems the flaring is also bad, (but not veiling flare). So bad in fact that I'm convinced there must be an element out of place, see third picture, (Unless it could be an adapter issue?) However, for sharpness and clarity the Rokkor wins hands down, it really gives the Contax 35-70/3.4 a very close run for its money! However, unless I can track the flare to an adapter issue, I'll be returning this, otherwise mint copy, and trying another.
These are on my Sony A7, without lens hoods, and the adapters used are from the New VA series by Pixco, which I've been very pleased with for the price. I've used modeller's matte black enamel inside, to reduce internal reflections. I've also taped over the lens/adapter mount interface with black tape, where I've had some issues.
My standard flare test,(not for resolution!), of gable end of building, sky just out of shot on each side. (Sun behind building, flare from sky alone!)
First, the Zuiko @ 50mm F8 (worst FL for flare on all tested)
Second the Rokkor @50mm F8
Third the Rokkor at same setting closer up to wall and angled up!
Finally the Contax C/Y 35-70/3.4 @50mm F8 as my "Standard" (The diminutive Zuiko 35-70/3.5-4.5 is similar and the Zuiko 35-105/3.5-4.5 outperforms the Contax here, showing hardly any flare!)
EDIT: Since doing this test, I've been adding flocking inside the Rokkor adapter. I can't retest on the above for a few days, but certainly against a light, the flare seems much reduced. I may need to re-evaluate others now. However I'm fairly sure that what I said about the Zuiko F3.6 is correct, as I've tried others on that adapter without the same veiling flare problem.
