… but there’s a cost for that which I’m not ready to pay for: what we gain in overall contrast and apparent sharpness, we loose it in microcontrast and it badly affects the rendition of materials and contours. I have no other word to describe the Planar effect but “plastic”: everything looks like plastic; it is like shooting in a Barbie world … life in plastic, not so fantastic. Call me crazy, but that’s how my shots look like to me. I scanned in average and high resolution (1200/2400/4800 dpi), I tried different scanner settings, different softwares, I wet printed … always the same feeling about my pictures.
Besides, there’s something even more troubling, visible at 1200 dpi and obvious at 2400/4800: the lens is not that sharp, at least it is less sharp than my old rigid Summicron. It gives the feeling of sharpness because it is very contrasty, but it “squeezes” micro-contrasts and some details (skin contours for instance) are smoothed out, not to say erased. This is not visible on internet sized pictures but it’s there. This explains the “plastic” effect I was mentioning above.
So I guess that is what we get from a modern design lens, and the Planar ZM exemplifies perfectly modern optical features. If the Planar ZM is better than the current Summicron (I trust people who claim this), then the current Summicron is worse than the rigid or DR Summicron; I would add it is worse than the Summitar and other classic lens. The issue of the handling of micro-contrasts is of major importance IMHO, and in this respect I think that modern lenses as the Planar ZM are not so good. They are very contrasty overall, but lack subtlety. I guess, I only guess, that the Summilux asph and the Noctilux are free from this shortcoming; and I guess that’s why they’re so expensive.
In the end, if I add to buy again a modern lens, I think the Nokton asph 50/1.5 is of better value for the money; it shows all the modern optical features but I prefer its rendition to the Planar. So I came to this conclusion: take the Nokton asph if you can’t afford a Summilux asph. (I owned once the Nokton, so I know the lens).
I don’t expect you guys agree with me, but I’m looking forward to your opinion on the subject.
Cheers,
Marc
PS: so far, the only lens that seems perfect to me, sharp, contrasty, with a nice bokeh, with beautiful contours/relief rendition … it is the Planar … but not the ZM … the 75/3.5 for Rolleiflex. Any idea of its equivalent for 35mm RF?
