Protar vs. Tessar

[Dan Fromm]

If both are uncoated the contrast will be higher with a Protar VII.

Interesting. Why?

come on Dan, air-glass surfaces!

Emil, Garrett, sorry, I misread post # 8 to say that a Protar VII has better contrast than a Dagor.

[E. von Hoegh]

See above.
And Dan, even if both lenses are coated - the Protar will have the edge regarding contrast and flare. A single coated Protar (or Dagor) is as good as a multicoated Plasmat, perhaps better, as far as flare goes.

It will, if the Protar is coated and the Dagor isn't.

"is there much (if any) difference between a Protar and Tessar?"

More important, will any difference between the Protar and the Tessar help or hinder your photographic vision?
Speed, coverage, sharpness (if sharpness is important) physical size, cost, coating(or at least the potentiality to minimize flare) and reliability of the shutter in any given lens are, for me, are more critical issues than the marketing hype of the design. YMMV, of course!
Aside from wanting a "back up" or say a different focal length, use what you've already got unless you've got a pressing reason for making a change.
My 2-cents anyway (and likely worth about a bit less than that)

Or if you want more contrast and sharpness, or want to see for yourself the difference, get the Protar.

Price, speed, ease of manufacture. Re this last, the more elements cemented, the more difficult centering them is.

Dan is of course correct!

But will an Artar between the eyes spark the imagination, or just dim the lights for a little while? Do the brass barrelled RD's still make a bigger impact than those in the newer Al barrels?
