Summitar

I was given a summitar to use as a lens cap but, after posting pics on the gallery of this site, the general consensus is that it is a remarkable lens. My qustion is: how does one know it the lens is a Summitar of an early version of the Summicron? Have people deliberately marked these lens to lessen flare? Please advise. Johne

Dear John,

The lens will be inscribed " Summitar* ".

What do you mean by "Have people deliberately marked these lens to lessen flare?"

Sincerely,

Justin

@All:
Summitar does not have the *
Serial number is 900582
It may be another urban legend but it seems I vaguely remember someone telling me that it helped this model to scratch the out edges on the back (like cleaning marks) to cut down flare.Johne

BTW, to see an ex&le from this lens, go to Travel in Gallery, one page back, and click on "Beautiful Ohio."

Dear John

According to the lens number list your Summitar was allocated its number in 1951, and as you have said is not a "probe" Summicron.

Nevertheless quite a good lens.

Enjoy it.

"~ it helped this model to scratch the out edges on the back (like cleaning marks) to cut down flare."

I have never heard that one before; In fact I suspect such treatment might increase flare.

Like Justin, I can't see how taking the black off would do other than increase flare. With a little care and thought about light sources in the picture area, the Summitar is a very good performer and has been among my favourite Leica lenses for many years. it provides an atmosphere that late more clinically perfect lenses can't match but is several steps ahead of the old Summar. If flare is concerning you the simple solution is to invest in the proper hood for the lens (a fantastic deep box-shape hood that folds flat when not in use). There are plenty on the net.

they have some for less than GBP30.

Thanks Andy and Justin.

The comment was based upon the idea that the path of focus narrows until it passes through the real element of the lens; therefore, the critical mass of that real element affecting the quality of the picture is toward the center of that element. The outer part of that lens element can be dulled without affecting the quality of the picture. At the time I thought it was questionable, but he claimed to be able to repair lens and I know I am woefully ignorant about physics. Johne
