Oldest Lens

I have some Cooke Triplets, a few Dallmeyers, some Dagors etc but they're not for these cameras.... But they're old....

 

I know...I know.... Pout...sob

 

That's a really nice image. Good old lens, that is. There's a few on ebay at the moment.

 

The best I can do is a 1935 Elmar and a 1935 Summar.

 

See post number 330. https://www.mu-43.com/f40/adapted-lens-image-thread-302/index22.html Amongst those I used my 1936 Elmar

This is my 1935 Elmar (cropped by half)

 

Quite interesting what that focus does to the spoon! Looks different then most focuses these days. :]

 

I suspect that some of the bokeh (out of focus) effects of these old lenses will be influenced by the number of scratches/blemishes on the lens elements.

The older Leica lenses have their own characters. This picture shows, I think, the characteristic 'Summitar glow' (1942 lens)



This is with a 1935 Summar

 

For those wishing to try the Summitar or Summar don't be put off too much by the mention of haze. It is fairly easy to unscrew the front elements and then clean the inner surface of the lenses with a quality cleaning system. I have done this quite successfully using a Carl Zeiss cleaning kit.The thing to watch out for are those that have been coated on the outer surface, this coating can be fragile.

I'm sure Brian S will be able to offer more experienced advice on these old lenses.

 

I have a Nickel Summar that is early, and have used it on the M8, and an even older Elmar. I have a Black-Faced 1931 5cm F2.8 Tessar in Contax mount, going by the SN it was one of the first. That is my oldest interchangeable lens for 35mm. I can use it with the Amedeo adapter on the EP2. Have not done so yet. My oldest Nikkor is a 1948 5cm F2 collapsible in Leica Mount.

Still some sun outside...

 

Nice, I have an old Hektor from 1938 but have not really used it enough, too many lenses competing with it... I always liked the thought of playing with an old Summitar or Summar, but prices for the good ones are pretty high for my standards. I'm not exactly sure how old my uncoated Cooke Kinic 25/1.5 c-mount is but that might be older than the Hektor.

I have a 1957 Hektor 13.5cm . I've only tried it a couple of times on the G1. The lens is pretty sharp but as it is an effective '270mm' it is difficult to hand hold.

I'll fish it out this weekend and if the weather stays fair I'll take a few test shots.

I suspect the Elmar in the 300K SN range was coated after being built. I looked at my Elmar in the 200K SN range, marked in cm. Same with the post-war lens in the 640K range, coated but marked in cm.

On the early Elmar marked in "mm", check the aperture scale and the DOF scale. They should both be the old F-Stop progression.

This lens is converted to Leica Thread Mount using a Russian J-3 focus mount.
