You wouldn't get that effect with a Thambar with that DOF. The effect diminishes as you close the aperture and actually the Thambar is a very good and sharp lens when closed down. 1 Link to post Share on other sites More sharing options...

Or, similar effect by breathing on the lens, shooting through a stocking etc. In the OP it is mentioned that there are two different lenses being used. Philip.

Pardon my complete and utter ignorance in 'The Ways of the Thambar', Ian!............ Actually I thought it looked like what I imagine an image shot with the Thambar wide-open and using the centre-spot filter might look like but, as I have had absolutely NO experience of using such a lens, I admit I was shooting in the dark! I'd love a shot of one for a day or 90. There has been no official clarification (as yet!) from pgk but I'm guessing that my Brillo-Pad guess was off-target, too...... Philip.

That's mainly because you live somewhere sunny! I don't encounter such problems here terribly often - and especially not today as it's pouring rain! Good fortune with your new lens!

pippy Posted June 10, 2020 Share #33 Â Posted June 10, 2020 (edited) Beautiful image, Ian! Very Painterly. Going OT for a second; Back at the start of the '80s I used to spend my holidays in my late-school years working in a small local camera shop. One of the regulars, a wonderful old gentleman who became a friend, knew I had a IIIa and in the course of our chats he mentioned that he had a Thambar (bought new!) and if I was at all interested...? I had never heard of the thing before and, when its rendering was duly described to me, I thanked him but, politely, refused the offer as I couldn't see how it would be of much use to me......

adan Posted June 10, 2020 Share #35 Â Posted June 10, 2020 I'll play. 90mm lens(es) Option 1: same lens, before and after removing/replacing lens when gear is cold-soaked, in high humidity. Fog condenses on rear element or sensor glass. Option 1a: swapping lenses (any) - same effect as (1) Option 2: any modern Leica 90mm (Summicron/Summarit/Elmarit-M/Macro - top) vs. Tele-Elmarit-M (in flare-prone light - i.e. bright sky just outside frame) Link to post Share on other sites More sharing options...
Ecar Posted June 10, 2020 Share #36 Â Posted June 10, 2020 I'll try a variation: same lens, picture taken from inside the car, 1st shot with side window down, second shot with window up (and some condensation on it). 1 Link to post Share on other sites More sharing options...
pippy Posted June 10, 2020 Share #37 Â Posted June 10, 2020 (edited) 90mm Tele-Elmar with hood clipped on; 90mm Tele-Elmarit-M without use of hood? Scrap that. You have already mentioned in post #8 that it isn't the hood. Hmmm... And it isn't just using a hat / anything-else as a makeshift shade? Were shutter-speed / aperture / ISO identical? Was one of the lenses a 1930's-era uncoated (obviously) 9cm f4 Elmar...(possibly with some fungus)? Philip. Edited June 10, 2020 by pippy Link to post Share on other sites More sharing options...

The fact that Paul wrote 'different' (note quotes) lens I think is a clue. Could it be the same physical lens set manually to a different coding on the M9? I'm guessing you are using your M9.

pgk Posted June 10, 2020 Author Share #40 Â Posted June 10, 2020 (edited) OK. You are getting close but I'll give one more 'clue'. The two shots are on two different copies of the same 90mm Leica MÂ lens. They were taken seconds apart and were given the same exposure and identical treatment when sorting them out for web use - the files have the same adjustments. The difference is down to the lenses.
