I finally come around and clean my batch of Triotars 135, and was brushing up on history and some info. Now I have 4 of these. While 2 of them had their...
One other reason why I can think that they may go down to f32 or f45 is... were the triotars ever sold also as barrel lenses for use with 4x5 cameras? The...
Well since the triotar in 35mm had its own unique pre-set mount so its probably not a case of reusing anything. NOw the lens normally goes to f/22, and as I...
It had been reported that the earlier Asahiflex lenses could be modified for the new M42 by bushing the threads. This lens appears to be one of those. Bob ... ...
Thank you, Bob,
This is the only info that I have, probably made by tomioka in the 70's. I'm looking for a user opinion, Is a good lenses? What about bokeh...
Why does it remind me of the J-9? :D wink wink "Forgive your enemies-but only after you've given them a couple of swats." (tip #18 of A Cat's Little...
I've just bought a Chinon Memotron II (relabled as a Revueflex 5005) with the intention of getting into the M42 world and saving up for a fast portrait lens....
FP bulbs were hard to find in the 60's when dad taught me about them then.He uswe them with the speed graphic. They have to have a long buring time and iirc...
Perhaps other flashbulbs should work? I remember using AG-1 with the Pentax Spotmatic (flash plugged in FP) up to 1/500 sec. Jay "Forgive your enemies-but...
... the Pentax Spotmatic (flash plugged in FP) up to 1/500 sec. ... I don't think AG1 bulbs could have been successfully used with an FP connection unlessed at...
... That's what I initially thought too. I fired two or three exposures at 1/250 and 1/500 with AG-1 flash bulbs with a Pentax Spotmatic as a stunt. The...
Arent flashbulbs triggerred the instant the focal plane's travel offers lens-view (albiet however so brief) of the WHOLE frame?. I thought it wasnt always a...
(In reply) - Useful link on FP synch and SLR's: http://www.photozone.de/3Technology/flashtec5.htm " ... Standard flashbulbs (designed for "M" [20ms to peak...
I don't exactly understand what you mean :)... Flashbulbs are triggered (circuit closed) usually before the shutter opens. The delay is necessary so that the...
Was the fact that larger focal plane shutters take longer to complete their run compared to the small focal plane shutters in 35mm SLRs considered? I suppose...
Jay, I thought some long duration flash bulbs would work at SOME focal plane settings where the entire frame is exposed rather than a moving stripe of light...
(In reply) - It's been a LONGGGGG time since I fired a flashbulb, so you'd have to research that on Google. For the record, the Kiev- 60/Arax 645, which is an...
Yod If the flashbulb burns in its peak brightness for as long as it takes the shutter to complete its traverse, the frame will properly exposed. Many...
Well, it could work, depending upon the delay the individual camera provides at "FP" sync - the only flashbulb graph I have access to at the moment is for the...
(In reply) - This lens would be a Russian copy of the Zeiss Sonnar formula, and the Zeiss lens is acclaimed for both sharpness and bokeh. I have a P6-mount...
It's a great "tool" if you want soft-esque sort of shots... don't expect stellar sharpness. The most common version is the chrome Zenit M39 version (screw.mt),...
Yup. The original one is called the Sonnar 180/2.8 "olympia" because it was originally designed for the Berlin olympics of 1936(?). It had a removeable rear...
... One of my favorite lenses is my Helios 40-2, that I often use, believe it or not, wide open with extension tubes for even less DOF. I am wondering about...
Richard, when I find some time to take some photos w/ my 5D, I'll upload them. Do you really need something so long? A 180mm on your Sigma DSLR (I assume it is...
