Sensor Damage In Flight?
MvMaltese posted a topic in Leica M9 / M-EHello, I know there have been a few words of caution on possible sensor damage when flying (gamma radiation causing sensors to fail, thus RED LINE issues) but was wondering if anyone has experienced this first hand? And if so what measures can be followed to protect from this potential damage? E.g. would a lead-lined film protection bag be useful for the camera body? Thanks, Mike
Has anyone tried bulb at 60 sec?
AnakChan posted a topic in Leica M (Type 240 / 262)Hi all, I'm curious if anyone has tried bulb mode with its max 60 sec exposure with their M240? I'm thinking of trying to take snapshots of my vacuum tube amps but I'm wondering if anyone who's tried it have noticed any sensor heat creeping. Is there any concern of heat damage to the sensor? Cheers.
Six Bit Sensor issue
essvaun posted a topic in Leica M (Type 240 / 262)Hi All, I've searched the forums on this but haven't found anything - if anyone can point me there please feel free, I don't wish to clog up the site unnecessarily. In cleaning up an M-P 240 for sale I've spotted this - the cover of the six bit sensor on the body has cracked. I use Zeiss lenses and never use the function so of course I've not picked up on anything. I've occasionally used friends Leica glass and it has worked but the last time was months ago and I have no idea when this happened, no memory of any fragments falling out etc. I clean the sensor with a blower whenever changing lenses but haven't seen anything unusual. Has anyone ever had this happen, and if so is it an easy repair or a 'return to Germany' ordeal (I'm in Australia, I'm sure their service is excellent but the tyranny of distance makes these things time consuming & costly from this part of the globe). Any thoughts appreciated.
Hi there. Couple of days ago I decided to try some LTM glass on my Leica MP and bought a new Fotodiox 50/75 adapter. While it worked perfectly I was surprised and mostly heart broken to see that the mid line of the lens mount had been scratched on my beloved camera which I saved for such a long time to buy. The scratch is superficial as far as I can see and on the 4,5,6 and 7 o'clock directions (The photo which I share on here doesn't do them justice. They are more visible than what looks like here). I didn't have time to develop my film so I cannot say if it damaged the mount on funtional level. But I want to learn your experiences with similar situations if you had any. I read that these things can happen even when you use native lenses on cameras but as far as I know for the last 9 months my Voigtlander 35mm f/2 Ultron didn't damage or let alone scratch the lens mount on my MP. I reattached my Voigtlander after experiencing this situation and shooting another roll of film with it to see if there is any problem. Is there a possibility that I damaged my camera functionally? Can my Voigtlander be attached to the lens mount securely and without further damage either to the lens mount or the lens itself? What are you thoughts on Fotodiox adapters? The adapter that I bought seems that it is made of a material that is not similar to the material that Leica uses on its mount. I would be grateful to read your thoughts. Thanks in advance.
Origin of negative scratches?
schattenundlicht posted a topic in DarkroomHi! Today I received a batch of negatives which I had processed and scanned at a dedicated b/w lab. Usually I do the scanning myself, but this time I needed some quick results to check the technical validity of some vintage cameras and I had little spare time available. These scans are low res jpeg and only substitute for contacts. I am thinking of re-entering the dark abodes of home-developing, especially after reviewing the result that I want to query this forum about. Seven rolls of TriX, TMax and HP5 from diffeent cameras (M3, IIIf, M7) came out fine, but one roll of film (TMax) from a 1934 IID shows peculiar scratches not typical of ones that I have seen or produced myself before. Since this is the only roll of film from this newly acquired camera that I have available (it is currently away for a focusing CLA), I would be particularly interested in whether it is a problem that might be related to the camera or whether it is related to film handling pre/during/post development, which I find more likely. Since I bought the camera from a respected dealer, he should be noticed of any problems soon as possible. The scratches start at #25 and continue until #36A, where the scratch line tapers off into the perforation. It is not a strictly parallel scratch like ones I have seen from damaged back plates or sloppy enveloping/ rolling and it is not continuous for all the way. I will post three example images. I hope diagnosis can be made from forum resolution. (1): #29, Inadvertent picture of my lens cap (idiot me ) (2): #32, Oyster bed, 300 million years old, today grounding a cottage, situated 600 Km from the nearest shoreline (3): #35, Casino, Wiesbaden, Germany Has anybody seen a scratch configuration like this before? Thanks! Kind regards, Mathias EDIT: By the way, the scratches are on the emulsion side.
schattenundlicht posted a topic in Leica M LensesAlthough the pro/ con discussion has been beaten to death in numerous forums, I feel obliged to urge my fellow Leicaists: 1. Use filters, use filters, use filters! 2. Better still: close hip bag properly 40 years of accident free photography passed by in an instant... M7 & Cron 50 V with Leica UV filter after full drop on asphalt. Body and lens elements seem to be miraculously undamaged (besides minor mark on retractable hood). Focusing is butter smooth and aperture clicks softly (lens and camera visited Wetzlar half a year ago for a full CLA). I still have to find a way to remove the filter, though, which seems cold-welded to the lens thread... Kind regards Mathias
