Mini update: I think the permanent rewind is a known issue, some component in the film rewinding mechanism is stuck.

Hi there, l've just gotten a Pentax 645NII medium format SLR. There's a C-S switch for autofocus mode - it's on the top left corner of the rear of the camera. C = continuous autofocus mode (quote p. 58 of the user manual: "If the shutter release button is held at the halfway position, the lens...

It'd be interesting to know if she wants arty and / or autofocus, and also different ranges. If she wants to photo anything / everything l am guessing that includes distant scenery > 100 metres away? In that case manual focus lens + adapter might not be viable, as she'd lose infinity focus...

Woohoo!!! Result! That's what i wanted. A name for it. I had no idea it was a T mount variant. ^^^ is that purely your view? I don't think the barrel ending is bespoke for the interchangeable mount that slots over it. As for the printer - trying to assimilate the info. I cannot have soggy...

Yes that's the sort of thing i want. Thanks. I'm not sure if it's the exact thing though. I had a Russian friend tell me it's called a "Swallows Tail" fit, but Google doesn't agree. This is the link he gave me: http://www.club-nikon.ru/forum/topic/91347-адаптер-кп-ан-иили-т2-nikon/...

The ring fits loosely. The grub screws do the real work of making the fit nice n tight. Because the lens will be mounted on a tripod it doesn't require a feat of engineering to make the fit. It's only seen on very long super tele (400mm+) lenses l think. It's not a one-off or rare, i've seen...

Oh heck noooo. The thing i tried to saw off turned out to actually be part of the lens. It's the 49mm diameter end of the lens. Its got a slight groove around the circumference. The groove is seen in cross section. The actual mount adaptors slot on over it. Then the 3 grub screws dig in via...

2 tests: try a bowl of fruit, and / or try with a timer instead of pressing the shoot button and so giving the camera a jolt. If that still gives you "unsharp" images: Test with another lens too. If you already have 18-55mm i'm guessing you'd want an autofocus telephoto zoom too, like circa...

I call this the Sigma Stigma. Obviously it's not just Sigma, a handful of brands dabbled with this rubberised skin in the 90s or thereabouts. Then 10 years later this happens. I've had limited success with isopropryl alcohol (surgical spirits, IPA - not to be confused with India Pale Ale). A...

Hi there, nope, it really is a 49mm smooth barrel. Smooth except it's got a slight trough around the circumference. The interchangeable lens mount slots over it, just like that. Not twisting, no screwing. Only then do you insert the tiny set screws, which go through the 3 evenly spaced holes...

(I don't know why i'm getting updates for this thread, i posted a remark about PPI insurance spammers but deleted it. But okay, this one's kind of photograph-ey:) The price of anything medium format, especially Hasselblad. One day i'll learn to make my own plates the cancer-free way and get a...

Hi there i removed a Canon FD mount. It screws onto the 49mm diameter rear end of the lens. Thing is, the mount doesn't screw into actual holes in the barrel. There are tiny set screws which dig into the rear end, and thus you add the new lens mount to the lens. You can't make this up! And...

Hi there, l'm sure l discussed this before, but previously the thread died when i attacked the rear of my lens with a hacksaw, thinking the smoth terminal was removable. Well, it isn't. It's 49mm wide and the actual mounting surface needs to slot onto it, with tiny screws securing it to that...

Right so you're here with no previous contact with me - or so you'd like it to seem - and your mission is to debunk my form, my format, my style rather than reply to the topic. This is disappointing, you're not here to enjoy the thread but go on, l want you to have the last word, before the iggy...

Whereas this news item makes sense ... ?
