Cobra Auto 210
Posted in Flash Photography
Just to add to an earlier post in this thread - I was interested to see if I could use my Auto 210 on my Canon EOS600D, so I brought it to work today and measured the trigger voltage..... I got 234V!! So, needless to say, it will be going NOWHERE near the hotshoe on the Canon!
Cobra Auto 210
Posted in Flash Photography
Hey thanks George and John - that's very helpful. Sorry for being tardy with a response. I kind of assumed that I'd get an email or something when this thread updates, so only just seen your posts.... As George has spotted I use film (on Pentax anyway - also have an EOS600D but not using the Cobra on that as it might kill it), so changing the film is not an option for odd shots. Doing a bit of Googling leads me to believe the GN for the Cobra may be 21, so at ISO100, with a subject 3m away I would use ~f/7, right? So what happens if I have ISO400 film in the camera in that case? Would I then just stop down two stops as the 400 film is 4x as sensitive as 100? I think what I need to do is get some cheap film and have a play about! Many thanks Mark
Baseplate screws for K1000?
Posted in Pentax Film SLR Cameras
Thanks John. I actually managed to get one from Jem at The Real Camera Shop in Manchester. As I had taken my K1000 in there a few months ago to have the light seals checked I can't believe I didn't think of asking Jem first! Supplied and shipped all the way to Singapore for just £4!
Baseplate screws for K1000?
Posted in Pentax Film SLR Cameras
Hi, I have a K1000 (think its a HK version), but unfortunately I've lost one of the screws from the baseplate. The base has three screws in it - two larger and one smaller (next to the battery cover). Does anyone know where I can get a new screw from please? Or does anyone happen to know the exact specs of the screw so I can track down a replacement? Thanks Mark
Cobra Auto 210
Posted in Flash Photography
Can anyone please explain to me how to use one of these Cobra Auto210s? I got one with my K1000 off eBay (the flash was an unexpected bonus) but there is no manual with it. As far as I can see, you do this: - Set the ISO/ASA of the film with the slider - Choose an aperture, shown by either the red or blue markers under the slider that corresponds to the desired distance range, and set the switch on the front to either red or blue to match - OR, Set M on the front switch to just get full power (no idea how far that will illuminate) - Shoot But what happens if I want to use a different aperture? Is that not possible? Am I constrained to the two apertures the flash is suggesting? If anyone has a manual they'd be willing to scan and email to me I'd be muchly grateful! Thanks Mark
