Hardware Blues
Hi! I'm a rank amateur when it comes to photography, using the point-and-shoot variety till now, but then I've decided to jump in with a bang. And there's the problem. I purchased an used set of camera & lenses on the net. The only problem is that it is without any documentation. I got them for a bargain because the guy who had inherited them could never figure out how to use them. And now I'm in the same boat.The camera is Olympus OM-10. I've figured out almost everything about it, but a few things.
1. In the outo mode how do I find out what settings are being set, in order to bracket them in the manual mode?
2. What is the 'R' button in front for?
3. There is a dial with 'CHECK','ON', 'OFF' AND 'SELF TIMER' on it, in that order. Whats that for? Now comes the fun part.
Its along with 5 lenses.
1. Olympus 50mm and 24 /F2,8. (what does that mean?)
2. 3 Tumron lenses, with Tumron BBAR MC along with Adaptell 2 witten on each of them. The lenses are a 2x teleconvertor, a 70-210 mm SP lens with 1:3.5 1:4/210. What do these ratios stand for?
A 35-70mm/3.5-4.5 lens. What are the numbers for?
Then there are 3 filters. They are Olympus Polarizer which is grey with no name/number on it, a simple skylight (1A) filter and a diamond filter with 6 facets from HOYA. And finally the piece of equiptment that has me totally foxed is the Flash. Its a Vivitar 4600 System flash with an DM/O mount (I think its called a mount. Its the part on the bottom which mounts on the shoe of the camera. Even though it has a pamphlet along with it I could not figure out how to use it. Another thing is that all these lenses are in a pretty neglected condition, with dust on and inside them. What cleaning material should I use on the lenses? I do plan to get them serviced, as soon as I can find a authorised dealer / competant repairman. Can you recommend any sites where I can find out about all the hardware that I have got? I know that I am asking a lot of questions, but even after reading all that I could find, I'm still not able to figure out these things. Please help. Thanks to all of you in advance. Love
Vipul.

User manuals for Olympus cameras can be downloaded for free from their www.olympusamerica.com site, specifically the OM-10 manual is at http://www.olympusamerica.com/files/Oly_OM10.pdf 24 f/2,8 is a 24mm lens (which gives a wide angle view) with maximum aperture of f/2.8. Camera lens aperture is given as a ratio of focal length to diameter. This can be expressed as f/2.8 or 1:2.8. I don't know what "BBAR" means, but "MC" is most likely "multi-coating", meaning the lens elements are coated to reduce reflections/flare. Adaptall 2 is Tamron's system for adapting the same basic lens to different camera makers' lens mounts. 70-210 refers to a variable focal length lens (zoom lens) of 70mm to 210mm (short to medium telephoto). 1:3.5 - 1:4/210 means the maximum aperture varies from f/3.5 (1:3.5) at 70mm to f/4 (1:4) at 210mm. Similarly, 35-70 f/3.5-4.5 is a 35mm (medium wide angle) to 70 mm (short telephoto) zoom lens with maximum aperture of f/3.5 to f/4.5. The flash code DM/O means Dedicated for Minolta or Olympus. It communicates with the camera to use the built-in through-the-lens (TTL) flash meter of the OM-10 to control flash exposure.

Oops, my mistake. The OM-10 does not have TTL flash capability.
