I have a pentax and I want to get an external flash for it so I can have a nice flash. Does anyone know of any. I have lenses and all the what not but I need a flash also does anyone know where I can get a 1600 mm lense? I have a 300mm and a 800mm lense I want a 1600mm.

How much are these things? Can I get them at a camera specialty store?

a 2x converter isn't usually more than a couple of hundred dollars; the big problem that you're going to face is lack of light since a 2x converter will take away at least 2 stops of light. If you're 800mm lens is, let's say, a f5.6 maximum aperture, with the 2x converter it will effectively turn into a f11 maximum aperture which means you'll need high speed film plus alot of light to shoot in...the better thing is to think about how to get yourself in closer to your subject than to try to get higher and higher powers of magnification...A few companies produce a pure 2000mm lens but they are extraordinarily expensive and have to be special ordered (they take a few months to make them!)
check the back of Popular Photography for used camera gear dealers, especially out of NY if you're interested in a flash

Just out of curiosity, what do you want to use a 1600mm lense for? If it's for climbing then I'm really curious because it seems like a bit of a pain to use for such a sport. I can think of some uses for it, but I used a doubled 200mm for a project and that was not something I could find alot of uses for... unless you're a voyeur.

one secret to getting closer to wildlife is familiarity: if you wear the same coloured clothing consistently & approach the bird on a regular basis it will cease to see you as a threat so that you can get fairly close over time. I spent quite a while shooting Bald Eagles & Great Blue Herons, both of which are fairly skitish birds, and I got better shots with a straight 200mm than with the 2x converter, in fact, I got rid of the 200mm and the 2x converter and got a fast (f2. 180mm auto focus lens that is very quiet and quite effective for wildlife photography. The game is all about patience & getting to know your subject whether it's a bird or a tree: spending time in nature helps us to understand what we're taking pictures of and how it fits into its environment.
Happy shooting!

I spend quite a bit of time trying and wearing the same clothes just ask my girlfriend she says I'm 'always after that damn bird.'
