Attaching SLR lens to A70

[Mr-Wong]

I have a couple older Nikon zoom lenses with the typical SLR bayonet connection. Is there some way I can attach them to my A70? I looked for a 52mm - bayonet adapter without much luck earlier.

I wonder... That would be cool... I have a 500mm f/8 sitting here unused. I recall seeing those adapters. I might even have one, but I think your best bet to find one is photostores with lots of used equipment. Might have one tucked away. I wouldn't expect anything from a mall shop. Perhaps Ebay?

The A70 could likely be destroyed by the weight of a large lens. (I don't think the 500 lens had a tripod mount.)

As far as I know, the lens mount is only for add-on lenses, like a tele or wideangle converter, already designed to be coupled to an existing lens, not for "proper" lenses like a SLR one, designed to focus in the film (or sensor) focal plane.

Thanks for your input. GF has a point that the innermost glass and the focal plane are supposed to be a bit apart, like the innards of an SLR. If I was to do this though, I would definately have the A70 to 3.0x when the lens was attached, so a set distance would be attainable. I agree that it would be a precarious setup, and probably would only use it in quite calm and controlled situations to avoid too much stress on the equipment.

I tried wolf camera's live chat help yesterday and posed the question to one of their "technical representatives." All I got after about 20 minutes of the representative "researching" was that I should buy the LA-DC52C adapter, and that my A/C adapter plugs into the side of the camera. hehehe.

The problem isn't only the distance, but the light paths. To use a lens over other lens is like using the same lens directly over your eye. Try an experiment. Put your lens at "focal plane" distance of your eye, and you still has nothing to see thru the lens, except you are using a "SLR focusing screen" like traslucid glass or paper betwen the lens and with the eye focusing in the screen. If you don't have a SLR camera, try to put all the ensemble in a dark tube, or the ambient light will be more intense than the screen image, or put a traslucent paper (like a negative archive sheet) in the camera focal plane with the back open, and a long shutter or bulb setting, and point to a bright light in a dark room. You will see the imaging forming there, but if you remove the paper, all you will see is the aperture blades closing during the shoot.
