Polaroid SX-70: Can you attach lenses?

I love the mad professors of this community ahaha

People having ideas and building things in sheds - that's what made this country Great Britain!

@stevelmx5 Do you know what kind of lenses i'd be able to use with that frame on the SX-70?

Sorry I’ve got not idea. They look like accessory lenses for mobile phones, but it’s probably best contacting the guy who built it.

Well I remember (about 20 years back) a MP? quoting a Japanese report that half the inventions since 1945 were from the UK.

Can you experiment with free-lensing? Basically hold the lens of your choice in front of the camera and see what effect you get? Saves building frames etc just for a trial that may well fail,

No guarantees; free-lensing is normally done with no lens on the camera itself, AFAIK...

The problem will be that the standard SX70 lens will only be able to focus on something at the minimum focus distance, or further away. Putting another standard lens in front of it will more likely lead to a blurred image at best, although you should be a able to see that through the viewfinder and save wasting film testing it.

Any normal photographic lens intended to be used to produce an image will be be a converging (positive) lens, as is a close up lens. The effect will be the same in both cases - a reduced focusing distance. Which translates as a reduced focal length for the combination.

In principle a diverging lens should act in reverse, and increase the focal length.

Both require having flexibility in adjusting lens/film plane distance.
