A1 Dimage rubber eye piece for viewfinder? - Konica Minolta DiMAGE A1 Digital Camera

I've had the same problem. You simply can't get them new, but you can salvage them from the many scrap A1's and A2's which have suffered circuit board failures. Take care as you peel it off the old camera though as it's very easy to tear. Best reglued with a few very carefully applied smears of superglue. If you want your camera to last, then afterwards use a bit of double-sided foam based sticky pad to secure the viewfinder in the down position: leave it free to move and it WILL fail (I'm amazed it hasn't done so already). Basically there's a poor design which causes the flexible circuit board to crack and once it goes it usually cannot be repaired.

A whole scrap camera is usually quite cheap on auction websites, but ask questions to ensure that the item is supplied to you before the previous owner has harvested all the all the useful bits, such as batteries and caps.

There is an ebay seller in the USA who sells an alternative eyecup which will just about fit, but it interferes with the viewfinder's ability to lay flat and also looks very amateurishly applied afterwards. The original item is by far the best.

Hope this helps, please take a moment to rate my answer.
