I've been perusing eBay, looking at picking up a new, compact enlarger. Actually came across 2 units that interest me very much. Both are made by 'Meopta'; the first is the Opemus 5a Medium-Format enlarger, and the second an Axomat 5a 35mm enlarger. I've always used just one enlarger for both 35mm/mf simply because it's what I had (back then, a Saunders/LPL 4550 VCCE). Nowadays I don't need anything that big, and the thought of having 2 enlargers, each setup with dedicated format-specific lenses and negative carriers is a welcomed prospect. I'm wondering if anyone has any experience using these (Czech-made, I believe) models, and what they thought of them. Also, as reflected in the subject, one of these units has what appear to be 'wings'; half-circle metal straps on either side of the lensboard. What on earth are these for anyway? Thanks so much!
