You can configure a search to look for listings that fall outside all of the predefined categories. You'll see thousands of listings, lots of listings that you can't figure out what is being sold, very few will be something you can use, and all from uninformed or deliberately ignorant sellers. But the items will be cheap, if you're willing to go to the trouble. That's how I like to shop eBay. Warning: a tolerant significant other is required.
I have both a split-prism and a viewfinder magnifier. The viewfinder magnifier helps but it won't knock you over dead with the difference. I would say it's 10-20% better.
Yeah, there's quite a few somewhat confusing and mysterious postings on eBay... over the years I've managed to glom a few deals because of that.
Thanks, guys, for the advice regarding MF. I might get the Pentax loupe, as it may improve my overall viewing pleasure... and if I don't find it worthwhile, I'll eBay it!
I did a comparison between the Osawa and my kit lens (DA L 18-55), both at 28mm, f/5.6. The lenses are comparably sharp in the center, with the Osawa a little softer at the edges. The Pentax lens is warmer and more contrasty.
Interestingly, the Osawa is only a little less sharp at f/2.8 than at f/5.6.
Right now, I'm looking for a cheap, fast 50mm, and that will satisfy my "cheap" LBA... for now.
