Well, cheap is relative. This one will get the job done beautifully on the 5X7 format and do it for under $200 bucks. f6.3 means it's small enough to fit on your Technica lens boards! Glass is beautiful for it's age. Look hard enough you may find a sleak on the back. Inconsequential. I'm about 90% positive it's a Bausch & Lomb projection lens but there isn't a mark or a clue. It's a petzval. It's not going to swirl as easy as the f3.5 ones, but it also isn't gonna set you back 2 large. Haven't we about worn out the swirl craze in any case. This will make some very very classy portraits for you on either 4X5 or 5X7 format. Tack sharp center, luscious bokeh as you move away from center point. That's what petzval's do. $195 + shipping. PayPal is available.
