Gosh, I've noticed the opposite. It wasn't long ago that the typical price for a Minolta 70-210 f4 was going for $140. Today, they've really dropped. I just checked ebay and they're selling for $50 or less in most cases. Heck, even last summer they were $80. Others have dropped by quite a bit as well. The ones I can't tell are the pro lenses because I wasn't in the market for them a year or two ago. My bet is that those dropped as well. Reason being the proliferation of the e-mount cameras. People love those A7 models and are ditching their a-mounts to get them. I, for one, don't mind that. A proliferation of a-mount cameras and lenses on the market works in my favor so I can upgrade for cheap. Read this guy's ad on CL in my area. The last line backs up my theory. He'll never sell it for the $675 asking price. It's going to be interesting seeing where Sony goes from here.
