Please all stop buying legacy lenses

Price have been steadily rising for sure for MF lens... but it's reaching it's saturation points, with 50 1.8 AF going for 100 bucks, there's no reason for the older 50 1.8 MF to go anywhere near 50 (they are floating around 20-30 now for bad mounts such as MD, AR, FD), the M42 mount have always hold a high price, because anyone under the sun can mount them (except for nikon), so that takumar you're talking about is just experiencing the hike due to more user using DSLR more so than the mirrorless mob grabbing everything in sight.

At the same time, we live off alpha mounts, I own a canon 20D, and trying to find a 1/2 decent lens without selling my liver on that system is nearly impossible. cheapest "decent" lens is the 55-250 IS, and that runs at 130-140 easily, the rest is normally very high price for average quality compare to the alpha system (most of them has no IS if you're buying older lens, new one with IS is 300 minimum)... so MF focus lens for us is less appealing compare to canon/nikon folks.
