Hi Everyone, Due to the little bit of success I saw with the tele conversion poll, I thought - why not buy a lens and try it out. B) Some of you voted and the top choice was a 50mm equivalent lens. With a little reading up on this forum and other great forums such as RF, FredM, SHuff, DP and this awesome review by millsart http://www.fredmiranda.com/forum/topic/1092508/0 I narrowed my search for the "right" lens. Then I fired up Ebay and found a nice circa 1988 x1.5 tele lens from RCA. [Lens Information] RCA X1.5 Tele Conversion Lens LX152A 77mm front thread 58mm rear thread 45mm (approx) rear pupil opening made in Japan [Qualitative Analysis] All around shooting is nice. Drop in f stop is not high at all , when I compensated with LR, most compensation was only as high as -0.3EV... which I think is pretty good. There is softening around the edges, especially when you go f4 or higher. At f2 and f2.8, the bokeh covers up the soft edges nicely. Lens vignetting -> present but not drastic, a bit artistic, easily corrected with LR [LX152A Equivalents] Olympus VF-KL2 RCA LX152A Sony VCL-1558A Kenko ??? - I know this exists, just don't have the part# Canon TC-DC58A - while not the same body, this lens does meet the requirements of a large front element and rear pupil opening, so I thought I'd throw it in [User Reviews of Specific Lenses Listed Above] Please login or register to view links Please login or register to view links Please login or register to view links [Summary] IMO, Lenses like this are best suited for any shots you would normally take between f2 and f2.8, unless you are willing to crop the center. I think portraits would look great with this lens Heavy and Big - ~350g with a 77mm front element -> just keep that in mind, it's no wcl-x100 50mm is doable - common Fuji let's see another adaptor lens In the next posts I'll show some image samples and what I hope they convey with respect to the lens.
