You Can't Buy This Lens... Auto-Aperture Pentax K Mount version Sony a5000 (with K-mount manual adapter) ... As far as I know, there may only have been a handful of units of this lens actually made. As for wanting to buy it, it is debatable whether you would. Here is the story: Many years ago, in the film camera days, when Black's Cameras was a big photography store chain in the Province of Ontario, Canada, the company used to sell some store brand products. The "Magnicon" lenses were one of the brands that the store used. Some of the lenses were very good. They were roughly as good as the Soligor line. This lens, however, was not well liked. I knew a photographer that tried out one of this model lens and was disappointed. I cannot recall everything I was told, but the word "soft" was prominent. When that one word was uttered, I basically stopped listening. It is all I needed. Back then, if you had a soft lens there was nothing that could be done about it. Today things are a bit different. I still would not want this lens if I was using a "Full size sensor" camera, but my equipment is at the opposite end of the scale. The largest sensor I have is an APS-C on my Sony a5000. So that makes a number of old "budget" zooms interesting. Why? Because many of them were not bad in the center, but fell apart badly off-axis. But since I am using a crop sensor, I am not using the outer reaches of the image area. So if the center is sharp and it does not fall off too much, say within 2/3 of the way out to the corner, then I might have a pretty good lens. The interesting thing is that this model lens did not show up in "many" of the Black's stores. The smaller stores never had them at all, and the only store I saw one in was the "Yorkdale" store, which was one of the stores with the highest sales volumes. There were only about three other stores here I would expect this lens to have shown up. If this was a test market situation, there is no telling how few of this lens model were made. It is possible that this is literally the only unit that was ever sold. Moreover, a previous owner etched his name in the barrel, and I think I might even know who it was. Anyway, I found it in the used section of a camera store for around $80 Cdn, and decided to buy it. These photos were from my second outing with this lens, and in general, I am pleased with the result. From a mechanical standpoint, it operates smoothly. The Macro focus only works at the far telephoto end, which is unusual, and it is not locked out, so when you zoom in, you might not realize of you are focussing in the Macro zone, and that can be a minor irritation when you want to zoom back out and cannot until you un-Macro-focus it. I will not be posting full "unprocessed" images. I will post a few "detail" cropped files that are not altered (except for the crop). But since I am fairly sure nobody will find this lens to buy, even used, unless I decide to sell mine, this is hardly a loss. For this image set, most of the files started under-exposed, and I brought them up. There is only 1 which I liked at normal exposure. In all cases, I took the pictures with RAW+JPEG, but I have only used the JPEGs. Since I am mostly not posting "full size" files (except for the "detail" files). It will not make a difference. Focal Lengths used: unknown, mostly long-end (maybe 40 - 135mm?). Apertures used: roughly 4.0 (wide open) to 8.0. Mainly 8.0 "DSC00140.JPG" (probably ~F4) Partial EXIF 1/125 sec, ISO-200 (EV -1 step) Brightness 0.06796875 8.21 MB SmartFix Overall 28 Shadows -10 Highlights 20 Sat 14 Focus 37 Black 8 White 12 - I would have preferred more distinct lighting to separate the main subject from the background.
