<p>Roger. Those converters are available on eBay for about $75 each. <br> <br />Based on various calculators and reading I've done over the last few weeks, I think the magnification would be as follows when paired with a 50mm Canon FD macro:</p> <ol> <li>The bellows can go up to 175mm, which combined with my extension tubes would add up to about 250mm. That would yield 5.5x magnification, and I'd have to open up around 5.5 stops to compensate for light loss.</li> <li>The tubes, however, would be 450mm when stacked. This would yield 9.5x magnification, at a cost of about 7 stops.</li> </ol> <p>Since I haven't done much macro, I'm not sure what these magnifications are good for. That's the next thing I'll start reading about.</p> <p> </p>

<p>Wow - stunning work. I need to spend more time around here. </p> <p>I really need to learn how to up my scanning game. My B&W scans with my Nikon CoolScan V are plagued with dust and soft edges. The work you've posted here is pristine!</p>

<p>What kind of magnification would I get using a 50mm Canon FD 1.4, the extension tubes, and the converters?</p> <p> </p>

<p>I should note - I'd be using these with an older F1. The link on mir.com.my shows this: http://www.mir.com.my/rb/photography/hardwares/classics/canonf1/html/macro/macro.htm</p>

<p>Well, I think I just answered my question. I found a good price on a 50mm f1.2 L, on sale for today only, so I grabbed it. I'll be selling both my 55mm f1.2 and my 50mm f1.2 (both non-aspherical) to pay for it.</p> <p>That said, let this thread serve as warning to anyone shopping for supposed L lenses. Know the markings you expect up-front. Don't take a chance if anything is off. There are fakes out there.</p>

<p>They screw-mount onto the Canon rangefinders, which I believe are the same as the Leica L39 mount.<br> <br />@ Jeff - I'll keep you in mind if I sell them, which is likely. First I want to figure out what they can or can't do.</p>

<p>Thing is, I already have a nFD 50mm f1.4 and an older 55mm f1.2 and now this nFD 50mm f1.2. My plan was to sell the 55mm, keep the 50mm f1.4, and add the 50mm f1.2 L to my kit.<br> <br />I guess I could sell the 55 and keep the lighter 50mm f1.2, and stop thinking about aspherical lenses for a while.</p>

<p>I've just acquired some gear. The macro gear in particular is interesting to me, as I've been looking to take some bug and nature macros. I've already got a 100mm f/4 macro and a 50mm extension tube for 1:1 that I plan to use for that. I would kind of like to do more extreme magnification (2-10x) too, just for kicks, but I have no specific plans there.<br> <br />So, on to the gear. You can see all the photos in imgur: http://imgur.com/a/OETx4</p> <p>First up, a set of <strong>Canon screw-mount extension tubes</strong>, 100mm, 150mm, and 200mm. They appear to be part of the set described here: http://www.mir.com.my/rb/photography/hardwares/classics/canonf1/html/macro/macro.htm and pictured here: http://www.mir.com.my/rb/photography/hardwares/classics/canonf1/html/macro/photomacro.htm. To use them would require a Lens Converter A and Lens Converter B, about $75 each on ebay.<br> How do I determine the magnification they provide? How would one light a subject at the end of such long tubes? <br> I'm inclined to sell this kit, and buy an auto-bellows in the future if I really want to do extreme macro / microphotography.</p> <p>Next up, a <strong>Canon Macro Coupler FL</strong> & <strong>Macro Hood</strong>. I already have the 50mm f1.4 breech lock lens this goes with. What magnification would one get from reversing the old breech lock 50mm? With a 50mm extension? <br> Given that I already have a 100mm f4 macro & extension, I don't know what this would add to my gear. I'm inclined to sell it along with the 50mm f1.4.</p> <p>On the imgur link, you'll also see a few other items. There's a Kodak spiral-bound datasheet for a bunch of 80s-era film, a set of film data sheet cards, a polycontrast filter computer, and a set of spotting colors. I'm inclined to recycle this stuff, but if there's anything useful here or any data that should be preserved, do let me know and I'll scan first. I am relying on the internet to help me figure out what is junk.</p> <p> </p><div></div>

<p>I just bought this lens from a local seller on Craigslist. The seller got it from a garage/estate sale with a bunch of other FD gear, and had used it on a Sony mirrorless setup.</p> <p>When I saw the lens in person, I noticed it didn't have the red L on the front ring, but it did have a red ring around the barrel. It appeared functional in good condition. The seller claimed ignorance on whether it was an aspherical L lens or not. In the end, I decided to take a chance on it. It was priced a little high for a standard 50mm f1.2 and a little low for an aspherical lens.</p> <p>Now, on closer inspection, I think it's a non-L with a counterfeit red ring. I weighed it on a gram scale. This lens, without caps, weighs 310g. </p> <p>Mir.com.my says the aspherical version weighs 380g while the non-L weighs 315g.</p> <p>I never considered I'd run into faked lenses, but I can see how this would have been a common scam back in the day.</p> <p>So what should I do with it now? In a bout of gear acquisition syndrome, I decided I really wanted an aspherical 50mm f1.2 to pair with my F1 for street shots. My fake L seems to be functional, though I haven't processed any of the film I've run through it yet. I already own a non-aspherical 55mm f1.2 that planned to sell.<br> <br />I'm inclined to remove the red ring, sell both my 50 and 55mm/f1.2s and keep shopping for a proper aspherical 50mm. </p> <p>Pics on Imgur: http://imgur.com/a/DMMBe</p> <p><img src="http://imgur.com/tPY72Sy" alt="" /></p> <p><img src="http://imgur.com/maIT9BO" alt="" /></p> <p><img src="http://imgur.com/0FNrFK2" alt="" /></p> <p><img src="http://imgur.com/9hsFuVK" alt="" /></p> <p> </p><div></div>
