All the latest generation, automated hematology analyzers have a flag for fragmented red cells (FRC), and some of them also provide methods for an automated FRC count on EDTA‐anticoagulated blood samples, through the measurement of forward scatter and the intensity of fluorescence (Jiang et al., 2001; Abe et al., 2009) or 2‐dimensional.

Japan' imprinted around the rim, while version two has 'CANON CAMERA CO., Inc. LENS MADE IN JAPAN' imprinted. According to Canon collector Peter Kitchingman's site www.canonrangefinder.com and his recent book, version one was produced from 1956-1960, while version two was produced 1961-1967. Peter has confirmed that 43,675 of the 50mm f/1.2 lenses were produced - with about 24,000 being of version one and the remaining being of version two. Serial numbers run from 10050 to 56440, again according to Kitchingman. Version one came with a 57mm satin chrome lens cap and a 40mm satin chrome rear cap, while version two came with a 57mm black plastic lens cap and a 40mm black plastic rear cap.
While the 50mm f/1.2 lens had a standard black and satin chrome finish, a small amount of 'black' versions of this lens were produced as an option for purchasers of the 'all-black' Canon Rangefinder camera bodies. The aperture ring and distance scale was finished in black rather than the normal chrome finish. Scroll down the page for an image of this variant. You can read more about the 'black' version here: This lens has some unique crazy swirly bokeh that is somewhat similar to the canon 50/0.95 aka the 'dream lens.' This is because the formulation of this lens is exactly the same as the 50/0.95 except with smaller glass elements making it a f1.2 instead of the 0.95 huge light gatherer. Invisor 3 13 inch.

Condition I bought this lens off ebay from Photo Village in NYC. My lens is marked 'CANON CAMERA CO. Which mean this the 1st version of the lens produced from 1956-1960.
It is also marked with an ' ' ('Exchange Post') which means it was for sale at US Military bases in Japan. Supposedly, this makes the lens more collectible. ' wasn't mentioned in the listing and I didn't even notice until I got the lens and looked it over. The lens body is super clean however the aperture was oily and there was some very light haze in the rear element. I'm guessing that this lens was stored away and not used much in it's life.
Physically it looks as brand new as a 60 year old lens can. Originally Posted By leemik 4/22/2014 - CLA'ed (overhauled) by Youxin Ye. He disassembled the aperture and cleaned each blade and then cleaned each lens element.
The lens is now as good as it was when it was new. Eventually all the old Canon LTM lenses will suffer this fate because the grease will break down after 50+ years. If your aperture is oily, it's better to get it CLA'ed before the grease fouls the rear element (which is common in this lens). If you want to DIY, here's a tutorial on how to open and clean the Canon 50/1.2 LTM Internals dust: a few specks haze: none fungus: none separation: none scratches: none aperture: clean Body focus feel:normal aperture feel: normal with clicks scratches and dings: none tarnish/wear: some very slight wear upon close inspection other: non-destructively disabled infinity lock.

A completely non-destructive and reversable mod that improves the experience of using this lens. Look and Feel The lens looks great and feels well balanced on my mirrorless cameras.
I've read some reviews where someone said it was big and clumsy. Well, I guess they've never touched an SLR lens in their life? LOL I think it size is fine.it's just the infinity lock I have a problem with and I defeated that. The focus ring is about a 180 degree turn from MFD to infinity with just the right amount of feel and the aperture ring turns smoothly with slight clicks at every f-stop. Optical Performance This lens gets a lot of bad press but I think it's is a good performer. https://trueefil510.weebly.com/tomb-raider-slot-machine.html.

Wide open there is a sort of glow to the image like all super fast lenses but stopped down to f2-2.8 the glow goes away. This lens is fairly sharp wide open and even sharper stopped down. The sharpness wide open surprised me as others have reported it to be somewhat soft and dreamy wide open. Perhaps I got a really good copy? Bier haus slot free play. Colors are punchy and excellent as all Canon lenses ever made it seems. Especially reds. Contrast is average but all lenses this age don't have the most advanced coatings.
According to the Peter Dechert's (1985) Canon Rangefinder Cameras, 87,875 Canon P's were made. This makes them one of the more common rangefinder models, however there has been a recent renaissance in their popularity with the Leica screw-mount crowd, so their prices has skyrocketed.
I think the lens hood helps improve the contrast a bit.and in this day and age of course all you have to do is boost the contrast in Photoshop. The bokeh is swirly and nervous and can also get 'bubbly' at times. It definitely has a lot of character.
Some people might call it bad bokeh but I love it and try to use the lens at wide open as much as possible. The A7R has a ridiculous max shutter speed of 1/8000 sec so you may just get away with shooting on a somewhat sunny day at f1.2 without any filters. One of the annoying things about this lens is the really long minimum focus distance. Texas tea slot download. The helicoid adapter does help a lot though. Accessories The lens came with the original black metal 'Canon' cap and rear L39 plastic cap.

I'm not sure the front cap is original because I read that the first edition 50/1.2 LTM lenses came with a silver metal Canon cap and the black metal cap was for the later lenses. I managed to find a rare original Canon 50/1.2 lens hood and brown leather case on KEH in excellent condition. They also had an old school Canon 55mm UV filter so what the heck, I bought that too =) Verdict I really like this lens! It has a lot of that vintage charm and produces some pretty good pictures as well. I dislike the infinity lock however and I'm so glad I found an easy way to disable it without doing any damage to the lens. One other thing I don't like is the reaaaally long MFD, even with the helicoid adapter it's still pretty long.
If you can't afford the and want a bit of that charm this lens is a must buy. The Canon LTM lenses are a bargain relative to Leica prices.
