Advertisement Posted March 19, 2015 Posted March 19, 2015 Hi A miller, Take a look here Anyone have experience with the old Canon 28mm f2.8 LTM lens?. I'm sure you'll find what you were looking for!
Doc Henry Posted March 19, 2015 Share #2 Â Posted March 19, 2015 Adam, May be some infos here first : https://legacycamera.wordpress.com/2012/12/07/the-canon-28mm-f2-8-in-leica-thread-mount/ Why not a Summicron 28 ? Best Henry Link to post Share on other sites More sharing options...
A miller Posted March 19, 2015 Author Share #3 Â Posted March 19, 2015 Thanks, Henry. I'm thinking of it as a classic and compact time machine that is faster than my 28mm summaron, which needs to be stopped down to f8 to avoid vingetting. 1 Link to post Share on other sites More sharing options...
Doc Henry Posted March 19, 2015 Share #4 Â Posted March 19, 2015 .... and here Adam sorry in digital and in french Photos plein taille de Canon 28mm F/2.8 It seems good Best Henry Link to post Share on other sites More sharing options...
A miller Posted March 19, 2015 Author Share #5 Â Posted March 19, 2015 sincere thanks, Henry. I think, however, that the lens may not be the LTM version but rather the EF version. Not sure what EF means, but I have a suspicion that it is not the same as the old LTM screw mount version. 1 Link to post Share on other sites More sharing options...
Doc Henry Posted March 19, 2015 Share #6 Â Posted March 19, 2015 Sorry Adam for the confusion LTM or not Perhaps here : https://www.flickr.com/groups/canon-rf-lenses/pool/tags/Canon28mmf2.8LTM/ In searching for this 28 Canon lens, I am surprised that this lens is called before "Serenar" Best Henry 1 Link to post Share on other sites More sharing options...
A miller Posted March 19, 2015 Author Share #7 Â Posted March 19, 2015 Advertisement (gone after registration) Thank you so very much for helping me out, Henry. I really appreciate it. I came across this collection of photos but I will spend more time looking. From what I can gather, this lens has a characteristic of being low to mid in contrast and soft at the corners when opened up to 5.6 or more, and pretty sharp when stopped down smalled than 5.6. The contrast rendering is of particular interest to me b/c we are now entering a season(s) in which the sun if more directly over our heads which leaves shadows in and around our faces. A high contrast lens has a problem picking up the detail in the shadows. I am thinking that this older low contrast lens may help with this problem and also give me a more classic rendering, particularly with B&W. So we will see... Â Thanks very much again!

Lenshacker Posted March 19, 2015 Share #8 Â Posted March 19, 2015 The 28mm F2.8 version is rare compared with the F3.5 version. Prices seem to be double what I paid for my Nikkor 2.8cm F3.5, which I am very happy with. Â If you Must have a 28mm F2.8, go for it and report back how it is! From the ones sampled on Ebay- one with glass separation, others with coating marks. I would hang-out on RFF or here and look for one. Link to post Share on other sites More sharing options...
A miller Posted March 19, 2015 Author Share #9 Â Posted March 19, 2015 Thanks, Lenshacker - The one I am looking at on ebay is in "near mint" condition cosemetically and optically. It is from Japan. I saw a few others that looked like more of a gamble... 1 Link to post Share on other sites More sharing options...
Doc Henry Posted March 19, 2015 Share #10  Posted March 19, 2015 Adam , you are welcome and It's with great pleasure Some more infos on our Leica french forum here: You know Kobalux ? </title> <meta name="Keywords" content="wide angle, Leica , micro four thirds , Voigtlander " /> <meta name="description" content="$4,000 Leica lens vs a $350 off-brand oldie: Which is better?. We test both, but the answer isn’t as straightforward as https://doingphoto.wordpress.com/2012/04/26/canon-vs-kobalux-28-millimeter-battle/ Best Henry Link to post Share on other sites More sharing options...
A miller Posted March 19, 2015 Author Share #11  Posted March 19, 2015 Thanks again, Henry. No, I've never heard of Kobalux; it is a funny name, though  I have plenty of clinicly perfect optics but sometimes get the urge to go back in time and "see" the world with the same glass that saw it 50 years ago. 3 Link to post Share on other sites More sharing options...
philipus Posted March 19, 2015 Share #12  Posted March 19, 2015 I have plenty of clinicly perfect optics but sometimes get the urge to go back in time and "see" the world with the same glass that saw it 50 years ago.  Hello Adam  Well then you may want to consider also one of the two 2,8cm LTM lenses - the Hektor 2,8cm f6,3 or the Summaron 2,8cm f5,6. I have the Hektor, which is widely recognised as being the worst of the two but still performs well and in a lovely old-school (to use a pop term) way. It is a fine street lens when zone-focused on a camera with Tri-X.  The Summaron is much better if one is to believe Mr Puts.  br Philip Link to post Share on other sites More sharing options...
A miller Posted March 19, 2015 Author Share #13 Â Posted March 19, 2015 Hi Philip - thanks a lot for your post. I know the 28mm summaron inside and out, as I have one that is in really good condition and have used it extensively on my M9, MM and film Ms. It is really lovely a f8 and f11. It vignettes quite a bit at 5.6 to a point where I really only want to use it if there is enough light for f8 or f11. The lens is also quite contrasty. The performance when shooting in direct sunlight is really cool, though; it is pretty glare resistent and when it does show it does so in an interesting fashion. Â The Canon is faster and supposedly is not as contrasty. For $450, I'll give it a whirl:) Link to post Share on other sites More sharing options...

padam Posted March 20, 2015 Share #17 Â Posted March 20, 2015 (edited) I have this lens, not the sharpest towards the edges but I think it renders very nicely, it can definitely produce a subtle 3D effect, it is more of a documentary-type lens. Super tiny, with quite a long focus throw. Not that easy to find a clean one though, haze is common with these old Canon lenses and it can be quite bad if it starts etching the glass or if it affects a cemented element.

Lenshacker Posted March 20, 2015 Share #18 Â Posted March 20, 2015 The later Canon lenses used a (then) new type of glass along with some sort of lubricant that did not get along with each other. If the lubricant got onto the aperture blades, it formed "corrosive haze" on the glass. If you get to it quickly enough, not a problem. If the lens looks good now, chances are someone replaced the lubricant. I suspect Canon figured this out with the last run lenses, and changed the lubricant.

Lenshacker Posted March 20, 2015 Share #19  Posted March 20, 2015 very funny I guess that's why they call you "Lenshacker"? At $450 I'm happy to be the guinea pig on this one...  In the mid 70s, the term "Hacker" was used in the computer department as it referred to someone that made furniture using a sledge hammer.  I started using it after using Pipe Cutters to make RF Cams. Seemed appropriate.    You have to polish it down to 0.01mm. I use fine sand paper and check it a lot.  Brian "LensHacker" Link to post Share on other sites More sharing options...
A miller Posted March 20, 2015 Author Share #20 Â Posted March 20, 2015 Many thanks, steve, Padam and Brian - Steve - I am aware of this, although there is a video out there of Garry from 1982 in Los Angeles using a an early version 28mm Elmarit. Padam - thanks for your insights. Brian - very intersting (and funny) history on you. Made me laugh Link to post Share on other sites More sharing options...
