Canon 135mm F3.5 RM

[gmazza]

<p>Found one of these in the Brazilian auction site.<br>

<br />It has a 10 blade preset aperture but they not form a perfect circle when stopped.<br>

<br />The search engines returned few (almost noone) references to this one.<br>

Is this lens a true rarity, a hidden bokeh king, or only a few were produced due to a problem etc....<br>

<br />Thanks</p>

<p>It's an R-series lens made for the Canonflex (1959). See the Canon Museum:</p>

<p>Thanks, this is the lens, but there are no online sample images taken from it or owners reviews, is that that rare ?</p>

<p>What's the serial number of your lens? This will give a clue as to how many Canon made. 135mm was a fairly popular focal length back in the day so Canon probably made a fair amount of these lenses. Today, most sit unused.</p>

<p>Yours is a Sonnar-like optical design also used in later Canon SLR lenses. You'll love the photo quality!<br>

Collectively, I think these R series lenses would have sold in smaller quantities because they were Canon's initial entry

into the single lens reflex market and their SLR customer base was being created from zero. Today, 50+ years later, they

are all somewhat uncommon with the exception of the R 50 1.8 Super Canomatic.

 

My own R 135/3.5 #10234 is a marvel of simplicity and a good performer too! It's quite possible I am its first user as well,

because it arrived without any signs of handling whatsoever and crystal clear glass.

<p>Excellent folks, thank you very much for your considerations.</p>
