In a full manual lens, it should be easy enough to offer circular "aperture" at all apertures.
-h

what role if any, circular apertures play *wide open* (i.e) at f1.2 in 85mm is debatable.

Circular blades or more numerous blades may have more of an impact in OOF as you stop down...specifically in rendering more pleasing spectral highlights...think of those geometric pentagons one sees with the nifty fifty...

Wide open...say with 85L at f1.2 or 135L at f2... Blade curvature shape may not be a major contributor. 135L has just regular blades.  As one stops down yes it is useful...But both these lenses are used most often wide open.

On the other hand, intentional SA may have a lot to do with why 85L "holds" the bokeh longer at relatively the same level even as you stop down to some extent while the competitors start to show harsher and harsher bokeh...of course as you hit ~ f2.2 or ~f2.8 this advantage is lessened... But One doesn't buy an 85L to use it at f4.0 ;)

The trick is not to let the SA affect the sharpness, or find a balance... and this is where the canon designers did an excellent job with the 85... it is a sharp lens.

...my top used lenses aren't necessarily my top favourite lenses - some are better than others for different needs.

Most used would be 24-105L and 35L....favored children however are 35L and 135L...there is no rule we have to have three and I also can't seem to settle on a third. :)

why is the Canon so much more "bokehlicious" at a given aperture, focal length and distance with similar (?) aperture blades?

Lens design is all about tradeoffs.  For example, the 50/1.2L could have been made sharper - instead, Canon designed with lens with intentionally undercorrected spherical aberration which is part of the reason for the 'creamy' bokeh for which the lens is known.

Yup, both 50L and 85L were same year releases and probably developed in parallel...both share a lot of design and spec strengths and compromises. Some residual SA is an intentional design feature...thats what gives you that dreamy look...and frequently also gives you that directional swirling bokeh in the corners.

As you specify telephoto range and inconspicuosness and possibility of use at night, 135L is a no brainer.

I thought everybody's favorite Canon lens (including all the experts) is the 70-200 f/2.8 ii.

Forgive me for saying this, and it is not directed at you, but I wanted to use the quote from the post:

Yes, 70-200 II is a sharp "all around" lens, but it is also an over-hyped lens where many newbies parrot "this is a great lens" line...

While it is priced somewhat above the common consumer, its ownership doesn't set anyone apart and at least some seem to think it does...almost like a diploma. This lens is quite achievable and owned by many, and used effectively by many...but by no means is it the "be all end all lens" that should herald the arrival of anyone into the photographers' fold... another frequent line..."It does EVERYTHING I need"...  ::)   

I refer to the 70-200 2.8II as the "I too have arrived achievable newbie zoom", not that highly competent pros don't use it...many do and produce stunning images. But the newbies and the "review readers" seek it and own it like it is an end unto itself...almost like a badge...it is like a debutant's cotillion walk down the banister-lined stairs...

So no, 70-200 2.8 II is not one of my top three, and yes I own it.

*gets off soap box*

So, that implies the 85 1.2 shall be another one of the top 3.  Then which lens will take the remaining top spot? 

I am not entirely sure if the 85L as one of the 3 is implied necessarily... could very well be, but doesn't have to be. However, it would be fair to guess that the 135L is one of the three, considering it is frequently ranked among the top three lenses list of many users, including yours truly.

On that note...135L review would be forthcoming soon CR? If only so everyone can fawn over the lens and praise it to heaven? ;)

Sorry as I use low 800 pixel and low dpi export the jpeg compression/reduction may not do the sharpness justice, but it is crisp in the original....crop of the branches attached.

Something tells me 85mm as a focal length is hit or miss almost as much as the focus on the Sigma lens *badump-ching!*

You are gonna get beat up by the sigma crowd with comments like that...I got into boat load of trouble when I was er..lackadaisical about the new Sigma 35mm.

But yes, the 85mm is an odd focal length. I personally find there is nothing that the 85 does that the 135L cannot do, say with portraits...just step back a few with the 135L and you still get magical shots, and the AF is fast to boot. The increased focal length of 135L generates comparable OOF blur. Plus, most people have a 50mm of some kind and that focal length is quite capable of wonderful portraits and detailed still life. So, 85mm sorta "falls" in between.

Isn't that how most people view photos anyway? Best part is: even if it's out of focus it look fine compressed ;)

The photos look great - the bottom one shows a lot off.

Tnx. Yes, nailing focus with this lens is tough even if the subject is inanimate... the center of that flower in the top is in focus...sort of...if you close one eye and look at the leaves during a full moon :P

The problem with this kind of product is always... is it worth the ~2K Canon wants? truthfully, I am really on the fence with that.

Here are a couple of shots from today...that's what reading reviews like this makes one do... play with stuff you rarely use. :) Sorry, I use low dpi and low 800 pixel for export...not sure what it looks like on good size monitors.

In the case of the 1-series, it's not the AF system per se - the 1-series bodies use a higher voltage battery that actually drives the lens' AF motor faster than non-1-series bodies.

Touché. I had a pretty good experience with it on the 5DMKIII too actually, since I worked with the lens over a few different periods, including my time with a 1DX.  I'm still very impressed with MF ninja's who seem to consistently nail their shots with this lens... hats off to you magical ninja's!

Yes, 5D3 focuses a lot faster witht this lens than the 1Ds3... at least to me the 1DX seems to focus even marginally faster than the 5D3 with this lens... but it is still pretty slow. But you don't buy this lens to do action photography and car racing....Canon makes excellent lenses geared toward fast action ...this is really designed for sedate portraiture and still life primarily. Different tools for different tasks.

Did you have any concern with the gap between the protruding barrel and the outer lens body?

Concern? No - it just feels a bit weird when putting it on. But it's such a unique lens in so many ways it doesn't affect how I shot with it.

I think he may be referencing the gap as a dust issue...this lens apparently ends up with more dust inside the barrel with time...it is not weather sealed and the barrel design is frequently cited as a reason that also doesn't help. So it appears to be a concern for some...

I have no strong feelings as there is not any dust in mine...but then again I mostly use it indoors.

There is no need to debate UV filters (again) in this thread. I wish these forums were better moderated.

Yeah...to steer it back...how about that 2-ponder 85L and that odd implementation of FTM that you actually need to read the manual for!  :P

  Colour and contrast are beautiful.   I have all the usual suspects and need a good reason to move to the 50 F/1.2L or the 135 F/2L. 

I think if 50L works for you, and is your preferred standard lens, then 85L is just a little close in focal range and may be a tad redundant for the price. I know many have both and find use...but the focal lengths if one is fair are not really that far apart.

35mm as a standard is a better pairing with 85mm but weather one needs the f1.2 or the f1.8 which does 90% of the L for one-fifth the price depends on the kind of use and of course finances.

Unfortunately, IMHO, the "look" the 85L produces lies in that last 10%.
