Are both the Canon 50 l and 85l lenses weatherproof?

The 50 is with a lens filter on not sure about the 85....

85LII is not weather proof. (Nor rubber ring)

From my experience and as you can see by both of my 85L and 50L examples, at f1.2 the eye lashes, car badges, etc. are all well within 10mm of the center of the sensor where the two lenses are in the comparable zone, which is well within the auto focus points on all Canon cameras. If I want the far edges and corners sharp, I just stop down.

And even if a lens is relatively sharp all the way to the corners at f1.2, in this three dimensional world, you couldn’t get any but a small part of the scene like the closest eye or the badge in focus anyway unless it is very flat like a brick wall or very far away like a landscape. In either case, wouldn’t it be easier to just shoot them at f5.6 or f8 where the lens is much sharper anyway?

I’ve heard the wide open corner/far edge sharpness argument before. I’m curious. In what type of photography (other than focus chart bragging rights) is this important, and could someone please post an example? Thanks.

By the way…

The side by side comparisons of lenses of different focal lengths like the one you linked to are basically flawed because to get the pictures you see here the same size, one of the pictures has to be resized, cropped, or taken from a different distance, thus rendering the comparison moot. If you don’t believe me try it yourself.

I buy fast primes so I can use them wide open not stopped down, otherwise I'd stick with zooms for the convenience. If you feel your 50L is similar to your 85L wide open and you're happy then that's all that matters. While I still consider the 50L a great lens I use it within its limitations - the same limitations of which I do not experience with the 85L wide open.

I use fast primes at wide apertures to isolate and make a certain part of the photo like the closest eye or car badge stand out. If I want it to be sharp from corner to corner like a landscape, I stop down the lens I’ve got on my camera or like you change to a zoom for the convenience.

I don’t “feel my 50L is similar to my 85L,” I know it is, and posted the pictures to prove it and show I don’t have a problem with my 85L. I don’t feel corner sharpness at f1.2 is a “limitation.” Just like I don’t feel I as a human have a “limitation” because my sense of smell is not as good as my dogs. In both cases, due to the type of photography I do and how I greet others, I feel it’s irrelevant.

I accept the fact that the 85L is sharper than the 50L at the corners and far edges at f1.2, and that others may think differently as to whether this is important. I just don’t understand why.

So…Again…And this is not a challenge; I am sincerely just curious. Please help me understand.

Can someone please tell me in what type of photography (other than focus chart bragging rights) is corner to corner sharpness at f1.2 important, and please post an example?

Thanks!!!

I think the performance and behavior of the 50L changes quite a bit with each different body model. I have only one out of 4 which worked semi-okay on my 5DII. It gave me just enough so I could see what it is capable of and that it has potential but otherwise, it was relatively unusable. The rest of the ones I tried were a total junk. So when people say the lens works really well, I'd look at what body they are using with it. Just something to consider ... On the other hand, the 3 85Ls that I owned were all phenomenal. One of them was MACRO sharp at 1.2.

I recall someone mentioned the 5dmk3 worked extremely well with the 50L. It just dawned on me that one reason I have a bad taste in my mouth thinking of the 50L is because when I hired a second shooter for a wedding he confidently used his prized 50L with 5dmk2. 90% of the portraits of the groomsman and bridesmaid were out of focus and unusable. I must mention the 50L was deemed "within spec" when he shipped it to Canon professional service!! What a great lens LOL!!! I blame the lens more than the person behind the camera. However the photos appeared to be somewhat decent but I guess more thorough testing should have been done before such job. Minor pixel peeping showed the crap back focus/focus shift that is sooooooo common in that friggen lens. Thankfully my 35L, 85L, 70-200 f/1.8ISmk2 and 24-70L worked flawlessly.

My 85L is shockingly sharp at f/1.2. Always land the shot for slow/static subjects.

When I do purchase a 5dmk3 I do seriously consider looking into a 50L.

It isn't important in my opinion. As you say, shooting wide open gives you the ability to isolate a subject and corner to corner sharpness is irrelevant as it wouldn't be in focus anyway. I can never get my head around people complaining about soft corners wide open on fast primes. The exception are the fast super teles where they are sharper in the corners, but then again look at the price difference!! Also, it's 'easier' to make telephotos sharp in the corners due to optical physics. Anything less than 100mm is more difficult, but the 85L is pretty good! The 50L less so and don't look at the 24L wide open at the edges or the pixel peepers will have a heart attack! ;)

Okay, here's my quick test since I personally own a 50L and CPS sent me a 85LII to test out for a week.

Basically a run down pro and con from what i've experienced.

50L
PROS: Lighter
Quicker to focus
No focus by wire
Smaller
Sharp at f1.2 is a hit and miss but by f2.0 and up it's tack sharp everywhere.

Cons:
Focus shift (I haven't experienced it)
Focus is a bit iffy from time to time if focusing using any outer point and at a very wide aperture (f1.2-1.8) Usually center point, it's always tack sharp. I'm using a 5D3.


85L
PROS: subject to background seperation and bokeh is beautiful!
Very sharp at f1.2 and then once stopped down, even sharper.

Cons:
Heavy.
Focus by wire
Slow focusing? (TBH, on my 5D3 it focuses fine for me. Then again i'm not shooting sports with this lens.) The 85 1.8 i had def. is faster but that's mostly bc of the less amount of glass.
Price. Around 2200 new and 17-1800 used.

Here's a couple shots i did from f1.2 and f2.0 center point only, all straight out of camera with no sharpening and slight bump in exposure.
50L

My 50L is a hit and miss at f1.2. Sharp but not OMG tack sharp like how it is at f2. My copy is at +5 to +6 according to Reikan Focal and with my tests before I even purchase Focal.

85LII

Now the 85LII i had required +5MA to get sharpest.


Now some real world shots.

I often shoot with my lenses wide open whether it's a creative choice or a technical one (to raise the shutter speed to stop subject movement or to use the lowest ISO setting etc.). Having a lens with soft edges is fine if you're happy to have your point of critical focus more in the centre of frame when shooting wide open. Whereas my point of focus is often way off centre and the 50L softness wide open can be annoying where work needs to stand up to a professional standard to produce large prints or the like.

Wide open my 85L copy produces significantly sharper images than the example image you posted so this may possibly explain why your 85L is similar to your 50 in performance at f/1.2

Nice write-up Bryant. The real world shots tell the tale for me. Both look wonderful in their own way.

The 50 is nice. I have the 85 coming for an event. And if givin the choice I would buy a 200 F1.8 at the drop of a hat over the 85. But I shoot products for a living and Sports for extra income, web features etc.

I think if I did more portrait based images the 85 would be good. But I know I could get by with the 200 if I can find someone to buy my 70-200 for $3K it can hapen!

If I may ask,in what aperture settings doesthe 50 F1.2L produce the sharpest images?
Thanks.

F1.8-F2.2

But using Broncolor strobes at F 8 would be the best bet. :cool:
