p.1 #1 · p.1 #1 · 50L Glare/flare?


Noticing that there is an unusually high amount of glare from blown backgrounds on darker subjects with my 50L. Not sure if this is new or not, but I'm editing a set of photos right now that is really showing this. Apertures are between f/1.8 and f/3.2. Faces have a lot of flare/glare with a ton of contrast reduction and whitening of the subject's face edges that is not coming back. The light source isn't particularly different from previous shoots of a similar type, not really brighter than others like it - but I'm noticing more of that glare.

Is it common with 50L?

Form's back....

Post an example with the exif... If you use the flare/glare the right way, it can add to the image...

And I would say yes... IMHO

I don't see any smudges on the lens that I would normally associate with this issue.

form -- You are the ONLY member here who can't figure out the technical parameters of your gear!

You're getting pretty good photos as a dufus. I can only imagine how extraordinary your work would be if you learned how to use your gear.

Try a contrast ratio somewhat less than 10,000,000:1.

That's a tad harsh.

No need for name calling, IMHO.

To the OP, I've not had much issues with 50L and flare/ glare/ ghosting.
Your post is a good example on how to achieve some flare with the 50L.
In fact, I keep a 50 1.8 to v1 add some well positioned flare, when appropriate.
I don't add flare too often.

Really?

See Def. #3. It says "kindly".

http://www.urbandictionary.com/define.php?term=dufus

Hey, in some cultures, a dufus might aspire to become a photographer. Or not.

AND. . .

It's not as if I'd called anyone a petard, retard, or half-tard.

If form can fun us, we can fun him back. Fair is fair, in Gunzorro Vernacular.

Here are a few useful examples.

"Why do I always explode when someone with a match comes near?"
A: Shut up, you petard.

Why is my camera not a time machine?
A: Shut up, form.

******

Going to lock-down mode with my foil helmet on. Thanks, form.

Form,

The atomic fire shining through the window is probably somewhere around 'Sunny 16.'
At ISO 800 and f/3.2, it is ~8 stops overexposed. Zone 13 or so. Not quite Edgerton territory, but getting there.
Immediately bordering this photonic blast, you have some dude wearing a dark suit. Add a few more stops to the local contrast ratio.

And you wonder why you're getting a bit of flare and scattering?
No commercially viable anti-reflective coatings or lens design will suffice under these conditions.

Curious how many stops did you have to pull this one? At ISO 800 on the 5D3 the black suit shouldn't have that much noise if properly exposed.

Any lens would give you this glare when it's 7-8 stops differences, some are worst than the 50L.

Well done you've found a lens can flare, all looks normal given the bit of glass; it's large front element, the f1.2 lenses do this, even the old FL, FD and nFD glass from three plus decades ago...seems the more things change...huge hydrogen light source, lens pointed near direct at it, darker surroundings in shadowy light ...yep that's flare.

I don't see anything out of the ordinary!

I'm not sure how the 50L would compare with other 50/1.2 AF lenses available in Canon mount, but compared with the EF 50/1.4, it is considerably more resistant to flare. Here is a very old (by internet standards) test, in well controlled circumstances. About halfway down the page you'll see a comparison of flare handling.

In my use of the 50/1.2L, I've found it to do quite well in backlit situations. There is some fringing of window frames, tree branches ,and so forth, similar to what you get with the 85L, and which can be mitigated in raw conversion. Stopping down can almost eliminate it, but of course shooting at or near wide open is an important reason for owning the lens. Veiling flare is low, and when more clarity is desirable, the clarity controls in Lightroom can help.

I don't see a problem with your lens based on the one sample image. It looks more like a scene/lighting/exposure issue, but of course I wasn't there.
