Only had a few free minutes to take photos today but below is a video showing some quick casual real life comparison photos with my new Canon 85 and the my Sigma 85. Hope it is helpful for anyone trying to decide!

Suspicion confirmed. The 85 IS’ lens hood is useless in the rain. I mean, they finally weather seal it and then shorten the lens hood so the front element  is impossible to keep dry, *facepalm* and it was just a light drizzle with no wind and I was carrying it lens pointing down, so the rain is just from a couple of shots...

A hood is not principally for keeping rain off the front element.  Do you similarly complain that the very low profile petal-shaped hoods on the UWA zooms are similarly faulty as well? ::)

But is the hood too short?  Or is this just the reality of switching from an externally focusing lens to and internally focusing lens?  See pics (all from TDP): at MFD, the distance from the front element to the edge of the hood is similar.

I'm thinking more and more that Canon is leveraging an internally focusing lens design to give us something no bigger than it needs to be.  Less space to take up in a bag when not on the lens.

Also, though I can't see it in the manual ???, I'm presuming you need to front filter for the weather sealing to work on this one.

Do you front filter when you go into the rain?

Hood lengths are designed to cover potential flare based upon the elements needs am I not correct?

Yes, I use filter for weather sealing.

Well, the primary use for a lens hood is indeed to avoid flare. however, I haven't had any issues with rain on any other lens except the 17-40 (which isn't sealed.)

Even my 35 L II doesn't get rain on the front element like the 85 did today....

That's the norm for hood design, and I'm sure that's true in this case, as well.

Would another ET-83 hood fit?  The ET-83BII (for the 200/2.8L II) is deeper.

Also, though I can't see it in the manual ???, I'm presuming you need to front filter for the weather sealing to work on this one.

Why on earth would you presume that?  The lenses that require a front filter to complete the weather sealing all have in common an inner moving barrel which does not extend in front of the plane of the filter threads.  That includes the front filter-compatible UWA L zooms with internal barrels that move with zooming, and the 50/1.2 with an internal barrel that moves with focusing.  They also have in common a statement to that effect in the manual.

Since the 85/1.4L IS focuses internally and has no such statement in the manual, the logical presumption is that a filter is not required to complete the sealing. 


...except the 17-40 (which isn't sealed.)

Incidentally, the 17-40 is a weathersealed lens (although that requires a front filter as discussed above).

Yes, "based upon the elements" in this application I read as the FOV.  But where the front element is physically located w.r.t to the hood matters, so in this case, internal vs. external focusing considerations matter.  For instance, if the 85 f/1.2L II hood attached to that telescoping inner barrel (see pics from prior post), one would presume it wouldn't need to be so big.

That said, Canon doesn't always deliver a perfect hood from a flare perspective.  Since Canon moved from the reverse zooming + gargantuan hood of the 24-70 f/2.8L I (which optimally shades at both ends of the zoom range) to the standard direction zooming + smaller hood of all the 24-something zooms we see today, we only get optimal shading at the 24mm end.

Thanks for clearing that up, it's been a long time since I had it.

Ah, that would explain why the statement wasn't there.  Thanks, Neuro.

That's a necessary compromise with all 'typical' zoom lenses (i.e., both internally zooming and those where the barrel extends as the focal length increases). 

However, the 85/1.4 is a prime lens, so the hood design can be optimized for that focal length.

That was a great a great video. The rendering from both lenses are so similar it's an easy choice for me.

Canon CPS coverage, image stabilization, smaller size/weight, with first party autofocus and no need to recalibrate. All at the expense of a little additional chromatic aberration?

Yes. I loved the Sigma 85 Art, but after 3 days testing them side-by-side, I sold the Sigma last Friday. I'm in love with this lens and it complements my 135L nicely.
