Almost all lenses have some degree of focus shift, usually not enough to make an impact. It's not a problem with the 85L II.

Interestingly, I found Tiffen makes "combo" polarizer+ND filters in several steps of ND. But they are linear polarizers and only come in 138mm!

Advantages of Crop: ...uses the center (and better) part of lens, thus less vignetting, CA, distortion and overall sharpness.
There's one big advantage of full-frame that a lot of people don't recognize - the variety of zoom lenses starting at 24mm.You can use all of those lens on CROP too. It will change the field of view but it doesn't change the lens quality. Actually, you can even say that "There's one big advantage of CROP that a lot of people don't recognize - the variety of zoom lenses starting at 10mm"

Crop is a value for money. Are there any advantages in viewfinder other than reach? If we are using the same lens (adjust for the reach by cropping), subject will be bigger in view finder of crop. More focusing points on subjects or bigger subject per focus point for tracking might be advantageous right?
On the other hand, if someone prefers wider DOF...will find more advantages in APS-C.
The AA filter is now obsolete.
However what's required in order to deal with it when and where it happens is an image review that is able to display it so that you can look at what you've captured and re-shoot if required rather than needing to wait when you get home and discover it when it is too late.
Or even add moire detection (like there is highlight detection), even if it cannot be eliminated by in-camera processing.
It's insulting and it's personal. And when I say that, I'm not referring to the technical facts. I've been wrong on a couple recently. Fine, I'm willing to admit when I'm wrong. That's a trait I don't think any of you exhibit, though.
...the kind of wicked pincushion you'll get at 11mm.
You keep using that word. I do not think it means what you think it means.
Good grief. I know what it means.
Maybe it's not pincusion distortion... Whatever the hell you want to call it... whatever
The crux of the 'problem' is when people give an opinion that is personal and state that opinion as a spurious fact. Consider the following sets of examples:
- "Canon sells more dSLRs than any other manufacturer."
- "A Canon dSLR best meets my needs."
- "Canon dSLRs are the best."
- "Current Canon sensors have less low ISO DR that their competitors."
- "The IQ of current Canon sensors doesn't meet my needs."
- "Canon sensors have poor IQ."
In each case, statement (1) is simple fact, generally not disputed. Statement (2) is a personal opinion, and completely valid whether or not others share that opinion. Statement (3) is that personal opinion stated as a spurious fact. Statements like #3 are generally untenable, yet people who make statements like that tend to get defensive when their statements are rightfully questioned.
Stating your opinion as opinion is fine...stating your opinion as fact will draw a challenge. Defending that opinion as fact just makes you look foolish. Restating that spurious fact over and over in thread after thread will not only draw a challenge, it will piss people off.
Well done, you described the basics of newbie trolling.
You throw in a few #2's and get interest in what you are saying, then you drop in a #3 to explode the topic.
A thread will really get moving when you have a troll on each side.
People who post #3's are not required to provide back-up or proof to establish a statement. I think that bothers many in this forum as they are well educated and are in a profession that they have to provide proof to back up their work.
In this forum I can say "Lenses made by Nikon are not as good as those made by Canon". It is my choice whether I give hard proof, no proof or even respond at all to whoever questions the comment. Many find it frustrating when someone chooses not to offer proof.
Don, the problem seems to me to be that people give an opinion that is personal or state a spurious "fact", and then get defensive when that opinion is questioned, they take it personally so the cycle begins.
Are the anti-DR guys the only one hurling insults? From my perspective, the insults are originating from both sides, but maybe I'm just crazy.
