More Canon Lens Mentions [CR2]

...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

In other words, you don't know what it means. Good grief. :

What you do not smell is called perspective distortion powder. You can spend a few years building up an immunity to it...or carry the antidote (a TS-E lens).

My 16-35mm doesn't exhibit that much perspective distortion at 16mm, it has some, but trees are still more upright at the edges of the frame than at 10mm on the 10-22mm. I can correct the issues with my 16mm in post (if it's bad enough), and it doesn't cost me too much image area either...correcting TDP's 10mm example would cost a significant amount of image space, and result in a pretty extreme loss of quality.

Oh, and perspective is solely a function of the distance from the camera to the subject. Distance, and distance only. Are you suggesting that to achieve the same framing at 10mm on APS-C vs. 16mm on FF, that you'd be at a different distance? Let's see...10mm x 1.6 = 16mm...seems like equivalent FoV to me. If you're at the same distance with 10mm on APS-C and 16mm on FF, you'll get the same framing...and if you're at the same distance, the perspective distortion will be the same.

It seems your subjective impression is at odds with reality...again.

Pincushion distortion is the image distortion created by jumping while trying to take a photo because somebody shoved a pin in your butt - making you a pincushion.

I like your explanation best.

Just trying to help clear up any confusion.

While we're on the subject, barrel distortion is caused when a gorilla rolls or drops a barrel, which then hits and damages your lens, resulting in distorted images.

Sorry, your pincushion description was spot on but certainly here in the UK barrel distortion is completely lens independent and occurs shortly after the photographer has consumed some of the contents of the barrel! It can have significant effects on focus and sharpness but any concerns about DR are pretty much eliminated at the point barrel distortion occurs . . .

In general conversation people tend to use various terms interchangeably as if they are the same thing. In meaningful discussions I like to make a clear distinction between projection, keystone, perspective and distortion.

I thought the 24-70ii was expensive. Although I bought it. This is just CRAZY. Samyang it is.

I just don't believe it will be $3000. I do understand(and so does Canon) that there is a ton of demand for this lens, but not at this price point...
