Related Questions and Answers

Q: 1. The Canon EF 11-24mm F/4.0 lens I just purchased from BandH has a small thin pile of dust about the size of a piece of corn on the external surface of the front glass near the tip. Is this normal for a brand new lens right out of the retail box upon receiving it? The dust was easy enough to wipe off with Zeiss lens tissues and the glass does not show any sign of scratch by naked eyes. No dust on the internal side of the glass as far as my eyes can tell. Any advice and input will help my expectation of a brand new professional lens.

A: While the Canon EF 11-24mm f/4L USM Lens is a professional lens, as it is also mass-produced in a factory, every-so-often there may be a minute chance of dust or other slight imperfection(s) that may be on the lens. If the dust or item was simply able to wipe off, there may be no other issue with the lens, and as long as the lens performs correctly as designed and you see no other imperfections or issues when testing the lens, the lens should be okay for usage. However, do note we do have a 30-Day Return Policy on the purchase of the Canon EF 11-24mm f/4L USM Lens (subject to the terms/conditions listed on the Return Policy link on the bottom of our website), so if you are not happy with the lens for whatever reason, you may return the lens for an exchange or refund by contacting our Customer Service Department.

Q: 4. Is the Lee Polyester Filter that comes up under accessories capable of being cut to fit the rear holder?

A: They will probable fit. I used Kodak Wratten, but the Lees seem to be similar by reading the spec. You need to cut small bevels on two adjacent corners to get them to feed all the way in. I can stack two filters in mine. Be careful that the lens element does not touch the filters when zoomed to 11mm. Mine do not, but some lenses do.

Q: 5. On a Canon Mark 5 III would this possible be the best lens for trying to photograph the northern lights?

A: I currently own a dozen+ L lenses of all shapes and lengths, when I was considering the purchase I was going back and forth because of the price and I had other glass that was in the range at both ends. Canon was going to lend it to me to try through CPS but my impatience took over. After it arrived it in short order became one of the three lenses in my grab and go bag! Amazing is my answer... such a wide photo with such a low level of distortion on the edges... and the clarity is stunning =M

Q: 6. what about parallax convergence in more close up shots? if that is what you call it.
