EF 17-40L image. is it sharp enough or not? Please òet me nkow you opinion.

Miti, for my eyes, they do appear to be a bit soft. It is possible since you were high up, that the camera did shake a small amount during the exposure which could cause softness at full resolution.

How much shooting have you done with this lens so far? Have you used a wider variety of apertures that f/8 or f/11? I want to say it looks like you got a soft copy, but I also haven't ruled out all the variables yet. I hope you bought it new and that it's under warranty just in case.

Not much Tyler. It's new and under warranty. I haven't used it at all apertures as yet. Non much shooting opportunities around here as outside it's bad weather... snowing...I'll have some more shots as soon as the weather gets better and ...well. email them to you if you don't mind for a closer look. Before sending it back or even selling it I'd like to be sure it's not me the problem.

Of course Miti. I'd be interested to see some shots at a much higher shutter speed, like 1/400s ISO 100, f/8... That way we could rule out camera shake (even if you're hand holding).

Good news is, it's under warranty. So Canon will take a look at it and replace it free of charge if it is indeed defective or soft. :thumbup:

Thanks Tyler. I appreciate a lot your help. Now one more question, a particular one: I've got a poor sight so I ware specs but how much would influence that thing on taking sharp images? Should an photographer have always a prefect sight for best shootings?

wearing glasses would not effect focusing if you have proper corrective eyewear and see 20/20 through them. The picture looks fine its plenty sharpand has nice detail. The only way to really get it much better would be with some processing tricks or maybe using a tripod to steady the motor. But it looks okay.

If you wear glasses, there's a special diopter adjustment next to the viewfinder. You should adjust this with your eye up to the viewfinder to find when it looks sharpest.

Adjusting the diopter will not effect where the camera focuses, just how the viewfinder focuses the image for your eyes. Look out for something like this: http://www.revellphotography.com/blog/wp-content/uploads/2010/01/Dioptric-Adjustment.jpg

It will help you manually focus much better, but it will not effect autofocus.

Thanks for info on the diopter and the link...Now I'll email you a few more Jpeg file shot with EF 17-40 L that I've found on a folder.

 

[o hey tyler]

Sounds good. I'm going to grab a bite to eat, but I'll respond to you... Don't worry!

 

[Miti]

Okay, I'll do the same. Anyway it takes ages to upload. I don't have broadband here. There will be 7 pics. subjected to you attention.

I have the 17-40 and although I haven't used it much, I've been comparing it to several prime lenses at various apertures at the-digital-picture.com. It really starts to drop off at f/16, but f/8 is suprisingly indistinguishable from other primes like the 24mm, at least on the charts that they have. You definitely want to avoid wide open (f/4), it's really soft there.
