Is my 24-105 L wonky or is it just me?
« on: October 20, 2012, 08:10:50 PM »
Having just posted some questions regarding my T3i in the BODY forum I want to post my worries about my new lens purchase here. I snagged this 24-105 L online and it seems to not be pulling in the quality as a previous version I had and show reflection issues I've not seen in my other lens including the previously owned 24-105.

I know this lens was pretty sharp the first one I owned. This one seems to be having issues keep things sharp. Here are two examples:

1) http://www.flickr.com/photos/64364083@N03/8106703478/# (taken at f/5, 1/80 sec., ISO 200, 93mm)
2) http://www.flickr.com/photos/64364083@N03/8106698744/# (taken at f/4, 1/1600 sec, ISO 1600, 80mm)

Finally, I started noticing little green spots are strong reflection issues. I used a previous version of this lens to shot concerts and the stage lights didn't cause problems with that one.

Here are some examples:

3) http://www.flickr.com/photos/64364083@N03/8106670297/# (Green spots are under the carvings MUG)

There is a UV filter on it that came with the purchase. It isn't a top notch one. Could that have anything to do with it or is this all normal?

Cheap/poor quality UV filters increase flare - I suspect that's what is happening here.
EOS 1D X, EOS M, and lots of lenses

Sorry, folks.
Just realized I posted in the wrong forum. Can I get this topic moved?

Yeah, I thought that too but seemed to remain when I removed the filter though, I admit, more tests need to be done with it off.

Did a few more tests inside a local museum today:

This one is without the filter: http://www.flickr.com/photos/64364083@N03/8110300826/#

This one is: http://www.flickr.com/photos/64364083@N03/8110287213/#

Not seeing much dif it seems in those two images at least.

As for the glare, reflections...

Unsure why my post on the T3i issues was removed. These were similarly titled posts with two different issues: one with a camera and one with a lens. Now I am sure to not get any help on that end.
