Bad Lens ?
Jan 25, 2012 05:36:00 #
I purchased a Sigma 28-300mm1:3.5-6.3 zoom lens from Ebay to use on a Canon EOS Rebel T3. The pictures below were taken 30 sec. apart set on auto landscape. I have not had this problem with any other lens. What do you think ?

The first picture looks pretty good. Fairly sharp. Did you try different settings on your camera? Do a few shoots around the house and see what happens. When you post pictures, check the little box that says (store original) that way we can get a bigger picture to look at.
I shoot Nikon and it took me 2-3 weeks to get the hang of this lens. But never had this happen. You might try to clean the contacts on the camera and lens.
Send us a few more at different settings.

Auto Landscape.
does that mean that the camera is picking the ISO and the other exposure settings?
Something is definitely whacked in the exposure.

Something is definitely whacked in the exposure.

Thank you Erv. I will go out today and play around and see what I come up with.

Yes that is what it means.

Welcome! Start with the auto program first. Do you ever shoot in manual? Might check to see what you have the setting at in the camera. But if it only does it with this lens I am guessing dirty contacts or it might be a bad lens. Post what you come up with picture wise.

I don't shoot in manual but I'm going to try today. Will spend the afternoon with Bryan Peterson's 'Understanding Exposure' and see what happens

Thats a good start. When you take a picture go look at the settings the camera used and write them down. This way you can keep track of what the camera is doing on each shot. Also don't forget to clean the contacts on both.

Make sure the aperture blades are not sticking...That can cause this type of problem also...

Good call!! Wish I would have thought of it. It has happened to me on one of my old film day lenses. Guess I am getting old. ;)

Looks like the aperture is sticking, if you are not in manual turning the aperture.

Looks like it could be sticky blades to me too.
I had an old 80-200 2.8 Nikor with that problem a couple of years ago.

Is this fixable without blowing the budget, or should I return to the seller and buy another one ? I think this could be my 'stay on the camera' lens.Like it better than my 75-300 which is on most of the time.

Are you even sure that that is what the problem is?
