Sigma 28-300mm f/3.5-6.3 DL Aspherical IF Hyperzoom Autofocus Lens for canon slr compatible with Canon t3i dslr


Sigma produces lenses for different brands of camera's. The optics are the same, but the connection differs from brand to brand. So if you have a Sigma lens for Nikon, you won't be able to use it on a Canon or Sony. Unless you buy a adapter. But when you start using an adapter, you will lose the Af in most cases, because the electronic in the lenses differ also. and that can't be bridged.

Can an old film sigma uc zoom 70-210mm lens work on canon digital cameras


In short, no. Not without an expensive adapter which includes a corrective lens (which also reduces the optical quality). Even then, the lens will be fully manual only and might only be operable at the widest aperture setting.

If your Canon uses the APS-C sized sensor (all except a few highly expensive professional full-frame models do) then the 70-210 lens will produce a cropped image as if you were using a 112-336mm lens, so it may also be less useful to you.

It could be condensation inside the lens. It could be a problem with the focusing. It could be other mechanical/optical problems with the Sigma lens. If the problem persists after the lens has thoroughly dried out, take it in to a reputable camera shop and have it checked out by a qualified technician.

My husband has a Nikon F65 NON-digital camera for which he has an APO sigma 170-500mm lens. I am thinking of purchasing a digital camera for him (Nikon D50). Will this sigma lens be compatible? Are lenses...


Yes, the lens will be compatible with the D50.

All lenses are optical: light comes in one end and goes out the other. There's no digital/non-digital about it.

What there is about lenses is the size of the image circle. Lenses cover a certain area. A lens that covers a 35mm film frame, such as the Sigma under discussion, will also cover a smaller area, such as the sensor on a D50. It's possible to design lenses with a smaller image circle. These smaller, lighter lenses are sometimes called "digital," because they are intended to only cover the typically smaller digital sensor. Using such a lens on a full-frame or film camera will produce dark corners. This is NOT an issue in your case.

Rear projection tv picture quality loss


most of these sets have 3 lens for the three picture tubes inside and also a mirror---if it has never had the lens cleaned they could be dusty and this will diminish the brightness and clarity of your picture---if real dirty the picture will look washed out------most of these sets you can remove the back cover(unplug set first) and gain access to the lens ; clean them with a lens cloth or a paper towel with glass cleaner.

Dust inside my sigma lens


Zoom lenses are kind of like a tire pump. They will draw air in (and out) when zoomed. The longer the throw of the zoom, the more air moved. You can try Sigma, they may cover it, but...

A small amount of dust should have no effect on the quality of your images, but I would be concerned about it being transferred to your camera's image sensor over time. ( I assume you are using the lens on a digital body )

70-300DL Macro Super autofocus problem


It is likely that the lens will need parts. Sigma is not the best for repair parts. Typically, the small nylon gears that control the AF break. It is still a useful piece in manual focus. Repair costs would likely exceed its value.

Have you ever heard the expression "Good, Fast, Cheap ...pick any two" ? Well, it's that situation. The kit lens is cheap, and it has a good zoom range (including wide-angle) but it's not very high quality. The best lens for you is probably the 17-55 EF-S -but it is $1000. It is a great lens, and it's efficient and light sensitive, along with image stabilization. Without knowing your budget, I would also recommend the 28-135 EF IS, but it doesn't cover the wide angle range. That one is $400. There's also the 17-85mm, which also has Image Stabization. That one is about $500.
