Question: Is lens compatible with Digital EOS Rebel DS6041?
Document: This lens is Canon quality. Works great and I have no complaints. Fits nicely onto my EOS Rebel Xti and takes great pictures!
When people talk about this or anyother EOS lens and the 28-105mm digital being equal to a 44.8-168mm film, You need to understand "THIS IS NOT AN INCREASE IN FOCAL LENGTH" but instead is the crop factor. This Lens 28-105mm WILL NOT MAGNIFY THE IMAGE EQUAL TO A 48.8-168MM FOCAL LENGTH LENS. It instead has a field of view ie:"CROP FACTOR" equal to a 48.8-168mm film lens.
I have a digital rebel XT with a kit lens (18-55mm). This lens is much better than the kit lens, better quality, better zoom, better speed...
I use this lens on the Canon Digital Rebel. It gives me great color &amp; sharpness up to 11x14. Canon makes better lens than this but for this price range you can't beat it. I'd reccommend it to any one. If I lost this one today I'd order another one tomorrow.
I also bought this lens for my Canon Digital Rebel and i think it is a really nice little lens. it is well constructed with a metal lens mount and has a super fast and quiet USM motor. be sure you get this lens and not the cheaper F4 version!the Canon 28-135IS is also a fantastic lens but it costs twice as much and is also larger.
This is a excellent lens for the price. I've brought it on vacation several times since purchasing it in mid-August and I find that this is the lense I've used probably 90% of the time on my Digital Rebel XTI.Pros: Autofocusing is very fast and quiet!! Sharp and solid build.Cons: Autofocus shifts/stutters slightly in extreme low-light situations. No other faults that I've noticed yet.
This lens has replaced my stock 18-55mm lens on the Canon Digital Rebel. The lens is very sharp for the photos I take (close-ups as well as longer distance pictures). One "negative" - the lens is a little heavier than the stock lens which came with the camera. Not a real problem though. One difference - the manual focus ring is to the rear whereas the stock manual focus ring is in the front. The motor is extremely quiet and quick!
This is a great lens. I bought the digital rebel kit recently and soon 'outgrew' the efs 18-55 kit lens. It is particularly soft at large apertures and makes it totally unsuitable for indoor handheld photography. I decided to go for 35 mm lenses rather than 'digital' format lenses as an upgrade to the kit lens. They are lower in price (relatively) and you also only see the center of the lens where the picture quality is the best.
I purchased this lens for my EOS 300D tonight and after a shooting a few test shots my verdict: it's a keeper. We have Abe's Of Maine here in my area and I paid less than the amazon quoted price. Thanks Ed :)
(about 45mm-170mm if it was a 35mm film camera)  If this range suits you, then this lens is an excellent value over a EF-S wide-angle/telephoto zoom. You'll keep all of the features, save money and have a faster lens.The EF series meshes well with the current line of Canon digital SLRs.
Answer: It is an EF lens and will work on any Canon DSLR. Canon makes two kinds of lenses: EF and EFS. The EFS lenses are made for their crop-sensor cameras and fit deeper into the body and will interfere with the mirror in a full-frame body. The easy way to tell is if there is a red dot or a white square, EF and EFS respectively. Red dot will work on any camera. White square will only work with crop-sensor models and will damage the mirrors on other bodies.
