Having problems with your Digital Cameras ?

I have read a lot about chromatic abberation and softness at edges of Sigma 70-200 F2.8 lens, what is your experience. The exact lens model is "Sigma 70-200mm F2.8 EX DG Macro HSM II" Galway canon fan.


Answers :

All zoom lenses have softness at the edges and all have certain apertures that are the best for sharpness. You have to experiment to find the ones for your lens. Chromatic abberation is something you would have to use a magnifying glass on your computer screen to see. Don't worry about it.

I'm looking at buying a Canon EOS 400d and wonder if anyont can confirm whether my lens from old Canon EOS 620 film camera body will be compatible.

Hi all, I wonder if you can supply some advice regarding a Sigma17-35mm lens I purchased earlier in the year. Basically if I use the automatic or 'P' setting on my Canon EOS 30D camera the image is over exposed by 1 to 2 stops. If I use the same functions with my Canon 18 -55 kit lens the exposure is correct so I would presume the camera is not causing the problem. The only way I can get a correct exposure with the Sigma lens is to compensate manually for each shot. Please note the exposure p


Try your EOS in AV (aprature value) mode. You should be able to adjust your aperature value in 1/3 or 1/2 steps dependind how you have your Custom Functions set in your camera's menu. Possibly the lens you purchased is for an EOS 35mm. If you use a 3 ... Sigma Digital Cameras

I just purchased (about one month ago)a Canon 50 D with 28-135 is. Yesterday I recieved a Canon 2.8 IS L 70 -200mm. When I mount the camera to the lens ( the 70-200) I notice a little wiggle in the mount attachment. I went back and checked to see if my other canon and Sigma lenses do this on the 50 d and they do. I just seems more noticeable with the larger lens. Is this normal?


The larger lens is longer and the wiggle is the same amount of play but closer to the end of the lens it moves more due to it being longer/larger. Just insure there is no substantial movement at the actual connection or lens and body. It should lock ... Canon EOS 50D Digital Camera with 28-135mm lens

I have a Canon 40D and tried to use my Sigma 28-300 1:3.5-6.3 DL Hyperzoom lens on it but the camera kept telling me that it could not communicate with the lens and that I should clean the lens contacts. I cleaned the contacts several times (which were not dirty) but still got the same results. The lens is 5 or so years old, is it possible that the lens is not compatible with the 40D?


It could be that the lens, being so old, needs a firmware update. Go to http://www.sigmaphoto.com/service-support for a service form and instructions. ... Digital Cameras

I have the tamron 18-200 mm XR Di-II if macro lens. The camera displays the error Err 01 Communication between the camera & lens is faulty. Clean the lens contacts. This error occurs with the tamron lens only. I have used the other lens of canon make & the camera is working fine. this happens only after 55mm range . Please guide for the solution if any.


So, have you cleaned the contacts as you were advised? You do this by removing the lens and cleaning the contacts on the camera body and on the lens where they meet with a cotton swab lightly dampened with rubbing alcohol. ... Digital Cameras

I have a canon EF 70-300 f/4.5-5.6 DO IS USM lens that has a zoom lock switch. When in the unlocked position and I try to zoom the lens it sticks at around the 200mm mark and cannot seem to move it below that positon, I need to wiggle the barrel before the zoom seems to "let go" and the lens goes to other positions. This is quite a problem as the lens cannot be operated in all its positions. Also when trying to get it unstuck, it feels like I am applying too much force and could further damage

I am having trouble photographing birds. Do I use the telephoto lens or the wide angle lens? I also have a macro lens for my Canon EOS 400D SLR Also what settings do I take them at. I have a tripod but the birds are too quick so they have to be for hand held. I am finding that when taking them with the telephoto lens they are not sharp and the background is blurred and not good. Thank you Val


Use the telephoto lens.. wide angle will tend to distort the image and provide too much detail( distraction) around the object of interest. Bird pictures become more interesting when they are mainly of the bird. So when you look through the lens, zoo ... Canon EOS 400D / Rebel XTi Digital Camera

Hi I have a Nikon d200 and with a Sigma 50mm Macro AF 2.8. The lens is a few years old. and it's the first time I tride it on the d200.

I have a Sigma 17-70mm F2.8-4.5 Macro lens working on a Nokon D40X and Nikon D300. For medium to long distances the autofocus does not seem to work with this lens. I think it used to but now I notice that from about 40 feet away the autofocus does not work. The same happens with both cameras. Other lenses work fine so I don't think it is the camera. Is there any history of problems or is it a feature of the lens? thanks, Richard Brand
