The lens you are using might not support the autozoom. Some Sigma, Tamron and other 3th party lenses are known for these problems. Best solution is to buy genuine Canon lenses, the best partners for your Canon body. (No I'm not related to Canon, I've just seen a lot of these problems with other lenses)

I couldn't seem to blur my portrait backgrounds with the canon powershot a1200. can you help me with step by step instructions? does the a1200 have an AV mode at all? thanks


You're trying for what's called a narrow depth-of-field (DoF).

DoF is controlled by three factors: the aperture of the lens, distance to the subject, and the focal length of the lens. This has nothing to do with any particular design, it's simply physics.

The wider the aperture (smaller the f/number), the narrower the DoF. The A1200 does not have an Av mode which would let you control the aperture directly. However, it does have a Portrait mode, which is supposed to give you a wider aperture.

The closer you are to the subject, the narrower the DoF. This suggests that you get as close to the subject as practicable. However, in general you don't want to get too close for portraits as this tends to exaggerate certain facial features, like making noses look bigger.

The longer the focal length of the lens, the narrower the DoF. This suggests that you back away and zoom in. Yes, this conflicts with the previous paragraph.

Unfortunately, it's the actual focal length of the lens that matters here, not the "35mm equivalent" often quoted in the spces. The lens on the A1200 zooms from 5mm to 20mm. Landscape photographers like to use 24mm lenses on their 35mm cameras because that gives them practically infinite depth-of-field, from the flower in the foreground to the mountains in the background. The lens on your camera is shorter than that, so you're going to have a hard time blurring portrait backgrounds.

The best I can recommend is to put the camera into Portrait mode, put as much distance as possible between the subject and the background, get as close to the subject as possible, and zoom in to the longest focal length you have (remembering that the last two are in conflict).

What is the focal length multiplier for the Tamron 18-270 mm Di-II PZD VC lens on a Canon XSi digital camera?


It's not the lens but the camera that determines the focal length multiplier. On some cameras the 18-270mm lens is an 18-270mm. The XSi's imaging sensor applies a 1.6x multiplier on any lens used with the camera, so the 18-270mm will be approximately 29-430mm.

What does 35-88mm mean in feet? This is a telephoto lens on a Nikon F50 SLR. Thank you. Amadeus


35mm is about 0.115 feet (a bit under an inch and a half). 88mm is about .289 feet (a bit under three and a half inches). They refer to the minimum and maximum focal lengths of the zoom lens. They have nothing to do with the distance from the camera to the subject.

The focal length of a lens is a measure of an optical quantity. It may or may not have anything to do with the physical length of the lens.

I want to take a picture that is focused on the subject, while everything else in the picture is blurry


What you want is a limited depth of field. There are three factors that control the depth of field: subject distance, lens focal length, and lens aperture. The greater the distance, the wider the DoF. The shorter the lens, the greater the DoF. The smaller the aperture, the greater the DoF.

One problem with compact cameras is that they have very small sensors. This means that they have short lenses. And short lenses mean they have wide depth of field. This is often an advantage, in that more of the scene is in focus. Unfortunately, this works against you when you don't want a wide DoF.

At the short end, the S2's lens focal length is 6mm. This will put just about everything in focus. Even at the other end, the focal length is 72mm. With a 35mm film camera, most portrait photographers use lenses at least 85mm in focal length in an attempt to minimize DoF to draw attention to the face and blur the background.

Unfortunately, the best you'll be able to do is to set the camera to the portrait mode, get as close to the subject as possible, and zoom in as much as possible. I realize the last two conflict with each other, you'll just have to find the proper balance for whatever you're photographing.

Canon 5D and canon 40D are they type A or type B cameras as per 380 EX manual


Hi Bruce,
You have the latest cameras and they will work with ETTL II with Canon 430EX/550EX/580EX and 580EX II. Earlier models use ETTL and films use TTL.
Hope they are helpful.

My scope will not focus it seems like the focal length was somehow knocked out


Yes it will focus. Put the eyepiece with the largest number written on it into the telescope. DO NOT use the 2x barlow. Go outside during the daytime and practice focusing on a distant object.

PS- focal length refers to the distance between the front lens of the telescope and the eyepiece. Are you saying the focuser itself BROKE? If it is missing the scope is not worth fixing, as a new focuser will cost you about as much as what you paid for the scope.

Image Properties shown....


1: bias means voltage a neg or plus I assume the plus means more exposure.
2: focal length in feet ..if not using auto-focus
3: 4.6 feet
4: digital zoom is something I would never mess with but 3072/3072 sounds like a 3 megapixal square.
5: yes set the exposure to a fast shutter or bias in your case like - 3
6: why sure and quite a few pics in 1 minute with the right camera.

Exposure problem


Your 40D requires that you use an ETTL-II type flash like the Canon 380-EX. What flash are you using?

Trouble focusing with sigma 70-300 DL macro super lens


It will not focus on anything closer than 5 feet.

(From Sigma lens literature)
Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It's the ideal high performance lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range. It also has a switch for changeover to macro photography at focal lengths between 200mm and 300mm with a maximum close-up magnification from 1:2.9 to 1:2. The minimum focusing distance is 1.5m / 59 in. at all zoom settings.

Sharpness problem


That should be a very sharp lens, only thing I can think of is that you have a bad copy. It can be sent into Canon where they will fix it.

First, I would try giving it a full cleaning, and taking shots in good light on a tripod at 17-80mm, just to make sure its really the lens
