With some image stabiliser lenses this is normal. Just like when you hold the trigger half pressed, the IS keeps running. If the IS motors are audible, the noise will come from the lens continuously.

The exposure (ISO, Aperture, shutter speed) looks okay. The problem is AWB doesn't match the white balance you chose (or vice versa). Try taking a picture with each available WB mode that's not obviously wacky (aquarium?) to figure out which one most closely matches what the camera chose. You'll have to double check every time the lighting changes. Often ...

Firstly, the 70-200 is not what I'd call a "walk around" lens It can be cumbersome and get heavy after a while especially if you have the f/2.8 version. As someone mentioned before, the f/4 version is a lot lighter. For a regular all-rounder have you considered the following:- EF-S 17-55mm f/2.8 IS USM EF 24-105mm f/4 L IS USM EF 24-70mm f/2.8 L USM ...

I will be controversial here and offer you the EF-S 10-22mm f/3.5-4.5. It's a magical lens. Add a circular polariser to it and you will come back from Europe with some amazing pictures. The EF-S 10-22mm is an ultra-wide angle lens which amazingly focuses very close to about 20-30cm!!! You can take amazing landscape pictures, you will fit the whole of the ...

No sadly it isn't. I had a 40D and sold it when I upgraded it to the 60D. Strange how it still doesn't feel like an upgrade lol :)

There are plenty of choices, but I would suggest two: 1) Canon EF-S 15-85mm Excellent image quality, recommended by many lens reviewing websites as on par with the professional L series lenses. If you want wide angle and good image quality, this is the best choice for an APS-C sensor. 2) Canon EF-S 18-135mm Average image quality, slightly better than the ...

On an APS-C sensor body like 40D, you don't have much options for an all purpose zoom. You also have not mentioned your budget. Here are a list of choices you have: Canon 15-85mm f/3.5-5.6: This is a very good lens with decent wide angle upto portrait length. However, its a little costly considering it's an EF-S variable aperture lens. But image quality is ...

How a camera computes what color temperature and white balance correction to use when set to 'Auto White Balance' is almost as varied as the number of camera models. Although I've never seen an example of such, it would even be theoretically possible for two cameras that are the same model to render different AWB if running different firmware versions and ...

This is only a partial answer, but echoing what xiota said in the comments, what you're doing (learning the camera, playing around with manual modes, manual white balance, trying to understand how the camera makes auto mode selections) is an absolute good thing. Experimentation is great. Now that your first experiments reveal to you that your ability to ...

How about some variation of tethered capture? If you're willing to hook up a laptop, you should be able to control exposure over a series of shots w/o disturbing the camera. You may also be interested in an Android-based DSLR controller that hit the market last year. The 40D is one of the gray-area cameras that's supported, but not with full ...

For sheer reach, you could try the Canon EF-S 18-200mm F/3.5-5.6. The image quality won't be great compared to an expensive lens, and the aperture is a little restricting in low light, but you get a very usable range from wide to telephoto all in one.

For my backpacking trip across Europe, I carried couple of lenses, however the lens that I used the most was Tokina 11-16 f/2.8 that I rented out. It takes a while to get used to it and I'd rent it again if I go back. I did take a longer lens to capture few shots, but nothing captures the streets of Montmartre/Latin quarter.. or the old city in prague like a ...

I do agree with jwenting on the view that you should bring two lens instead of one. On the notion that different lens serve different purposes and the also the extreme odds of one the lens being damaged during the trip. If you are comfortable with Third Party lens, ie Sigma, i can offer you these two suggestions, which I am using for my overseas trip as ...

Am I being unrealistic about image quality expectations from Canon 70-200 F/4 USM IS L Lens? You're being unrealistic that shooting handheld using AF in less than ideal light is going to reveal anything that can be attributed only to the lens rather than any of the other factors that could be affecting image sharpness. Based on the one link that still ...

Don't bother. I agree with Itai's comment. In questions like this it's hard to commit to yes or no since one is so unsure of what is actually broken. It could work after you treat it, but the risk vastly outweighs the benefit. 25% function is still better than 0%, and the only way you can be sure it won't be further broken (or might even get fixed!) is by ...

it produces a continuous noise Even in direct contact with my ear, I could not hear any such noise on my unit. Visit a camera repair store familiar with Canon (preferably CPS) and let them have a look. not sure if it's coming from the body or the lens, though I suspect it's the lense You can activate LiveView without a lens attached if you have no ...

I sprayed electrical contact cleaner into the shutter button while holding the camera upside down. The cleaner dripped right back out of the button. I could see plenty of "stuff", probably flakes of skin, when contact cleaner dribbled out. Bought my 40D used as a backup, and after a couple sprays of electrical cleaner, it works like new. Before I had to ...

If you don't wish to adjust each shot manually then you could get five bracketed shots on a Canon by doing the following: 1. Go to camera menu and enable auto bracketing (AEB) 2. Set AEB exposure to be -1 0 +1 3. Take your first three photographs 4. Go to camera menu and set AEB exposure to be -2 0 +2 5. Take three more photographs. You now have six shots ...

Never travel with only a single lens. One time I did that, it of course failed (aperture blade failure, snapped spring it turned out later). Had not a fellow traveller in the group just happened to have a spare lens and the exact same camera I had (lucky, Minolta wasn't all that common even way back then) I'd have had no photos of 3 weeks of a 4 week ...

Aside from everything already said, and assuming you can put the same lens on both cameras, you have to be sure that the in-camera settings on both bodies are the same; i.e., sharpening, noise reduction, etc. It is likely that this is, in practice, not possible — even when all are set to zero. You need to dig in to the menus on both cameras and set things ...
