Will this lense work with a Canon 40D?

Yes, with no problems. I have a 40D and a T3i. Works fine on both. Did have a problem with the lens not focusing after about a year and a half, but when I called Tamron, no problem with the lengthy warranty Tamron has with their lenses! Very quick turn around for the repair and it works great again now!

It should be compatible with all Canon mounts. I don't know whether the 40D has IS, so you may want to double-check that before buying. It will still work and might be worth having for future compatibility (I had an IS lens with my 20D for a long time, but wasn't able to use IS until I got my 7D).

Presumably it will. I bought the lens for my Canon 7D. But because of your question, just now I tried it out using my old 30D body. It works; but on a dark, overcast day (as it is here in CT today), the 30D has severe limitations compared to the 7D. With the 30D, I had to shoot at low speeds; but with the 7D, I'm sure I could get acceptable exposures shooting much faster.

It probably works with a D-40, but it works best with any camera that has a lens that has a very large f-stop opening (greater than f3.5, f2.8 or larger.

Sure it will, this lens works with my canon 7D and with my 60D . And does a great job with both of them . This is the best macro lens i ever used and its great for portraits also .

Yes, like all Canon lenses it will attach and operate with the 40D. However, it will not have the continuous focus that has only become available on the T4i, T5i and 70D.

It should. My Canon 40D fits tight but fits so from looking at your camera from pics online it seems that it should fit. Let me know how it goes.

It will work on the 60D with an adapter. Not sure about the 40D or 50D though. If they both have the same connection as the 60D then they will work with the same adapter.

It depends in your lens. As long as it accepts a 58mm filter, it should work. But just remember you have to focus manually. Make sure it accepts 58 mm filter and your lens must have manual focus.

This lens will fit your Nikon D40, but it is based on the filter thread of your existing lens. If you have a Series 7 or 46mm lens thread, this will fit directly. Otherwise, you may need an adapter ring.

This works for my 60D and my 70D. I don't know about the 40D but if it works for the 2 I have, it will probably work for the 40D. Here is the link for Canon compatibility. http://shop.usa.canon.com/shop/en/catalog/remote-switch-rs-60e3 Your camera model is not listed.

I have a 20D and it works perfectly, I believe my 20D and your 40D (yours is a 40D, correct) have the same mount, so it should work

It will work but will not have auto-focus on the d40. The d40 has no internal auto focus motor and relies on lenses with motors for auto focus. This will auto focus on higher end bodies like the d80, d90, and d7000. Keep in mind this lens will also have a crop factor due to being designed to work with full frame cameras.

Yes. I have the D40 and use this all the time. You need AF-S lenses for the D40.

Yes, it will mount and take photographs on a D40. The autofocus will not work though. The lens can of course be focused manually to take photographs, but realize that it is a limitation. Look for any AF-S lens to have working autofocus.

Yes. The 40D accepts type EF lenses; that is what the Tamron 150-600 mm (for Canon) is.

It depends on the filter size that is required for the lens you are using with the D40. For example, Nikon's 18-55mm 1:3.5-5.6 lens will accept a 52mm filter so this lens cap will work with that lens. However, their 24-70mm 1:2.8 lens accepts a 77mm filter so this lens cap will not work with that lens.

I used the kit lens off my D40 and it works fine. It should accept any standard Nikon lens.
