how long is this lens when at maximum zoom extension?
278851
This is 45-175mm (90-350mm full frame equivalent). So at maximum zoom you get 350mm at f5.6)

It is 4" in length and does not extend with increasing zoom. With the included sunshade it is 5.25" long.

It appears to be the 200 mm. I have not measured exactly per say but it does zoom out that much and it works really well. I keep it on my camera unless I am doing some macro work.

It fits on the lens just fine but is too long to use at only 55mm zoom. It will show up in the shot. It's fine at maybe 75mm on out.

The camera belongs to my husband. The camera is 6.5 inches long with the zoom fully extended.

2.8 will provide a wider view, reference the link for a relative example. http://learnphotographywithtomgrill.blogspot.com/2011/05/lenses-introduction-to-focal-lengths.html

A zoom is lens that allows the focal length (magnification) to be changed continuously over a range. For example, a 25 - 100 mm zoom provides magnifications from 0.5X (wide-angle) to 2X (telephoto). A telephoto lens is one that provides magnification greater than 1X. For example, a 200 mm lens gives 4X magnification. It can be a fixed focal length or a zoom lens. A super-telephoto is one that provides high magnification. Generally super-telephoto focal lengths are in the range of 300mm (6X) to 1200mm (24X).

Sorry I have a Nikon camera and lens and don't know how big big this lens is. So can tell you for sure.

As per Nikon - it is the 35mm equivalent of 22.5-675mm. I have found the zoom when fully extended - I am sorry but don't know the technical of that point - it is best to use a tripod. Even a small tripod works fine. I haven't had ANY trouble with any of the zoom features digital or otherwise for a point and shoot; actually am very impressed. Hope it helps.

You can extent up to as max as you can. 8 or 10'. But its great deal and below link, I used 80% of my shoot with this product. https://www.youtube.com/watch?v=FA1ehEfYRu4

While Doug James answered this correctly, I did look up this lens on Canon Lenses. Normally, this is an f4 to 5.6 lens and is an EFS lens for C size cameras. For extenders the widest f-stop that is acceptable is f 5.6. So when you are at f 4.0 you might be able to use this but it would be very limited. You might want to try Canon extension tubes for magnification. The 25mm seems to do best with this lens. Remember though that infinity focusing is generally lost with extension tubes.

This is a fixed lens at 50 mm. You cannot move the lens back and forth to any other mm.

The strap is 12 cm or a little under 5 inches long. I have it attached to a jump ring that holds my camera strap to the body so I don't need to expend strap to loop it through the body. It just reaches to the end of my 18-55mm lens, but I can fully extend the lens and still get it off. A longer lens would probably require an elastic band to attach to cap to the lens instead of the camera body.

The magnification with my 18 to 55mm zoom lens set at 55mm is 6X. The distance frim the subject is about 4 inches.

Susan, With the zoom extended the camera will focus on anything between 9.8 feet and infinity. However, if you press the selector button to the left (little flower symbol) you can then choose the macro mode. Then the extended zoom will be able to focus on anything between 8.2 feet and 16.4 feet. In this same macro mode, the wide angle (lens not extended at all) will allow you to focus on anything between 2.8 inches and 9.8 feet. If you press the selector to the left (little flower symbol) and then select super macro mode, you can focus from .4 inches to 3.3 inches, but the lens has to be at wide angle--not zoomed at all. Normally, without selecting super macro, the wide angle (not zoomed) will allow you to focus on anything between 17.7 inches (1.4 feet) and infinity. So, for close-ups of flowers: Normal wide angle focus is 17.7 inches to infinity. Wide angle (with macro mode selected) focus is 2.8 inches to 9.8 feet. Wide angle (with super macro mode selected) focus is .4 inches to 3.3 inches. I suggest the wide angle macro or super macro modes because, with the lens fully extended, it will be difficult to avoid blurring the object because of the magnified camera shake/vibrations. I hope this helps.

Yes the lens extends zoom. As stated there is a newer version that extends the range and comes with Tamron's version of Image Stablization

Use the longer mode for most shots. The short focus mode (9 ft or so) seeks like crazy and can be a lot of trouble. The lens operates best at 30ft or so. It is sharp as a tack and fast as hell on focusing. The short range is only good for real closeups. Other than that, leave it in the longer range.

The zoom locks only in the 18mm position. The lens is about 10 inches long when fully extended.
