Adding zoom lens to F55?

You just need any Minolta AF mount lens. Sony Alpha lenses also physically fit as Sony inherited the Minolta lens mount when they bought the company, but as they are a later development not all will be electronically compatible.

The size of the lens depends upon the focal length of the lens and you choose that according to how wide a field of view you desire. Typical lenses are 28 and 35mm wide angles, 50mm "standard" (approximately the same perspective of how the human eyeball sees images), 70 to 90mm short telephoto lenses (a narrower perspective and very good for portraits) and higher numbers are narrower perspective telephoto lenses for viewing increasingly distant objects. In practice, the available lenses will be incorporated into zoom lenses which incorporate a seamless range of focal lengths within one single model. The word "zoom" reflects the fact that you can seamlessly change from say 28mm wide angle through to 80mm short telephoto and every single setting between them

Any zoom which starts at less than 50mm and finishes in the short telephoto range is called a standard zoom and is the lens that most autofocus cameras were supplied with. The next most common size will be something like a 70-200mm which is a telephoto zoom (or tele zoom) and takes you from a portrait lens to a genuine 5x magnification telephoto. You may also find so-called "super zooms" which do the whole job on one, for example 28-200mm. but the more jobs a single lens tries to do, the bigger and bulkier it becomes and the image quality deteriorates due to poorer contrast and greater image distortion at each end of the zoom range.

This is not an exhaustive answer, as there are entire books on the subject, but hopefully it's been of help to you.

They offer chat and free estimates, that is the best thing to do for a lens like that.

M (Manual).

You won't get autofocus, nor will you get any metering. It's completely manual.

HI I need to no what fit the lens is

Most add on lenses are designed to be used at a certain focal length, a zoom should be used (is most effective) when you are completely zoomed out, (really why would you add a zoom lens then not zoom all the way) a wide angle lens should be used with the zoom all the way in (cause your getting the widest angles). As far as quality, you really shouldn't have an issue except you may get black edges depending on how big the end of your lens is. Good luck

Canon currently makes super Telephoto lenses from 300mm to 800mm and a number of zoom Telephoto lenses from 28-300 to 100-400. You can also special order a 1200mm lens from Canon at a cost of $99k! (There are only about 20 such lenses made so far.)

You can also get a 1.4 or 2x teleconverter to further increase the power of a telephoto lens. However, the cameras are unable to auto-focus when the minimum f-stop exceeds f/8, which can happen when you use one (or both) of the teleconverters on these longer lenses, so you have to manually focus the lens.

You can also get telephoto lenses from other manufacturers such as Tamron and Sigma that are built to work with Canon cameras. However, the Canon lenses are generally regarded as the best quality.

Hey needacamera,
The range of an optical zoom lens refers to how wide angle to telephoto the lens covers. An example of a 6x optical zoom would be an 18mm-108mm lens, which covers wide angle to telephoto. An example of a 3x zoom lens would be an 18mm-54mm lens, which would provide a capability of capturing images from wide angle to normal views. To calculate the x factor of an optical zoom you would divide the largest number by the smallest number on your zoom. I hope this helps!

Sincerely,
Allan
Go Ahead. Use Us.

Try zooming in. That usually gets rid of the "vignetting" you are experinecing.

It will not work because it is the wrong thread size. Here is info on the Olympus TCON-17 lens for the 5050: TCON-17 (1.7X) Telephoto Conversion Lens Extend the capabilities of your digital camera with the TCON-17 Telephoto Converter lens. This telephoto lens will increase the magnification of your subject by 1.7x when your camera lens is set to the telephoto position. This will help you bring in the subject when you can't get closer, for example, shooting sports or concerts. Please see below for additional items required to attach this lens to your camera. The following models require the CLA-1 and 43-55mm Step-Up Ring: C-2000/2020/2040/3000/3020/3030/3040/4000/4040/5050 Zoom ....... The video lens is too small (diameter). If you found one with a 43mm thread and put it on the 5050, you would experience severe vignetting (clipping of the corners of the photo).
