what is difference between zoom,telephoto & super telephoto ?

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).

Only the 18-55mm EF-S IS STM Lens + EF 75-300mm f/4-5.6 III Telephoto Zoom Lens are Canon brand. The others (wide angle and 58 mm telephoto) are a brand I wasn't familiar with and actually we haven't used them yet.

You do not use the zoom to focus, you use the focusing ring to focus. Two totally different things. The zoom changes focal length, the focus ring changes focus.By the way, I am a pro photographer since 1965. It will work best with a prime lens. They are sharper than zoom lenses.

F4.5-5.6 DG OS HSM for Sony full size corresponding SIGMA telephoto zoom lens APO 120-400mm Full size corresponding high magnification ultra telephoto zoom lens equipped with a camera shake correction mechanism OS. Super telephoto 500mm up, shooting is possible. Equipped with a (Optical Stabilizer) image stabilization mechanism OS, I show the effect of correcting about four stages. For Sony, Pentax also can be used in-lens stabilization, framing is easy with the viewfinder image stable.

The IS is a huge lifesaver in this telephoto of a lens. When you have a super wide lens with IS, the effect is helpful but skill can equalize it out. At over 100mm focal lengths, IS becomes critical for getting sharp focus.

The Lumix lenses (including this one) that are called "Mega OIS" are manual zoom. The ones that are called "Power OIS", including the very disappointing H-PS14042, are power lenses

This lens is a lot better than kit zoom lens, first: the speed, at 70mm and 200mm or in between the faster speed is f/4. In the kit zoom lens change making it slower at longer focal distance. This lens makes sharper image, beatifull colors. The kit lenses are made from inexpensive materials to keep the price atractive to beginners.

I believe the optical zoom is the only difference. It is 24x vs. 30x optical zoom.

It has two controls for zoom, and you can use either. One is in front of the shutter release, and the other is on the lens. You change to manual focus in the menus. There are no control rings on the lens.

One is 3x-9x power/zoom, the other is 4x-12x power/zoom. There is no advantage as they are both vx-2, however, one of them zooms further than the other.

Both works fine. The only noticeable difference is in the range, I use the zoom a lot so for me it was worth the expense

It is 12 megapixels vs 10.0 for the Canon. It is 4x optical zoom vs 5x optical zoom on the Canon. We had the first version and loved it and bought this one this summer because we wanted an underwater enclosure. We have only had Olympus cameras since 1999 and we love them. We have two of these smaller cameras, a slightly bigger version and a full blown DSLR and we have never had any problems with them and we love the Scenes features in the ZX series cameras. And they are a couple hundred bucks cheaper than the Canon's that I can see. Hope this helps.

The camera has 30x optical zoom. There are 2 zoom control buttons one near the shutter button and the other on the lens mount. When you push the zoom control knob/switch to T (telephoto) the lens moves forward and extends from its mount and once extended when you control the knob to A (wide) it will retract physically back into the mount. The lens barrel cannot be removed to attach another type of lens though. I hope this helps.

Zoom is controlled on the lens. This camera is like a miniature dslr where you can have different lenses attached. The lenses will generally have a focus ring and a zoom ring which depending on what direction you twist them, will zoom/focus in or out.

The LX3 is a completely different kind of camera from those tiny sensor megazoom cameras. On the other hand, the image quality difference between the LX3 and the Canon G10 (with 6x zoom) is very slim. The Panasonic does have a faster lens, which is very useful in low light situations. However, the wide-angle-only zoom range will turn off a lot of people.

The lens that it comes with goes from 14mm to 42mm, so it's a 3x zoom. It's equivalent to a 28mm to 84mm lens in the 35mm format, making it a moderate wide to moderate telephoto lens. Since the lens is removable, you can replace it with just about any other micro four thirds lens and many other lenses with adapters. You'd probably be happier with the e-pm2 though, it's a much improved camera.

This lens is for close up pictures at relatively short distances. The other is a telephoto lens for taking close ups of larger items at longer distances.
