It's 30mm f/1.4 but it also says it's a zoom lens. What is meant, in this lens, by zoom?

I don't remember it saying zoom in the description, but in any case, it is not a zoom lens. There may have been a typo. I would disregard any mention of zoom for this lens. It does not zoom to a different focal length; it stays at 30mm.

Are you sure it says that? I've looked over the ad description & I don't see anywhere that it's a zoom lens. The only place I see the word "zoom" was in a customer's question comparing it to their zoom lens. It's definitely not a zoom. It's a single 30mm focal length prime lens that I've enjoyed.

It is no a zoom lens. Might be an error on the listing. It is a 30mm prime lens with largest aperture of 1.4. FANTASTIC LENS

Maybe due to focal length they are classifying it as fixed zoom but I would disregard. Focal length is equivalent to 45mm on FX.

it's 9mm to 10mm manual zoom. Don't know exactly but a guess would be closer to 10X Zoom Optical. No digital zoom.

Yes, this is a fixed lens! So you cannot zoom in and out. But it is a beautiful one!! Best I have made portaits with!!!

The zoom works to the maximum (30x ?). Until you zoom in higher than 3 or 4 x you will get the circle showing from the lens adapter tube but this can be cropped later.

The lens you have is a zoom lens. This is a prime lens. Meaning you can't zoom with this but on the other hand 50mm is good in low light situation. Its Shallow depth of field will make picture look good.

It IS an autofocus lens. I suppose some vendors just don't include that in the description. Hope that answers your question.

This is not a zoom lens, its a short telephoto. For your purposes a 18-200 f/3.5 will do nicely.

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).

It is a T mount lens. You have to have a T mount camera or get the adapter I had to get the adapter for my Nikon d300 T mount is a threaded screw on mount

Correct. Those numbers relate to the lens' focal length, and the longer the lens is the greater the zoom.

Its a prime lens so it has a constant zoom. I used a D90 and it worked perfectly well.

It's both because it is a zoom lens. It's 2.8 capable when used at the 24mm setting and 4.0 when zoomed in using the 85mm aspect.

It will not go to 500MM zoom, you have to use it on manual setting. This lens is more trouble then it is worth.

The lens is a typical folding zoom lens that is at its shortest when zoomed all the way out, and extends two telescoping tubes as you zoom in (higher magnification). I.e., NOT an "internal zoom" -- doing that for something with this zoom range really isn't feasible.

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

The f/# changes as you zoom the lens. At 24mm it is f/2.8, at 85mm it is f/4.0.

It depends on the focal length of your lens and it's speed (I mean open aperture value). Try to set the zoom lens at 90 mm approximately.
