I'm supposing 30" base, 40" base, & 50" base means 30mm, 40mm, 50mm lens..

I ordered the size that was supposed to be for my 40 mm objective lense and it was too small..it fit my 30 mm .22 rimfire rifle..I won't buy another...

Yep. Although the large was very tight and required a LOT of stretching and a little relief cutting to go over the 50mm obj on mine.

Yes - the description is more accurate, talking length and diameter. However - I got a medium for my Leupold 40mm and it was too small/tight for my liking, so I dont know how the large would be. I'm guessing the Small description should be 35mm not 45mm. However, you get what you pay for. I like ScopeCoats if theyre available for a little more money.

I had the 50mm objective lens. So it wouldn't be the same. I went to my local hunting store and they had a chart. Might want to do that. Sorry I couldn't tell ya. But what I have found d out is, if you buy a scope that comes with covers, they are better quality than buyi g covers separately.

Keith: The filter should work since the SX 30 (the one I have), the 40 and 50 all have 67 mm lenses. WRL

I've always considered lenses of less than 35 mm "wide-angle". It's a matter of degree, but I would consider 28mm a wide angle lens. Since around 50mm is "standard" focal length, it is quite a bit wider than that.

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

52mm is for a lens that accepts 52 mm filter and 72 is for a lens that accepts 72 mm filter. check your lens to see the size you need.

I don't have experience with a large lens, but the base is very sturdy so I would expect it to do well.

The focal range of your lenses has nothing to do with filter size. Many Sony lenses are 55 mm in diameter. Each lens should indicate the filter sise on the forward part of the lens barrrel in mm, e.g., 49mm, 52mm, 55mm, etc.

This depends on your lens size. Look at the lens which usually will indicate the size. Each lens is a different circumference. Yours will display this.

Look inside one of your lens caps. It will say "52" or whatever the thread size is.

The 25 and 36 refer to the size of the lens opposite the eyepiece in mm. The larger the lens the more light it gathers. This of course makes for a heavier monocular and a larger one. I have a 10x25 and it is fine. You have to have a steady hand though in using the devise.

I got 49 mm, fits good.....50mm might work...............40mm is way too small!

Check the tube size on your scope, its either 1 inch or 30 mm in diameter, purchase your mount in accordance with that measurement.The number 40 refers to the size of the 'Objective Bell' (front lens) not the tube size.

Read the listing it clearly shows that it is a 58mm search for your lens size and order the correct unit.....

I'm sure it will be fine. I primarily use it with my 50 mm so I can't imagine the 40 not being good. I have also used it with the 18-55 kit and I can still be at somewhat of a workable distance down to about 30mm. Remember with these, the shorter the focal length, the closer you will have to be to the subject. You will have to be very close with the 40mm and all attachments - However, you don't have to use all of them. I do love this piece of equipment and use it often.

The filter thread size on the 16 to 50 lens is 40.5mm. The tech information should have indicated the thread size so you know that a step-up adapter would also be needed.

I think the 55-300mm lens will be pushing it. I have an 18-55 mm lens and it's a perfect fit
