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

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.

If you have this 50mm focal length f/1.8g lens: http://www.amazon.com/gp/product/B004Y1AYAC/ then the correct filter thread is 58mm.

2x means that there are two of them in the package. And yes this will fit your lens.

The L and B refer to lens and base. You can buy just the base and a custom lens or the base and lens together. I bought both the base and the 18-55 lens that comes with it and a separate 10mm ultra wide angle lens. Both work very well.

It depends on what the size of the lens you have. The ones that are in this kit are only 58mm filters. For me the lenses were to big for my 43 & 52mm lenses. But other than the filters the kit is fine. But I would search on amazon for the size of the lens (the size of the lens is on the outer rim of the lens) itself. Ex: 30mm, 32mm, 38mm, 40mm, 43mm, 45mm, 52mm, 58mm ect.. but again the lens in this kit are only 58mm and a upgrade ring to go from 58mm to 60mm

30mm is correct. I confused another Bushnell scope with the one in question.

Probably a 50 mm would work better for the job, but this macro lens works beautiful on both worlds. And it's reasonably economically

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.

Look at the very edge of your lens. There should be a number that will give you the true ring size you'll be using on your lens. If its 50, you'll need a step up ring, available here on amazon or even Best Buy I'd you like. This will fit on a 52mm thread. Just because the lens itself is 50mm it could have a thread size that is from 48-52mm, generally. If you already have a filter, the size of the thread will be listed on the edge of that.

If you are referring to the F2.8 versions of both lenses they are about the same size and weight and such the lower the f stop number it shows the larger the lense typically. (So wider it can open the larger the lense ). Small lenses will be ones that can't open less then 4.0 f stop any mid to high grade lense will be larger than the base lenses in size and weight that being said the lense I bought is notHeavy and is not bad the larger 70-300 f2.8 is very large and heavy enough I mount the tripod to the lense not the camer as to Much strain to the mounts between the camera and lense would cause damage over time.

The diameter of the lens will be printed somewhere on the rim of the lens. The number on my 50mm lens (focal length) is in small print on the 'bottom' side of the lens when it's attached to the camera and has a 'theta' sign in front of the number. My 50 mm (focal length) f1.8 Nikkor lens is actually 52mm in diameter, not a 58mm, so that filter would NOT work on the lens just because it wouldn't fit. You can purchase 52 mm filter sets, though.

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.

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.

My assumption is you have a new lens with a lens cap. If so look on the underside of the lens cap, the size will be marked there.

This is for a lens with a 72mm filter size .. you would need to check the filter size of the 50mm to determine if it will fit.

The objective lenses is 50mm but the OD of the objective end of the scope is 58mm. If you goto Brownell.com and look at there flipups they have a chart that will provide you the information.

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.
