What is the inside diameter of the Collar when closed? Thanks! (trying to see if it will fit a Pentax F* 300mm 4.5)

Approx. 65 mm. I say approximately because it's hard to be accurate with finding the center point.

In the open move position 2 9/16th inches, in the closed tight position 2 1/2" give or take a fraction maybe 1/128th"

I don't think this'll be long enough for your lens, though I don't have a 70-200 f/4 to check. I have a 28-300mm which is listed as 4.5" long and only has a little room to spare (height-wise). The 70-200mm is listed as 7" long, and I don't see how another 2.5" would fit.An alternative may be: Tamrac M.A.S. Medium Lens Case (Black)I bought the Large for my lens (which is a perfect fit, without any attachments), and the Extra Large may be a good option for you.

There is not a lens cap that fits the larger open end of this hood that I know of. We have to slide the cap inside to take it on and off. You can twist the hood off and on without interfering with the lens cap when putting the camera back into a bag for example.

Using a caliper, I get 67 mm for the diameter of the lens barrel onto which the collar is clamped. The collar opens up completely but I think you could only go up to a lens barrel of about 69 mm, as larger would not fit well. Nor would smaller than about 66 mm lens barrel, as that is where it is fully clamped. Lots of luck! You know, Amazon is great about taking things back if they don't fit.

Fits my K30 which yes is smaller but I don't think by a HUGE amount, will say lens space is pretty much set to 3 lenses, 200mm will fit unattached.

I'm also a pentax owner. my k-30 with a 35mm prime lens fit fine, with room.

The lens retracts fully into the body of the camera, then there is a built in lens cover that closes like tiny hangar doors. Keep it in a little neoprene case and it'll be just fine.

I don't know but measured the case and its right at 7" deep closed. fits my 3200 with 55-200 lens perfect.

Fits my Nikon D300 with 18 200 lens without the extension. The extension adds four more inches of lens. Love it!

I doubt if it will fit properly. It's designed for 30mm. I'm sure it will lock down though.

I carry a Nikon D3300 in the case with a 18-55mm lens mounted on the body. There are Velcro dividers that come with the case to section off compartments in the case. I have created two other compartments one of which holds my 70-300mm lens with the shade attached in the storage position. If I took the shade off of the 70-300 lens I could probably store a second lens in the second compartment. The interior dimensions are 6 1/4" H, 11" L, 5" W. The walls of the case are well padded as are the Velcro dividers giving your components good protection during handling. The protective dividers are about 3/8" thick.

Not sure what the inner diameter is. However, it does fit the L Series 100mm f/2.8 Macro, but it does not fit the Non-L 100mm f/2.8 Macro.

I have no clue, as this is intended for telescopes. If it works for you, I took the measurement with a caliper on the inside thread and it is 49.5 mm (1.95 inch). Hope it works. Remember you also need the respective T-Ring for your camera.

I'm using it with a 30mm (http://www.amazon.com/gp/product/B001C5WMPI/ref=oh_details_o00_s01_i00?ie=UTF8&ps;c=1) and fits without a problem.

We have a Pentax KR. It fits with lens attached. If you are bringing an extra lens, Im not sure if it will fit. There is not much extra room. Hope this helps.

Might be a bit snug. I have a 18-200 on my D3000 and don't know the dimensions of the 18-300. However I keep a skylight filter and lens cap on the barrel, which adds just a bit of length but still fits without being cramped. Boils down to what you find as acceptable tolerances. Hope that helps.

i just tried my IS 70-200 f/4 collar on the 100L macro lens and it does NOT fit.....not even close....the 100 macro is too large
