My 300mm lens is 2.25" that is measuring the rim to rim and not the glass on the inside. Does that help at all?

Dear buyer: In order for me to help with this matter I will need to know what's the diameter of your camera lens. This information can be located in the back of your lens protection cap. Remove your cap to check on this number. You can also see this number on the front of your lens. You will recognize it because it has a symbol of a small circle with a line crossing it and the diameter number follows it. Please forward me this number so that I can further assist you,thank you

You need to buy the size that your lens is unless you use converter rings. So to know what it the best size measure your lens and buy that size or one the supports a conversion to your size.

Have you measured the lens? Usually the lens are standard sizes so the 67mm could be a typo and you really have a 68mm.

Well, I'm not sure. It fits my 70-200mm f/2.8 with the lens hood upside down and the tripod mount bracket just perfect. It takes up all of the width inside. There's some length to spare. Soooo... Maybe? Will depend on how big your 300 is. I could send a picture if you like.

The diameter of the lens cap is 3.5 inches or 6.25 cm. There is not a size stamped on the lens cap

Send it back immediately- Amazon is great about returns. Mine is as solid as a brick and is the best built lens I own. You will see when you get another one back.!

I have a Canon 75-300mm lens in the case which is slightly under 6" in length. When it is in the extra pouch I purchased for it, it is 7 1/4" in length X 3 ½" in diameter and fits fine upright in the bag. The top of the bag slips amply over the front of the bag and the two straps are adjustable so I would expect that a lens that is 8" to 8 ½" in length would fit and still be secure in the upright position. A lens that is 9 ½" long could fit length wise in the bag or on top of some shorter lenses beneath or vise versa. The partitions inside the bag allow for several arrangements or can be removed as needed. There are no exterior straps made to hold a really long lens in the 12" to 15" length on the outside.

Sorry I don't lens hood to demonstration fitting this camera case and don't have metric to measure. I think the case logic SLRC-200 is for fit camera

If you convert 30mm to inches it roughly comes out to 1.181in. Leaving about .069in. So it would be close. Maybe a little gap.

Check the lens specifications or check on line for the filter size. It may also be engraved on the lens.

Whether this lens cover fits your lens depends on the diameter of your lens. You can find this on the lens itself. On the *outer most* rim, the lens diameter is the last (minimum two-digit) number in along label. Before or after that number will be an upper case O with a line through it. My largest lens diameter is 67mm, so I use a step-up ring (e.g., "52-67") on every lens. That way, all my lenses accept the same diameter filter. (I purchase a step-up ring, 67mm replacement lens cover, and 67mm protective daylight filter for each lens that has a diameter of less than 67mm. Ultimately less expensive and more convenient than having to buy and carry different filter sizes. Whether this lens cover fits your lens depends on the diameter of your lens.

im not sure how long the 300mm lens is. I use the T3 with the 200mm lense and there is plenty of room

Sorry, but I don't have an expert answer. Here's what I did. I simply measured, with a very accurate ruler the exact outside center cross distance on the lens. No matter if it measures in inches or metric, just Google the number for a conversion. Worked perfect for me on the first and subsequent orders.. The covers fit perfect, are very well made and I'm very happy to have this protection for all of my lenses. Hope this "grass-roots" method works for you. Bob D., Maine

In many cases the camera itself has the filter size printed somewhere around the lens - typically on the lens front rim or outer edge. Sometimes there is also a symbol that looks like a circle with a long line through which indicates the number is the filter diameter. If there isn't one on the camera, you can also check the camera's manual or just measure the diameter of the lens threads with a ruler. Good luck!

Hello Joyce, The "mm" measurement refers to the size lens the filter is meant to fit. Most lenses should have this measurement written on them, and it refers to the diameter of the end of the lens where the filter screws on, not the "35mm equivalent" of the zoom, so it is important that you get the right size for your lens and there is only one correct size. This specification should be listed under the specs for the lens as well, and is specific to that particular lens..other lenses will have different diameters...Hope that helps!

Theres a ring that comes off. Its been a while since ive used mine but you may need to screw on ring to lens first then add the lens adapter. Or try with out the ring? Also it only fitd on my kit lens. Check thread size

The problem is the ring interferes with the lens barrel when it's fully retracted. Zoom it out, attach the ring, then when it retracts it will not quite go in as far but will still work. I hope this helps you out altho I dont know if there is much of a loss in focal length, decide for yourself.
