Depends upon the type of lens. I bought it for my camera but it would not fit some of the new nikon lenses.

Your 55mm lens will require a 58mm filter size and your 300mm lens will require a 77mm filter size, both can be found here on amazon

I believe that this is the unit that used on my 70-200 F4. It is very well made, much better than some of the plastic junks out there.As for fitting the 300, I don't know but I can tell you how to find out. Look up the part number for the canon collar for the 300L, then look up the canon part number for the collar for the70-200 F/4. If it is the same number, then yes, this will fit. If it is not the same number, it is unlikely that it will fit.

Yes! It is a perfect fit and great lens for under $300. Highly recommend especially for kid sports.

Yes, I believe all lenses since the 70s are compatible. The D700 came out after my D300, but I'm sure it works with all the same functionality.

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.

I use mine on a 75-300mm lens. If that lens will fit your camera it should work. I don't know about any other lenses.

Yes it should fit. I use a 75-300 with a lens hood, on my T3i and it fits just fine. plus, there are 3 + 'compartments' in the main opening for more lenses.

Since Tamron SP 70-300m lens has a 62mm filter size which is smaller than Canon 500D's 77mm, I believe you need a 62-77mm step-up ring. See the link http://www.cs.mtu.edu/~shene/DigiCam/User-Guide/filter/thread-rings.htmlI hope this helps.

My 2x2 telephoto lens fit my Nikon 70-300 lens ok, so i dont think you will have any issues but I would double check for sure before buying. Sorry that wasn't very helpful.

I have a 70-300 on one of my d4's and have no problem fitting it with the lens hood on. The other camera is a d4 with a 24-70 lens.

if you have the typical 18-55mm that comes with the camera I dont think you loose quality and will gain significant range of use with the 18-200. I have used this lenses extensively with relevant endurance tests. It is a very resistant. Have not use the 70-300mm

hi,it is compatible with Sony G series 70-200mm, G series 300mm, and 135mm STF lenses

Yes. They are about the same although you lose a stop of aperture with the 70-300. The maximum aperture is f/5.6 instead of f/4. The 70-300 lens is only f/4 near the 70mm end. Otherwise, optically in terms of sharpness, it's about the same.

I have the 70-300 mm and attest that it has good optics and the build quality is excellent. Comparing e two lenses the first observation is they are equal in speed. The 70-300 mm lens will give you further reach than he EF-S lens especially when considering the multiplication factor that comes with EF lenses with a less than full frame sensor camera body. The 70-300 will work out to yield focal lengths of 120- 480 mm and correspondingly it will be of limited use close up where you would prefer a more standard length lens to shoot with but it can be a lense of choice at sporting events or photographing wildlife. Another consideration is your plans for the future. If you are thinking you may some day purchase a full frame sensor camera body then the only option would be the 70-300mm lens. Finally something to consider would be to Google reviews of each lens. There are some very detailed and exacting reviews available for camera bodies and lenses on-line. Hope these initial observations will be of assistance.

If your Sigma 70-300 has a Nikon Mount the Fotodiox lens mount adapter will work fine - as a manual lens.
