A support rig for this lens, must be 23" long?

Definitely, because the optics are great, good for the money, you need to support the lens. I use a canon monopod 500. $38 on Amazon or you can get a third party for less than $20.

Yes. The small camera/lens mount cannot support the weight of a heavy lens.

if you need to fit 23 mm, instead of 13mm; I suggest you call the company for compatability...

There is a 1/4 - 20 thread for a tripod on the bottom of the case. You might be able to use that

It is 23.5in long, but I don't understand which way you are going to use it. It is use for place two cameras , flash on it. There is possible to place 5 things.You can also to buy extra holder for this Multi-mount.I love it. I use it very often.Good luck.

probably not the 70-300 lens. an option is to set the pod support so the lens is partially with something- a limb a rock

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: http://www.amazon.com/Tamrac-M-A-S-Medium-Lens-Black/dp/B00009UTQL/ref=pd_bxgy_p_text_y 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.

I don't have a zoom lens that's this long, but I assume you could if it's an e-mount.

You need to look at the threads in the front of your lens. There will be a notation of the size required there

In exact dimensions? I'd have to go measure. I can put a 5dmkii with 24-105 in, with lens hood. A telephoto probably wouldn't fit.

78mm. Anything larger will need the extra bracket to put in front of the lens!

depending on how big the lens is, but probably not. there is no space specifically for an extra lens

If that lens is less than 70 mm (2.75 in) it will fit horizontally, and less than 200 mm (7.88 in) it will fit vertically.

The longer the clamp the better the stability of the lens on the Tripod or Device. The only exception being when space is limited then the clamp need to be at least the length of the lens ring base/foot

l have used it with a Canon 7D and a Tamron 70-300 mm lens. At least 2lbs in total. A counter weight helps stability.

20 pounds would likely be a bit too much for this mount. Ideally this is better suited for cameras or smaller telescopes.
