My XT & 70-200mm Mount Just Fine!
584807
Just picked mine up from Wal-Mart yesterday and got nervous reading about undersized mounting screw.
For my Canon gear, mine screws on just fine, no problems.  I measured the thread on the monopod; it measured .242 inches for the outside diameter. This is just about perfect, about in the middle of the allowable range for a 1/4" external thread, according to the machinist's handbook.  You can't beat the price of about $15, or the apparent quality with aluminum sections.  This is sturdy enough to double as a Billy Club, if need be! Recommended highly.

Nicely done again Sigma! It's compact and light which is good because when attached to my pretty heavy 70-200mm f/2.8...it.could have led to shoulder surgery! But it won't. Good range...quality build. Very happy.

When I got this adapter, I thought I was going to have to return it, because I could NOT get any of my Canon EF OR EF-S lenses to mount to it.. They would stop at under a quarter turn and NEVER get to "click" status.. after 3 days of this, I found an old "throwaway" plastic mount 50mm 1.8 and "let her rip" (since they both cost the same $$ I figured I had nothing to lose.. It was this or $600.00 for Metabones, so why not..) I did this all OFF CAMERA.. the Panny G7's mount is delicate.. heck, the whole camera is delicate compared to my 7D (brick). after VERY hard twisting I got the lens to "click" in.  It took VERY hard twisting to un-mount also.. but it FINALLY worked!  Got a little easier with every twist.. but it still MUST be done OFF CAMERA because it's VERY STIFF.  Now over that hurdle, the aperture blades are top-notch, and I still haven't noted any blue dots.. I have yet to really examine photos for fine focus detail and sharpness, but a a glance, it seems to be ok; but jury is still out on that.. could be a deal breaker if I cannot get consistently sharp focus..  what IS good about this unit it the aperture BOOST you get, which turns mediacre lenses into fast lenses, and fast lenses into AMAZING lenses.. as long as focus can stay sharp, my 30mm f1.4 Sigma will become UN-GODLY fast!  and still maintain around 37-39mm focal length shooting 4K on the G7!  How's that for a sub- $1200.00 4K end-to-end movie solution!  I now just literally leave the adapter on the back of this this lens as it's so very hard to pull off and put on others.. I thought is could just sit on the Panny G7 body, both protecting the sensor, and providing easy on-off rotation of my deep Canon lens arsenal.. but alas, that's just not meant to be.  I can't have it all.. So far so good tho.. I'll update when I get around to some good sharpness comparisons..
***** UPDATE  *****
I have now field tested this product in the studio and upon looking looking at finished photos, it works charming.. for the price. I tested with my new G7 and the tried and true 70-200 2.8L  Optics were on point.. just can't use the O.I.S. like with Metabones.. but clean image at 16X magnification.. about as clean as the lens native with OIS running..  It comes to life with my sigma 30mm 1.4 though.. VERY nice images that held up under scrutiny.. then I tried a few 4k samples.. again.. VERY nice.. You just CANNOT come anywhere close to this 4k footage and lens speed (aperture)for less than 3X the price of this this package.. which is still less than the going rate for a GH4 body alone..  I just might get a couple more and just leave them on the lenses.. Sliced Bread Indeed..

Picked up an ATN X-sight 2 3-14x at academy. I haven't mounted in on my rifle yet as it hasn't come in, but so far the image quality for this price point is outstanding. I've been messin around with it in the yard for about 2 hours now. Looks like I'll be getting the Thor next!

This fits the Fuji X20 quite nicely. Since the Fuji has a pain in the butt press on cap I like not having to have it on most of the time.

The image quality seems fine.. certainly fine enough for a compact camera. Given it was used by kids as well as me I am happy to have it on. I am very glad I got this little filter for my camera.

One does need to snug it back down once in a while but it is no big deal.

I have a large collection of Canon EOS glass and bought this to use them with my X-T1.  At first, I couldn't get the shutter to fire but then found a tutorial for using lens adapters with the Sony NEX-7 which I also own.  There, I learned to enable a "shoot without lens" setting. It's buried on p. 81 of the X-T1 owner's manual and doesn't say why one would need to use this.  So, once that was turned on, the Fotasy works fine.  Fotasy could have saved me quite a bit of lost time had it included this information in its packaging.  That and some extra effort required to remove it from the lens costs this a star, but overall I'm happy with the product.  The fact you need to focus manually is no problem with this camera, which makes it easy.  The aperture ring is a nice touch.

I am happy with the mount.  It is easy to install to the projector.  I had to do some Jerry rigging to figure out how to connect it to my ceiling, but I think this will be the case because everyone is going to have different needs when it comes to the connection point.  The unit is very easy to ajust and swivels well. Its not beautiful, but not bad looking either.  It works with the BenQ 1080ST, and has a reasonable price.

I was a bit skeptical because the mount was so inexpensive, but for a being a universal mount, it is actually quite nice. It does the job as expected.

So far I have used this with a Sony A7r ii with the 16-35mm lens - not a super heavy combination, but definitely not a "point and shoot" and this holds up very well. I didn't realize there was the next size up, the GorillaPod Focus when I bought this... perhaps that would be more secure, but this is nice and sturdy with my current setup.

Previously I had bought a cheap knockoff that I can't even remember the brand of, and those joints hardly support the weight of a cellphone, even though it looks just like the Joby! That product is absolutely useless since it's always buckling and bending when I don't want it to.

I HIGHLY recommend getting the optional ballhead. The nice part about the ballhead is you can use it on multiple different tripods - it is very nicely made as well and works with all Joby GorillaPods.

WOW! Great value.  I cant see myself using EVERY mount, but just the ones I will use are well worth the 20 bucks.

Great fit on my 600EX-RT's. Have not attached to tripod, but not anticipating any issues. Great balance, and great price!

It works! I was a bit skeptical as well given the price compared to other retail stores -- but I had no issues whatsoever. This was the second mount I put up after a friend assisted me with the first -- piece of cake. Just need the right tools.

Was searching for a small insert that would fit my Fuji kit, because all of the normal inserts are huge and meant for DSLR's, well this one is absolutely perfect for a smaller camera system! I can squeeze my xt2 with a lens on it and my xt10 right along side it, throw it in my backpack and be good to go.  The quality is also very good, not loose stitching, and decent foam dividers. Overall really pleased with this little gem.

Heavy duty and easy enough to install. I used it to mount an older Sony 46" XBR and that thing is heavy! And I like the adjustability (full range of motion, adjustable tilt, adjustable leveling).

The mount came quickly and was very easy to mount by myself.  I was a little concerned with the price of the unit, thinking it might be chincy or break after I put my 52" high def TV on it.  When I first mounted the anchor on the wall I pushed and pulled in order to see if there was any give to it - I didn't notice any movement whatsoever.  As long as it's attached to studs it should be good to go.  Be aware, though, that there are different size bolts.  Of the four total that are needed, the two in the top are the same size, and the two in the bottom are the same size, but different from the two in the top.  I didn't realize that until I installed the two larger bolts on top, predrilled the hold for the bottom smaller bolts, and went to install the smaller bolts.  It didn't turn out to be an issue, as the mount has still been rock solid.  I guess I should have read the instructions!  As others have stated I didn't rely on the level that was provided with the mount.  The HDMI cable seems to be of high quality as well.

It's been installed for a few months now and I have had no issues whatsoever.  I will be definitely be buying more of these when I need to install more TVs in more rooms.

The mount is every bit as good as any I've seen...including those sold in stores for up to $200. One thing though, the internal level is a P.O.S.! Do not trust it! There's a reason they include a second small level in the kit.

I needed a mount that would support my 70" television on a single stud and this worked perfectly. I searched around awhile before I contacted OmniMount and found that this would work for my television (a Vizio E70-C3). It states that it is for TVs up to 63", however customer support informed me that it would work since my television was well under the 80lbs. capacity of this unit. The instructions are well written, mounting was very easy, and I am very happy with this mount.
