Haoge LMR-SM140S Lens Collar Replacement Foot Tripod Mount Ring Stand Base for Sigma 100-400mm F5-6.3 DG DN OS Lens Sony E Mount Art 105mm F1.4 DG HSM Built-in Arca Type Quick Release Plate

Works great, heavy but good value for this price.

This on my Sigma camera lense was perfect as it help on strong but it does sometimes come loose and starts to move but you just have to tighten it again. the stability and mountability is good along with how easy it is to just slide it into your lense and tighten it and remove it after. It definitely is a very versatile item to have for your sigma camera that while using your tripod!

Ok, I have had this collar installed for about 2 months and it is a necessity for a lens this big. This lens fully extended looks like a modern age bazooka. With that being said, I recommend one of these if you are doing photography via tripod. It takes a lot of stress off the eMount body. Now, I wish Sigma would provide these via the maunfacturer with the lens, but this is relatively inexpensive compared to the name brand one. I still honestly think it cost a bit more than it should, but Sigma drove the price up for the 3rd party mfg. Overall, its a nominal price you pay for protection to the camera body, lens, and usability via tripod. I definitely recommend one if you have this 100-400mm lens. Time will tell on durability, but it feels that it was made well.

So far, I have only had good impressions of this accessory. Its movement is smooth and fluid when switching from horizontal to vertical. Keep in mind that it does not have stops, so the plane may be tilted and you have to use the guides printed on the accessory as a guide.

This works very well, turning it is very smooth and catch free. This design is more difficult to put on than Sony's design but that is Sigma's issue, not Haoge's. Also, this is less than half the price of the one Sigma makes for their 100-400mm lens. Highly recommended!

I have the Ulanzi ZERO F38, this did NOT fit into the bracket. As for the collar itself, it seems heavy duty, and sturdy, when mounted on my lens. All metal construction. If it fit my tripod, I'd definitely keep this. Edit: Ulanzi now offers a new plate as a separate purchase. If used on the Ulanzi tripod, you use it in one direction, if on Peak Design gear, you use it in a different direction. It’s ridiculous this has to be paid for as a separate item, it’s like ~20 bucks it should be included for free, or upon purchasing the tripod get a free coupon. So annoyed with this purchase already, and have a bad taste in my mouth for Ulanzi products. Remember, this tripod came out in August - without a ball head - asthe Y model, I think it was called. Then just last month, this F38 model comes out with the ball head. It’s easy to show that Ulanzi engineers aren’t forward thinking, so buyers beware.

For half the price of the lens' original collar, you get basically the same exact product. Follow the instructions when installing it, paying special attention to aligning the marks on the collar and lens. For people wondering, you must remove the rubber ring from the lens first in order to install the collar. Once installed, this is a sturdy product that I feel confident will keep my lens secured. I have used it on multiple shoots on a rapid sling strap and on a tripod. Not once have I worried it wouldn't hold my lens properly. Seriously, get this one and take the extra money you would have spent on the manufacturer's collar and go buy a lens filter or two. More bang for your buck!

I ordered the Sigma 100-400mm DG DN OS lens and added this as an alternative to the very pricey Sigma lens collar at 1/3 the cost. No regrets at all. Well constructed, solid feel, and perfect fit. No instructions were included but easy enough to figure out. Comes with an Allen wrench to switch out the base. Only minor quibble is that the white alignment mark on the collar does not quite have the camera level if you align it with the alignment mark on the lens, but that's not a big deal to me. Highly recommend.

100-400mm F5-6.3 DG DN OS [ソニーE用]にて使用。 精度も質感も良く、純正品に拘らなくても十分満足。 回転もスムーズで装着後はレンズ本体に傷が入る心配はない。

Passt. Wackelt nicht und macht, was es soll und das für wesentlich weniger Geld, als das Originalprodukt. Ich lasse es dauerhaft am Objektiv, weil ich damit einen stabilen Griff habe und nicht in die Versuchung komme, das Gespann an der kleinen Alpha 6500 festzuhalten.

Purchased for a Sigma zoom lens. Works great.

Was looking for an alternative to the Sigma overpriced mount that should come with the Lense but does not! maybe a hinged Lense release or a swivel at the mount would make it perfect but hey detach the Lense to remove & use your tripod that it attaches too is easy enough . 4 out of 5 stars
