Haoge LMR-OM415 Lens Collar Replacement Foot Tripod Mount Ring for Olympus M.ZUIKO Digital ED 40-150mm F2.8 PRO Lens Built-in Arca Swiss Type Quick Release Plate

Good product. Received the right product. Thumbs up.

So far I am quite happy with this purchase. The product fits well and rotates well. It seems like it will serve its purpose well, and it has seen some use on tripods and equatorial mounts. I *did not* have the problem with the accessory not holding tight once tightened down. Maybe the product has been improved? Of course, the real test will be how this holds up over time. I’m normally hesitate to review on that account, but thought I would in this case as my product does not exhibit a problem many others have mentioned.

I recently purchased a used Olympus 40 - 150 f2.8 Pro lens, which was reduced because both the lens hood and the tripod foot was missing. I noted in the reviews that some people were having problems with getting the lens to be gripped solidly by the clamp. As there are no alternatives to this device, I went and bought one anyway. On arrival my copy had the same problem as others had described and so looked how to improve the lock. I first tried a thin elastic band around the lens inside the engagement pins, this worked, but I was concerned about longevity. On closer inspection I realised that the circlip that prevents the locking screw was preventing the clamp from closing to it's utmost. I dismounted the lens, removed the circlip and reassembled everything. Now the clamp closes fully and grips the lens securely. I next disassembled everything again and placed the circlip on a flat part of a sharpening stone, then ground off the paint and a small amount of metal using my finger to grind the circlip in circles. After reassembly the grip was stronger, but still not achieving full lock. I had a couple of more goes and eventually settled on a grip that needed a large amount of force to make the lens rotate. If you must have a full grip just remove the circlip, but look after the clamping screw and circlip, if you remove it. However, how often is that likely to happen and why would you anyway?

レンズとの取り付けにガタがあり力を加えると回転してしまうというレビューがありますが、私の購入したものは対策が取られたのかしっかりと取り付けられ、ガタもありません。また、商品説明にはありませんが、以前のレビューで指摘されていたとおりQDソケットが付いています。

I bought this foot specifically for the Arca-Swiss grooves and for the possibility that the foot/plate could be removed and reversed. Haoge implied that it could and I'm happy to report that it is easy to do and remounts solidly in the reverse direction. Having it in "reverse" enables me to mount the lens+TC+camera body in balance on my Wimberley Mono Gimbal. It brings the CG of the lens right over the foot, which you can't do with the original Olympus tripod foot. Just try sitting the lens+body combo on the Olympus tripod foot on a flat surface. It'll tip backward. With this easy mod, the rig will sit level, which means the CG is over the foot. You need only a 3 mm Allen wrench. Easy peasy. Update: Some reviewers complained that the collar does not clamp tightly enough to keep the lens from rotating. I found that to be true. The clamping screw comes to a stop, but the lens can still rotate. But, I found out why and solved the problem. See the first photo and read the following: I was using the collar with my 40-150 Pro today and found to my dismay that when I tightened the knob on the collar, it wouldn't stay in position. It could still revolve. Some reviewers had mentioned this on Amazon, but I hadn't noticed it. I took the collar off and examined it closely. In the gap in the collar where the thumbscrew clamps I could see that there was a washer that kept the clamp from closing all the way. I unscrewed the thumbscrew as much as I could to expand the gap, and could see that there was a C-clip on the screw that got in the way. I was able to slip a small screwdriver into the gap and pop the C-clip off (careful, it'll fly, so watch out where it goes). After I removed the C-clip, the clamp will now close all the way and the collar clamps down tightly on the lens. But, without the C-clip, the thumbscrew could fall out if loosened all the way, so you'll have to keep an eye on it. Another update: my friend pointed out that if the foot is reversed, it will interfere with the body of the Olympus EM1X. He's right, the protruding grips of the X don't allow the reversed foot to rotate freely. Although it won't balance as well on the Mono-gimbal, I put the foot back in its original position facing forward. The good thing is that it's easy to put it in the position that works best for you. :-)

見た目も作りも収まり感も良いが、縦位置にするときに全くスムーズではない。それ以外は気に入っていただけに残念。
