Best 4.5 Cubic Foot Front Load Washer

This is a well designed and manufactured tripod foot. I was considering between Kirk and RRS and I went for Kirk because the knob design does not include a brass washer where it contacts the foot and happy with my choice. On the RSS LCF models, I find that the knob sometimes gets very tight and takes a lot of force to loosen and I blame the brass washer. CNC work is very good. Let's say it's at the same level as the best. Lever button which release the lock on the lens is well designed and locks with a satisfying click. You can't see it in the photo, but the button is shaped to stay flush with the foot profile, so you cannot see the button sticking out from the side. The only reservation I had was the plastic logo that sticks onto the foot. I would have preferred a laser engraved logo. My experience with these plastic logo is that it yellows out after years of use and may even drop out. But after mounting it on the lens, I don't notice it anymore.

Best for its size, weight, load, stiffness.

I purchased this product to replace the market lens foot on the Canon 100-400mm f/4.5-5.6L IS II USM Lens. The quality of the materiel is excellent and I would recommend this product. It fits all of the Arca style plates and is easy to install. It is a little bigger than the original lens foot, so it may take some getting used to. If your hand-holding the lens, it may be easier to rotate the lens foot to the top of the lens for better access to the zoom tension and focusing rings. Other than that, I think this is a great addition to the lens. See photo below.

I had one of these for my Nikon Z70-200 2.8 and it is great, this one is for my Nikon Z 400 4.5 as they deploy the same tripod foot. Very satisfied.

Great replacement foot for my Nikon Z100-400 mm f/4.5-5.6 VR S Lens. Was looking for a lighter replacement foot with Arca-Swiss compatibility. This is much lighter that the original foot and Wimberly plate combination.

This is the perfect foot replacement for my Canon 100-400mm EF 4.5-5.6 IS II. By replacing the lens's foot, the mount is much more stable than adding another Arca-Swiss plate onto the OEM foot to attach it to my gimbal. Expensive, but needed. There are other foots out there, but RRS engineers their stuff really good, it fits perfectly and very easy to install and remove.

I recently bought the Canon EF 100-400 f/4.5-5.6L and found that the lens is big and a bit unwieldy. The OEM foot is short and sits close which makes carrying the lens slightly more difficult (its more 'in the way'). Recently I replaced it with this one by RRS. The additional length of the base and increased distance between it and the lens has significantly improved the portability of the lens/camera. RRS products are well made and this replacement foot is no exception. I highly recommend this product.

This spotter is incredible easy. watch people hiking 4.5km away like there right in front of you crystal clear optics . I compared this spotter vs the viper hd 20x60 x85 and it gathers more light as the sun goes down well worth the extra money.

Recently bought a used 21/4.5 ZM lens. No caps. So I needed front and rear caps: front for daily use, rear for resale value. (I use Leica rear caps on all Leica, Voigtlander, and Zeiss lenses.) Excellent quality. Happy it was in stock.

Someone please tell me any other film washer better than this.
