Wimberley AP-601 Quick Release Replacement Foot for Canon EF 400mm f/2.8L IS III USM
Key Features
  • Arca-Type Compatible Replacement Foot
  • Anodized 6061 Aluminum
  • Double Dovetail Design
  • Provides Rigidness and Stability
Designed for the Canon EF 400mm f/2.8L IS III USM lens, the AP-601 Quick Release Replacement Foot from Wimberley is an anodized 6061 aluminum foot that is Arca-type compatible for use with most clamps and heads on the market. By replacing the original factory foot, the AP-601 adds rigidness and stability and reduces flex and vibration while mounted on a head. Additionally, a double dovetail allows accessories to attach to the bottom or the top of the foot. The lower profile of the plate provides better balance when mounted on a head as well. If you're going to use the optional safety stop screws, Wimberley recommends using a clamp with channels, which allow the screws on the foot to slide back-and-forth.

Wimberley AP-601 Reviews

Nice but not perfect

By Eric
Rated 4 out of 5
Date: 2025-05-10

The two main reasons for choosing this foot are - Arca-Swiss mount, and lower profile (easier to pack). There is still enough clearance to use it as a carrying handle (I'm using it on RF 100-300 f/2.8), but the OEM Canon foot, which is much larger, is more comfortable as a handle (Canon has a smoother contour and rubberized padding - nice!). I would normally get the RRS foot, but they seem to be having problems keeping anything in-stock lately - long wait times. The quality of material and machining is excellent on the Wimberly - but the smoothness, polish and finish of the anodizing is always superb on the RRS products. I wish Wimberly would finish the foot in matching canon white powder-coat, since all the lenses it fits are also white...

Height adjustment for Canon EF 400mm f/2.8 III USM

By Jeffry
Rated 5 out of 5
Date: 2022-09-06

This device was purchased along with an Oben GH-30C gimble. When using the arca lens plate that comes with the gimble I found I could not center a Canon EF 400mm f/2.8 III USM close to the tilt axis of the gimble. It was off (eye balling) by close to inch. The Wimberley AP-601 Quick Release Replacement Foot for the above mentioned lens drops the mounting height of the lens which allows a closer adjustment to the tilt position of the gimble for the lens.

Do not see any threads for filter mount, how do you protect the glass from dust and scratches?
Asked by: Jay
The 400mm f/2.8 has no front threads, only a rear drop in filter. The front element has a protective front glass. The deep hood also protects the front glass from damage.

The Wimberley AP-601 Quick Release Replacement Foot for Canon EF 400mm f/2.8L IS III USM is incompatible with the Canon EF 400mm f/2.8L IS II USM Lens. Instead, get the Wimberley Replacement Foot for Canon 400 f/2.8 IS I & II and 600 f/4 IS I & II Lenses, BH #WIRFCAP604.

The Wimberley AP-601 Quick Release Replacement Foot for Canon EF 400mm f/2.8L IS III USM is only made in black. All other brands of replacement feet are black as well.
