The Hejnar Photo F62AB clamp is an updated version of the Hejnar Photo F62A Quick Release Clamp (Reviewed back in 2011) which in turn succeeded the Hejnar Photo F010A Quick Release Clamp being one of my first reviews.
More or less the updated F62 design and specifications remain the same with the original F62A clamp but for the almost glossy black anodizing and the full laser engraved decimal scales.
The major reason for this short review was to create a reference page for the latest and updated version of this strong clamp, as it appears and will appear in various other reviews.
The clamp
The F62Ab clamp of this review came packed together with the Hejnar PHOTO MS-3_8 Linear Motion Macro Focusing Stage (Review). Otherwise it comes in a padded package accompanied by one 1/4"-20 screw, ½" (1,27cm) long and one Allen Hex key. According to the standard Hejnar coding the "A" after the model name stands for the short knob version and the "b" for the black anodized knob.
Comparison with Original F10A QR Clamp
Mounting on a Macro Focusing Stage
This is a nice example of utilization of all three of the mounting holes of the F62Ab clamp, since utmost rigidity and stability is needed for the purpose. More details about the clamp usage may be found in the concurrent Hejnar PHOTO MS-3_8 Linear Motion Macro Focusing Stage Review.
Mounting on a Ball Head
Mounting examples depend on the ball head design. The F62Ab QR clamp can be mounted on top of a ball head stem either by screwing it directly on a 3/8" as below...
Arca-Swiss® Compatibility
The F62Ab quick release clamp, besides the Hejnar PHOTO own rails, was also tested with various camera plates and lens plates, as well as with multipurpose long rails of various thicknesses and widths. Plates / Rails tested were from Benro, Kiwi Fotos, Fotoporo, and Marumi with excellent results.
For the readers that like numbers, I hereunder quote detailed measurements of the clamp Jaw dimensions, so as they can decide whether this clamp is compatible with the dimensions of their plates or rails.
All dimensions fall within the average limits, consisting this clamp compatible with almost any Arca-Swiss® type plate and rail.
Pros
Very nice sturdy and dirt-proof design.
Very precise machining, very good finishing and anodizing.
Excellent geometry and compatibility with almost any plate or rail with Arca-Swiss® type dovetail.
Excellent clamping strength with large clamping surfaces.
Good value for money.
Cons
None found at the time of review.
Conclusion
As the structural components of the updated F62Ab are the same as with the original F62A, little to nothing need to be changed in my conclusion. It remains a very strong and sturdy QR clamp, with large clamping surfaces with adequate contact area, designed to support heavy loads in any orientation very effectively. Vertical clamping which is a quite stressful task for other clamps is a breeze for this one. The extra detailed decimal scales add some more versatility.
Although Chinese QR clamps are invading the markets with very low prices the F62Ab a fully recommended top clamp.
I hope you found this reference useful, thank you for viewing.

Comparison with Original F10A QR Clamp
Original Hejnar Photo F010A QR Clamp (review) on the left and the most updated version F62Ab QR Clamp on the right. A lot of progress in the design of the side recesses, the deeper safety stop relief grooves and the more detailed laser engraved decimal scales. The 5 white lines (index marks) at 1cm intervals on each jaw are replaced with a laser engraved decimal scale at 1mm intervals and larger marks with digits in 1cm intervals. The numbers are increasing from the center (0) outwards. |

Using the provided Allen hex keys shown in the previous photo, it is very easy to mount and tighten the F62Ab QR clamp.in any orientation. Either perpendicular or parallel to the focusing rail axis. |

Where a Desmond DBH ball head is used as an example for the illustration. All in all we need is simply to screw-on the F62Ab utilizing the center 3/8"-16 threaded hole. |
In this case the ball stem should be equipped with anti-twist bosses and a threaded hole like the Triopo RS-3 ball head (Review) pictured in the above illustration, the F62Ab QR clamp is attached using an M6 flat head screw with a hex socket. |
The clamp is simply aligned, centered and fixed in place securely, just by tightening the flat head screw with a 4mm Allen hex key. |
