LockCircle Announces PrimeCircle, a Cinemod for Zeiss ZF and X-Circle, a Semi-Permanent F to EF Mount Adapter
I am partial to Nikon lenses, and I've often recommended them to many people for cost alone, but if you've got some money to spend, Zeiss certainly makes one of the best Nikon mount lenses. If you choose to cinemod them, you've got the next best thing to a PL mount lens. LockCircle, maker of the LockPort and the LockCircle Body Cap, is getting into the cinemodding game with some interesting products. The first is X-Circle, a semi-permanent lens mount that not only provides a solid F to EF mount adapter to the rear of the lens, but turns the lens 90 degrees to make the lens information more accessible. They also introduced PrimeCircle XT, a complete Zeiss ZF cinemod including de-clicked aperture, and PrimeCircle Ring Kits, a DIY lens mod that allows you to add a professional follow focus ring and standard 95mm front mount yourself.
Here's a description of the PrimeCircle series of products:
- Teflon Impregnating Hard Anodizing (TIHA) for heavy duty, scratch resistance and lifetime work.
- Innovative X-Circle Cine-Lock (pat.pend.) with improved locking mount for cine-style focus work.
- Exclusive SIDE INDEX VIEW (pat.pend.) for easy to read focus/aperture settings - EF Mount Only
- Ergo-Gear, innovative follow-focus gear featuring also handheld ergonomics grip.
- Front Mount with 95mm size mount for professional cinematographers matte-boxes and accessories
- Front Mount with circular engraved grooves for superior flare and reflection control.
- Filter thread 90mm for PRIME-CIRCLE 90 Series professional filters - coming soon
- Easy to mount kits with "step by step" instructions (RingKits)
- Side Code Barrel with engraved lens size - immediate lens coding for production crew reports (XT only)
- Custom Flight Cases
- PrimeCircle Ring Kits and XT with these Zeiss lenses: 18mm f/3.5, 21mm f/2.8, 25mm f/2.8, 25mm f/2, 28mm f/2, 35mm f/2, 35mm f/1.4, 50mm f/1.4, 85mm f/1.4, Makro 50mm f/2, Makro 100mm f/2
The X-Circle is a really interesting design, and it makes it a lot easier for the AC to check distance markers and adjust aperture if necessary. X-Circle will work on all Nikon lenses as well as Zeiss ZF lenses. PrimeCircle is basically their entire cinemod line of products, and the Ring Kits are the cheapest option. The Ring Kits include the X-Circle and EF back cap, focus gear, 95mm filter and front lens cap. You're going to need a separate kit for each Zeiss lens that you want to mod, as the focus gear and 95mm filter are specific to each Zeiss lens. The Ring Kits will run you $239 for just the filter thread and focus gear, and $399 if you also want the X-Circle F to EF mount.
The PrimeCircle XT is a complete mod of the Zeiss ZF set of lenses. They include everything from the Ring Kits, but also have a de-clicked aperture and a metal housing with the focal length of the lens engraved on the side. You can buy single lenses or an entire set with a flight case, but right now they aren't offering any way for you to send in your own ZF lenses to have them cinemodded.
X-Circle and the Ring Kits are both available now, but you'll have to contact LockCircle for pricing on the PrimeCircle XT lenses and len sets, as they don't list prices. I would imagine that the full lens kits will not be cheap, but for a professional option, they should compare favorably and be a cheaper option to Zeiss CP.2 lenses.
LockCircle is also developing lens filters, some of which will be compatible with a mattebox they will also be releasing. Check out all of their products below.
