  • I am sorry for not doing a full video review after having this unit for more than a year. I have been busier than I care to be. I will try to give visuals for this short text version. It is overall positive stuff but I think worth mentioning how it all went down for me.

    I received my unit quickly and nicely packaged. I set it up and quickly noticed a popping sound from within (like air bubbles in oil smacking as they popped). I contacted TrusMt, and they were quick to respond. I was going to return it but the sound slowly dulled over time, and at some point became inaudible. Then I got busy and stopped using the unit for at least 6 months. When I finally decided to use it again the very low backlash had been replaced with sloppy backlash. Again I was considering returning it, but on a whim decided to put a drop of locktite directly in the center square (brass colored) in the middle of the hand turn mechanism. Problem not only solved but the backlash is truly non existent now, and if it returns the fix is quite simple. Just be careful where you put the glue if this happens to you since I am sure someone could misread my words and glue the gear box or something and end up with a frozen unit.

    To sum up this rushed bit of info. Very solid unit, with a nice feel, perhaps needing a tad more quality control, but out of two minor issues one was an easy fix, and one simply went away on its own.

  • I've recently received the TrustMT NF2 follow focus unit and have just got back from a big day in the field and could not be happier.

    Perfect size, no play in the gearbox (0% as far as I can tell), it fits my BMCC rig rod system (Zacuto 15mm) perfectly, drives even large and heavy lenses smoothly and with ease (e.g an old Tokina 28-85mm f4 zoom that weighs close to 1kg) and everything locks down tight.

    The only improvement I can think of is to put some adsorbant material on the central hard stop. There can be a clicking when the adjustable hard stops and the stationary stop come in contact. In any case, it's an easy DIY mod.

    The only other thing is that a couple of the parts are anodised blue, but I plan to homogenise the hardware on my rig (i.e. strip and anodise them red) sometime in the future, so it was never a deal breaker.

    Thanks to Vitaliy for getting this under way. Now if I can just decide which Matte box to get....

  • Just received the NF2 this morning via the deals page. Initial impressions are extremely good. Built like a tank, no play or backlash, wheel turns silky smooth, no problem with locking down on the rails (I use the fotga dp5002 rails also listed on the deals page). Researched long and hard for a suitable follow focus and for the money and my budget (especially via the deals, thank you Vitaliy) think this is a superb buy. Will report back when I've had more chance to use it in the field.

  • I've tried different rods and even some from Hollywood Camera and the FF doesn't no lock down on any of them. Now on a positive note, it locked down on every other "normal" riser or base-plate system I used while shooting with GH2's.

    I suggest to measure rods diameters (using good calipers) and tell me that you'll get. And show exactly were is the place that does not fix.

  • I actually praised both items and wish I could have kept them. Amazing quality for the price. Let's get our facts right.

    (Let's make it more correct. You wanted to use specific fixed camera base. And we also discussed why heigh of this MB is such as it is.)

    This is incorrect. I wanted to use it for the Industry Standard height which has nothing to do with a specific fixed camera base. This is something everyone buying that MB should know or any MB as a matter of fact.

    (As guy who had two of their FF and many rods (I think more than you had). I can tell you that reason usually is the rods. It is not FF fault. But other QR solutions may be can tolerate more difference.)

    So I think my statements are very valid. The more expensive support gear I buy, the less, the less expensive stuff works with it. Please notice I didn't say cheaper there. This is the best FF I've owned and wish it would work but it just doesn't. Tried it with a guys FS-700 rig too and had the same problem.

  • The first was the Cinematics MB which isn't made to industry specs (though it was a damn fine MB!)

    Let's make it more correct. You wanted to use specific fixed camera base. And we also discussed why heigh of this MB is such as it is.

    It seems as though the QR section that attaches to the 15mm rods will not lock down completely. It's just a mm or two off but it cause the whole unit to ratchet slightly.

    It is clearly not best FF in the world. But I think words can be slightly softer.

  • I know this is an old thread but I'd just like to post some updates as my gear evolves. I've used this FF for some time now with my GH2 and standard pieced together rig pieces without fail. Solid. But since I've switched over to BM cameras and higher quality support gear, I've found a few products that no longer work well. The first was the Cinematics MB which isn't made to industry specs (though it was a damn fine MB!) and now this FF. It seems as though the QR section that attaches to the 15mm rods will not lock down completely. It's just a mm or two off but it cause the whole unit to ratchet slightly.

    Still works pretty well but it doesn't lock down with more expensive, industry standard base-plates and parts. Bummer because I really liked this FF but when the Director from the last feature I worked on came over to look at my shot, he thought I didn't know how to secure my gear. Not a feeling you want to have on set :) Anyways, I'm sure it's fine for 90% of the people or more who bought it but I guess when you start to buy higher quality production gear, it's a expensive, slippery slope!!!!

  • @Vitaliy_Kiselev

    thanks for your fast feedback, I'll be ordering NF2 asap.

  • @vic20

    They have exactly same backlash. NF2 just has horizontally sliding platform, and in NF4 things are tightly connected to QR bracket.

  • I'm just about to order TRUSMT NF2 or NF4, but first wanted to know what's the difference between the two and which one has the less backlash? thx

  • I've received my TrusMT NF2 a couple of weeks ago and even when I've not made an intense use of it, I can tell for sure that it's an awesome piece of gear. Solid construction, fluid but not loose, almost NO backlash at all. I'm not very fan of the gears that came with the FF, but they're not bad at all. I totally recommend this follow focus unit. And also recommend purchasing through PV deals, since my experience was great, with very fast shipping too.

  • @RuhrCity what's a compatible but reasonable rig, for mounted on a tripod? Thx!

  • @jfilmmaker that combo goes pretty nince together...no needs to worry or blame about this gear (working several month with it and love it).greets

  • Hey guys, how's the compatibility of this follow focus with Voigtlander 25mm? Thx!

  • Came in to respond about my new NF4 FF, I owned the iKan FG model that came with speed crank and whip. And while those two accessories alone is what initially sold me on the unit over a year ago, the backlash on it is not usuable for repeatable focus.

    Well I just sold the iKan and bought this FF from TrustMT. Boy is it a night and day difference in backlash. Everything cranks down tight as everyone mentioned in regards to their updates and changes. A/B stops is the best thing ever, can't wait to rack focus on a slider for next gig. For the price I think this is hands down the better of the FF out their right now. The only other one I had eyed is the Lanparte that VK has posted. Now I need to lock my whole rig down to prevent micro movements from lens and cam body.

  • Sorry, can't answer that one.

    But I just want to tell all of you that TrusMT has excellent customer service!

    For the second time they went to great length to help me with adjustable arm problems, fast, friendly and efficiently. I want to thank Julie in particular, who took care of my issue and responded to my mails in a clear and timely manner.

    If a Chinese company cares that well for their buyers, it's leaving many sellers in the "west" far behind. Wanted to make that clear since there were so many complaints here about SLRMagic – obviously there are huge differences between individual companies just like anywhere else.

    Plus, the latest version of the adjustable arm has cured the slipping problem completely.

  • anybody know if the trusmt follow focus works with the SLR Magic 12mm.

  • @Vitaliy_Kiselev What adapter and lens support do you recommend?

  • the lens always bulges.

    It is not FF issue. I suggest to use lens support, good adapter, check camera base.

    I am sure that we had discussion abotu similar thing recently.

  • I have one problem with the Trusmt NF2 I just got today. It might be the rig I'm using, but locked down every on tight, when I pull focus with the Trusmt FF and gears the lens always bulges. I'm using a GH2, Canon FD lenses, Ciecio7 adapter(brand new), and Indisystems rails and rail block.

    And, how do you remove the hard stops?

    Also, @Vitaliy_Kiselev what is with those terribly photoshopped weights in that photo?

  • just to confirm that the new design is a HUGE improvement. just got an upgraded part and it works. it's rock solid now! can use my follow focus again! :) great service from trusmt... as always!

  • Yep, seems like they improved the only weak part of their FF.

  • TrusMT has redesigned the pivot swing arm so it does not slip, they incorporated tapered pins, see photo. I have the new part and it works! I would contact (Julie) telling them you would like the new part using the address below. Mine came within a week. This makes the Follow Focus useable. trusmt@gmail.com

  • By the way, why don't they just use rosettes in the swing arm? That's what Letus did to solve that issue. Only probably with the Letus is that silly caliper quick release below. Huge clearance issues with a solution like that.
