Not Level

By Paul
Rated 3 out of 5

This base works great if only is was accurate. I noticed when making wide pans it was not level even though the bubble level indicated it was. After performing multiple checks I found the bubble level was not set properly. I removed the bubble level and reset it to be level and it works great now. I would rate it a two star out of the box for those who are not handy with fixing things and a four star after correcting the bubble level. Five star if it was good out of the box.

Does exactly what it is supposed to (with a caveat).

Does exactly what it is supposed to. For the money it is adequate for a leveling base with lighter cameras. It worked acceptably with my Panasonic GH5, Sony HXR-NX80 and FDR-AX100. But I had issues with my Panasonic AG-CX350. I had a hard time tightening the base so the CX350 would not flop when I lifted or carried the tripod to a new location. When I did tighten it enough it was very difficult to loosen to re-level the camera. I found the lever/handle to loosen/tighten this device to be kind of a pain to use.

Nice small leveling base

By Dave

I needed a small leveling base so that I could level a video head without having to endlessly adjust the tripod legs. This one seems well-made and performs adequately for my purposes. Since this is a small component with minimal contact surface, keeping the load balanced is the key to success. Unbalanced long, heavy lenses will be unstable and creep. My only issue is a small amount of left/right monkey motion (slop) between the top and bottom halves of the unit, with everything fully locked. I'm only talking maybe 1/32, but it's annoying nonetheless. Be sure to use the three setscrews to anchor your tripod head to prevent pan action from loosening the components; ditto for the base-to-tripod column connection, if your column head base has a similar securing arrangement. All-in-all a good value.

Reasonable leveling head, but not perfect

By Gary

I got this as a replacement for a ball head on an astrophotography tracking mount. I wanted something with a lower height (to reduce the torque on the mount) but with at least some ball head like adjustment. +/- 10 degrees of tilt with full rotation was all I needed, so this looked perfect on paper. I received it just before leaving for an astrophotography trip and on receipt, within a few minutes of trial use, the inner mechanism became unscrewed and the head was useless. I considered returning it, but the need for my trip was paramount and there was no time to turn around a replacement. So I fixed the unit myself. The issue turned out to be too little thread locker on the inner thread. I was able to fix this and the mount it now OK. It is a little “bumpy” in use as the grip the inner dish washer has on the outer housing varies with angle, so the unit isn’t as smooth as it could be. But for the cost it’s an OK head.

Unfortunately broke after 6 uses

If it is longevity and quality you are looking for, skip this product. After 6 uses the tightening mechanism striped and is now useless. I would recommend looking at one of the butterfly tightening bases as they rely on a different and stronger method of tightening.

Failed out in the field

Mine failed in the field after about 2 months of use. Tightening down the screw no longer locks the base in place.

Suits The Purpose Well

By Edd
Rated 4 out of 5
Date: 2020-09-30

I wanted something more 'low profile' than a full ball-head and this suits the job exactly. Well made and easy to manipulate - but never too loose, so it takes an adequate amount of pressure to adjust the base. Out of the box fit for both my tripod and my Kessler Crane Kwick Release Receiver! Handy that the adjustment knob is able to be popped out and moved out of the way if needed (a bit like a ratchet). My only suggestion would be that the adjustment knob have more of a bowtie head instead of the single sided type.

Failed out in the field today

By Derrick

I've used this leveling base in the field a handful of times. Today I hiked up a very very steep hill for about an hour. When I went to setup I found I couldn't lock the base in position. No matter how hard I tightened the locking nut the base would always slide out of level. Very frustrating to put all that physical and mental effort in to have a piece of equipment fail during my shoot. I will be contacting Sunwayfoto about it but even if they fix it, I won't have confidence taking it into the field again. Up until this point, I had been happy with it. Not any more.

I have a flat base tripod head I want to attach to this but the specs read 1/4th inch camera mount. Does it come with a 3/8 bushing to mate to a tripod head?
Asked by: Anonymous
Just got this unit and it did come with two bushings!

There are several comments about the grease used on this. Does anyone have cold weather experience with this? Sometimes cheap grease is totally unworkable in cold (0F) temperatures and if it isn't serviceable the grease can't be removed and replaced with something better.
Asked by: Stuart
I have used it in below freezing temperatures over two dozen times without any issues.

I intend to mate this with a Manfrotto 3221WN and a Giottos MH5000 3 way pan head. Are all these components compatible with each other?
Asked by: Clifford
Sorry, but I can't help you. I returned mine because it didn't operate smoothly and it was too easy to get lubricant on my hands and subsequently on my gear.

Can anybody tell me if this unit will fit a Sirui tripod w2204 weather proof with a K20X ball head or any of the 2200 series, and what had been your impressions if any, thanks.
Asked by: Alfredo
I have the W2204 + other Sirui gear. The 2200 series takes the smaller Sirui levelling base. As I understand the RRS TA-4 is for much larger tripods lacking the central column
