This kit has exceeded my expectations! Considering the price difference between this kit and a similar kit from a “top-shelf” brand, I was pleasantly surprised when I opened the box and noticed how well it is actually built.
TL;DR: An excellent value; if you were thinking of getting a square filter kit, get this, and put the $300 you saved towards a better lens (or whatever else you really need to get that shot). One thing to note, you can’t use lens caps (if that’s important to you).
What you get in the box is a kit of hard anodized aluminum construction with grade 12.9 countersunk steel bolts, and misc plastic bushings and rubber foam components where appropriate. These appear to be cast (not CNC machined) which may explain some of the price difference [compared to a top-shelf kit]… the castings are very high quality and the average user would probably not be able to tell the difference. Build quality is very good.
Separate carrying cases are included for the filter holder/adapters and the actual glass filter itself.
Filters are friction-fit, and the housing can hold up to two filters at a time. Everything fits well and I was not able to detect any light-leakage.
No complaints about the included 10 stop ND filter. I can not see any noticeable color cast, ghosting, haze or chromatic aberration, nor can I find any degradation in sharpness. I do not have access to lab equipment that can test this filter in a quantifiable manner, but hey, if my eyes can’t see anything wrong after a dozen outings over 3 weeks of use, then I’m happy.
The only thing I was a bit disappointed about was the lack of provisions for the use of lens caps. You cannot use the lens cap that came with your lens once you thread the filter adapter, and no alternate is included with the kit. Not a big deal, but in some situations it would be nice to be able to remove the business end and put a cap on your lens.
Overall, I am impressed. This is an exceptional value and I think anybody looking for this sort of kit will be pleased at the build quality and performance that this kit offers. Highly recommended!
Tested using a Sony a7 II (full frame DSLM), Sony FE 4/24-105mm G OSS and Tamron Di III VC VXD 150-500mm.
Included test shots taken with the Sony FE 4/24-105mm G OSS. No post-processing on the 2 test shots except a slight adjustment (< 0.5 stop) to match exposure. The photo of the bridge was fully post-processed
