I have a Canon 70D with an 18-35mm ART from Signa attached, a very massive and heavy lens and this ball head takes it without issue. Based on this, I can take 99% of camera / lens configurations of enthusiast photographers!

Bought it to use on my Sigma 18-35mm f1.8 lens. It's great and I've been using it on vacation. Comes with a free lens cleaner which is an added bonus. The case is also excellent and protects the lens filters well. Highly recommended if you are looking for 72mm lens filters. The product is well made and has done a good job so far.

One of the best on the market. I use it on a GH five camera with the Sigma lens. It’s a must have.

Bought for a Sigma Art Sony 24-70 and the Sony 28-135 (with Step Down), it is now permanently on my lenses. Additionally, having an ND and a polarizer on the same filter is a really nice surprise, especially at this diameter. For video recording and holding at 1/50 or 1/100 in broad daylight, this is best. A highly recommended essential.

I think it's a well machined adapter that works very well.. I tried it on a M42 35mm and a 135mm lens .. I was surprised at the quality of images I was able to get on my Sony A7ii and Sony 6000... Well worth the investment.

Use the filter on my Sigma 35mm 1.4 and I am very enthusiastic. The filter takes the reflections out of the picture as intended. There isn't a great color cast or anything like that in most situations. Processing is very good for the price, so I can give a clear recommendation here.

The way I use this filter is by combining it with a fast lens like the sigma 18-35mm f1.8 art. I use this filter in combination with the fast apertures to blur out the backgrounds in broad daylight without letting too much light into the picture. If I want to make it lighter or darker all I have to do is turn a ring at the edge of the filter.

The only thing that gets me is when I turn it too much and it ends up unscrewing the whole filter out of the threading a little bit. But that's not a bad thing, its just a part of the experience.

I bought it 8 months ago. This has been, thus far, an excellent purchase.
