Hitech 4x4" Filter Holder (MK4) - THREE Slots with 105mm Front Threaded Ring (Requires Adapter Ring)

Comments about Hitech 4x4" Filter Holder (MK4) - THREE Slots with 105mm Front Threaded Ring (Requires Adapter Ring):

I like this product a lot, but it's not perfect.

Pros: well made, holds three resin filters plus a screw-in 105mm filter, using polarizers with grads is no problem, wide-angle filter adapters do not interfere with the use of all three resin filters at the same time, 4X5 hitech graduated filters have plenty of coverage (i.e. the filters are long enough so that the graduation line can be at the bottom of the frame), this is a complete system that can be used with many types of lenses and cameras and hitech makes good filters.

Cons: Be careful about vignetting (be sure to use wide-angle filter adapters on wide-angle lenses), you cannot remove resin filter slots to reduce possible vignetting, the 105mm front threaded ring stays on all the time, the filter holder secures to the filter adapters by pressure only.

I shoot with digital SLR's and large-format film. You can use at least a 17mm lens on a Canon APS sensor camera with a polarizer and without vignetting. With large-format, camera movements make this problematic. So YMMV.

The hitech system is a better alternative than buying filters for every new lens. If you shoot with a ultra-wide angle, consider their modular filter holder or their holders with fewer slots. Consider 90mm push-on lens caps if you want to keep filter adapters on all the time. If you use lots of filters at the same time, this is the holder for you.

I have a large set of Sinar 100mm square filters and 3 similar Sinar Filter holders. Recently I bought some Hitech and Lee filters which I could not fit in the Sinar frame. I had to buy this one and was amazed to see that it is almost identical, great quality. It can hold both my old Sinar filters and the new ones from other brands, even the 4x6" gradient. I just wished that there would be a provision for holding the 4mm thick glass filters. Also, as a copy of my old Sinar holders, I thought that the adapters could fit each other's brand, but nope, I had to buy a new set of adapters for different lens sizes. I also miss the provision for a lens cover that could fit the filter holder and other to fit the adapters mounted on the lenses.

Fit and quality are nice. With the problems getting the Lee Foundation kit and Cokin Pro holders, this is a great alternative.

I am an amateur photographer and I bought this HiTech holder in order to use 100x150 mm graduated ND filters for landscape photography. This filter holder requires that you also purchase an adapter ring that screws onto your lens. The adapter ring has a smooth flange that protrudes a few millimeters and it is this flange that fits into the holder. The holder has a screw that tightens against a band which squeezes against the adapter flange and holds it securely in place. This sounds complicated but it is actually very simple and it works perfect. Both the adapter and the filter holder are made of metal and everything is designed to very close tolerances. The filter holder (and adapter) are sturdy, well-made and there were no rough edges. HiTech filters fit perfectly and are easy to insert and remove. There is no "light leak" between the inserted filter and the camera lens. Neither the filter holder nor the adapter are expensive. I have read that any 100mm filter will fit although I have only tried HiTech brand. This is a very nice filter holder and I have no reservations recommending it.
