The Record Alum Hardening Converter from Sprint Systems is designed to add a layer of protection to films or to paper emulsions that can be easily damaged.

Unhardened emulsions can be scratched when wet or absorb moisture when dry. Adding Record Alum Hardener to your fixer will toughen the emulsion to be more resistant to scratching and water absorption, and will increase the archival permanence of your print or film. For paper, every liter of hardener converts 66.6 liters of diluted 1:9 fixer into a working solution. For film, it converts 33.3 liters of diluted 2:8 fixer into a working solution for every liter of hardener added.

Q: 5. hello; we are interested in the Slik 150, but want to use a larger ball head for a Sony A7s camera. Can the 150 ball head be removed and another installed?thank you, tom and marj green, los altos hills, CA

A: Yes, the standard ballhead can be unscrewed and another used. It takes a standard 1/4 -20 ballhead socket. Note that the tripod is rather light and might be topheavy with a bigger ballhead though. Just fine with standard head and mirrorless cameras with smaller lenses.

Q: 6. My first time buying a tripod. Does this work for Fujifilm XT2 with 16mm lens?

Q: 8. I am quite tempted. A Nikon D7000, a Nikon 70-300mm lens plus a speed light will be my max load. Will this thing hold the weight? Thanks.

A: If windy you might have a problem. I use mine with a small SONY HD camcorder and wind took it down but no damage resulted from hitting turf.

Q: 9. Can the pan and tilt head from the Slik U9000 also be used on this tripod?

A: No, the head from the U9000 is not removable.

Q: 10. Does the maximum height include having the center column raised all the way?

A: Yes, the maximum height of the fully extended legs is 50 with the center column at full-extension adding another 14 to get to the maximum 64 height. This is best as a travel or backpackers tripod for a mirrorless camera or DSLR with a compact zoom. I would classify it as light duty and perfect for micro 4/3 cameras like mine.
