Johnson Controls Pressure Switch P100

I use it with the P100 diffuser. It is stable and very easy to use.

I use it on my P100. Great results in studio environment.

These were the best things I found to organize my wire from my light to my pressure switch, would highly recommend these.

The remote pressure switch works very well and looks great! B&H is great to work with and delivered promptly.

Easy to use. Dip switch controls explained on chassis makes sense.

Works very well. The variable pressure zoom is perfect, and it has a switch for s - Sony and p - Panasonic, which are the 2 video cameras I have, and the switch works as expected. The record button works fine, but you do need to push it for a millisecond. If you hit it for a short time, it may not start recording. This may be the camera though, just something to be aware of. Overall, really great for simple remote zoom and great cost.

When you switch lenses under pressure, you don't want to waste time trying to also switch the filters from the old lens to the new one. This is even more important if you drop the filter, smudge the filter, sneeze on the filter, etc, etc. You can save a lot of grief by investing in enough of the Tiffen 812 filters to avoid this possible mini-disaster. I bought a couple of these filters when I was choosing the lenses I would use for a wedding shoot. It was wise to choose the industry standard in a warming filter. The Tiffen 812 is amazing in flattering flesh tones.

They are used on Sony DSR PD170 camcorders. The switch is pressure sensitive which allows you to manually control the zoom. I really cant say anything negative. They are exactly what we needed for a reasonable price.

I find the earcups very comfortable with even pressure all the way around -- especially making good contact below the ear. The sound quality is excellent for listening to acoustic and acappella music. There's no audio delay like you get with Bluetooth. The volume roller is so much easier and faster to use than buttons and is located exactly where my hand expects to find it. The on/off switch has just the right amount of delay -- long enough so I don't accidentally switch it, and fast enough so it's not annoying. Works out of the box on Windows 10. They even include instructions for how to remove the battery for recyling (which -- more importantly -- means I can replace the battery!) My only complaint so far is that I can't turn off the LEDs without installing their gHub software. But once they're out of warranty I may just fix that with a soldering iron... I'll be using these for all of my daily on-line meetings, and for listening to music.

I always clean my sensor with a cotton swab and sunglass cleaner, at this time was just a little dust and I use a cheaper cotton swab and It gets worse, usually, I use Johnson & Johnson brand and always work, I did this with 20D, 40D, 7D, 1DMKIV, 5DMKIII and now on 5DMKIV and always work...after some search I purchase it...I use the two big cleaners, one I wet and another I use to dry the liquid and after the second time it was like new, don't be afraid to scratch the sensor, for sure don't go through the sensor use pressure enough to move the dust away.
