I'm really a novice when it comes to photography. This lens does not have silent focus. As far as weight goes, a DSLR is already pretty heavy, and this lens does add a bit more weight to it. However, you have to balance that w/ the fact that you will most likely only carry around this single lens since it has a much wider range.

It has good center sharpness down to about one foot. It still gets a focus down to about 7 inches, and you have to look very closely to realize that the sharpness is falling off a bit. Any closer than 7 inches, it does not focus at all, as far as I can tell.

It plays and feels like a piano keyboard. I would says it's more weighted than sensitive. I hope that helps answer the question :)

There is no focus. It is just a magnifier of your view screen. I love mine. Great for a sunny shoot-bloks out excess light so I can see my screen.

It isn't heavy, not sure of the exact weight. Has a high , medium, and low setting. FYI - I love it!

It's very quiet. It's not very big so it doesn't click or move. Consider it "Stealth"

No. It is high and low intensity. The focus is always the same. Press button once for high, tap on button to switch back and forth from high to low or low to high.

The red light is noticeable if looking directly at the camera but that's all. It is not very bright so it does not draw attention. The camera is silent as far as I can tell. To test the camera before I set it up outside, I put it on my mantle at home. It snapped pictures for 2 days and no one even noticed it was there.

I returned that product before I tried it, so I cant say how heavy it might be....It is a 5o oz Fill Weight, so it is quiet light, not really something that you really feel, I guess.

No, it is very light (no pun intended)! I like it, though I don't need all the light settings, especially the probe light. Who would use that? The ONLY complaint I would have though is a catch 22. I like that you can rotate the light down at different angles and I usually have it tilted one notch but when you look up toward the ceiling the weight of the light pops it back flush with your head, so I would say if there is a lot of movement while wearing it, you won't use the tilt feature.

no, and it is not worth worrying about. it is a poor light, no focus, no swivel, no clamp and not very bright. consider it a freebie, and worth only what you pay for it.

It's very quiet. If it's cranked slowly it should be nearly silent. It won't bother anyone.

It is not heavy. It does have a very tight beam, that is useful for distance. Up close not as good. So if the cattle are out in a field would work good for you. The model I have takes batteries, or has a cord to plug into a cig. lighter plug. Another model is rechargeable.

I would say passive. And man what a totally awesome machine! You could get a more expensive rig, but why? This one does it ALL!

Very quiet. Only a light fan noise. i've never even noticed it when editing.

It is a quiet unit. Noise has not been an issue. The only draw back I have with the unit is the darkness of the 3-D which I understand is not unusual in the industry. There may be some that allows more light. Regular 2-D imaging is real fine.

I would also say it weighs a pound or less. The light part also broke off of mine. I really liked it, and it was handy having the light when I took the dog out at night, but it is too flimsy for me.
