it will not stay on focus ring- so I guess it for zoom only. Good question- if people can get it to stay on the focus ring they must have a wide ring. wont stay on any my canon lenses.

It can be either. It's simply and Zip-tie with a lever arm. You can remove it simply and relocate it on which ever ring you choose. Very cheap and easy form and function. I've liked it so far.

yes! i use kmeye. it works great and to zoom all you have to do is pinch your screen in and out on live feed. hope this helps.

Auto-focus only. There is a wheel to zoom, but that is the only interaction with the lens.

Worth every penny. No matter if you manually focus or zoom. Set your camera to how you want the shot to look first. This device is to prevent shaking or blur while moving. Every time I use it I get the shot I need. I hope this helped.

Zooming doesn't always work, it depends on what program you're in. Some will zoom in/out if you use your thumb and index finger. Others will do nothing.

The viewfinder does indeed zoom with the lens - I got the camera out to check. It works really well. The only time I notice that the viewfinder and the lens can get out of sync is when you're vey close to a subject (e.g. in a macro situation) and there's parallax. In such (macro) cases it's best to rely on the screen on the back.

The 3.8 version has a smooth or "declicked" aperture and also has teeth for the focus allowing you to use a follow focus rig. The follow focus can be nice on most lenses but with a fisheye lens, you don't need to focus much anyway. The smooth aperture can be helpful if your are moving from a bright (outdoor)to a dimmer (indoor) scene while continually recording and wanting a smooth transition. In short, the 3.5 is more aimed at still photography while the 3.8 is more aimed at video.

No this device does not have a zoom and focus. All fixed setting.What are you looking for in terms of the focus and zoom?

As far as I know, you control the zoom function by standing on a ladder (assuming the camera is mounted high) and using the zoom control switch located on the base of the camera to zoom the camera lens. There is no provision for controlling the zoom function like a true tilt, zoom camera from your computer, etc.

Yes. Zoom and Focus are manual with the inner ring for the later. It s a little bit to freaky not so gradual control. Its endless so no physical connection with lens I guess.

Yes, both. Clear crisp view. Not sure zoom feature great, most of the time there all the way up

Yes. I just tried it. You can also focus with the ND side to side switch. Also, like ryuxis stated, the zoom is considerably slower.

From my understading they are both the same an have autofocus but you have to zoom out by either moving away or zoom in by getting close to the subject.

No. But you can use manual focus, or with autofocus set on the center, maintain the focusat that distace by holding the shutter button half way. Alternately with autofocuse set on subject the focuse will follow the chosen subject with okay but not perfect results.

No you must first take a series of test shots, I use a target mounted vertically as a focus target then a ruler set at 45 degrees. For each of the the designated focal lengths 4 on my zoom, and for three different focusing distances. A total of 12 pictures. Then download and decide whether the lens focuses in front of or behind the target. Lastly you put the lens on the dock and adjust the focus slightly in the needed direction. Then repeat the process until you are happy with the focus. Although a pain, it took me three hours, the focus is MUCH better now.

Well the button on top has a little graphic of a camera so I would say you use it to take snapshots while using it as a camera... I have never used it for that and most likely never will because I use a program called Many Cam and it lets me take snapshots right from my the software. As far as focus is concerned, it is fixed focus and so far I have not found any issues with it. Much better than Auto Focus for sure.... it seems to do fine up close and also with distance... but also remember it does not have any type of ZOOM.... I have had many cams and this one is by far the best for my needs and also the cheapest. Hope this helps.

This is strictly for macro. Focusing on anything that isn't at the closest focal point is impossible. It is also recommended that you use a lens with a shorter zoom level. This is basically incompatible with my 250mm. I can only imagine how much worse it is with a 400mm.
