A reviewer says "most professionals would never use auto-focus". How would pro-shooter quickly switch from an object at 200ft to one that is at 10ft?

If you have time to set up the shot first, you could practice changing focus, keeping track of where your fingers are at either end of the shot. If not, you might have to zoom in very quickly, get focus, then zoom out quickly to the framing you want. If you have an assistant, they could handle focus for you (small piece of white tape to mark both distances on the focus ring). Auto focus tends to be more of an issue in low light.

You'd just have to know what M# is for 10ft, and what M99 minimum distance is, so that anything beyond that distance will be in focus. Trial, error and practice.

This is autofocus, the othe is manual and is impossible with a long lens. As outrageous as the price, it is the only one that works. I tried them all.

I've had one of these for a year, now, and am ordering another. Yes, it will focus clearly on an object at 6ft, and beyond! I have not tried it for portraiture, but have many times used it instead of my $20,000 Nikon equipment for micro-photography, and every picture has been good enough to enlarge to poster-size. I have been a pro photographer for decades.

One can set it to auto or manual focus on the lens and it's easy to go from one to the other. Also there are settings for stabilization settings and 1.5 meters to infinity, or 3 meters to infinity, handy if there's a fence in the way. I love this lens.

I answered incorrectly. I was thinking of the 24-105 L lens, which is the pro version. This lens will be fine, but, as I said it'll have a different range.

Not well quite simply. The maximum lens aperture is not a small enough f/stop number, you will lose autofocus and unless shooting in very bright light on high contrast subjects even manual focusing may be difficult.

One thing that hasn't been addressed by others, is that the APD version won't work with phase detection autofocus, so not only its it "slower" with light gathering, but also slower with focusing. And it's $500 more. Unless you're shooting in a studio, I don't think most will be interested in this lens.

For some reason, Canon seems to use FULL TIME Continuous AF - which is active even when you're not touching anything - and turned it on by default. Very annoying feature. I didn't realize this either until I popped on a noisy EF lens and it just wouldn't stop auto-focusing. I suspect Canon decided this would somehow make the camera "easier to use".

mmmm it doesn't have a preset for shooting no, but put it in aperture priority and you're good to go. with this camera, you don't want presets. hard to explain unless you;re holding it and using it. i'm shooting pro with this baby with the 70-200 2.8 and it's a dream. i do wish it had more focus points and i don't like the card slot at the bottom of the camera. not deal breakers, but it is a little annoying at times. at the end of the day, the photo is what matters and this camera is truly helps me take stunning pics - every time. i've had this camera since december.

The lenses are manually operated there is no auto zoom or focus. It would be difficult to catch action shots but it all depends on how fast your fingers can make it happen I guess.

you just need to set it at 100 ft afther that you can change focus without the need to set the scope again

I have the II. It has no switch. I've used it in auto focus only and I've never used it for video.

Unfortunately, the focus to infinity is not available: 2.5 - 3 meters (8-10 feet) is maximum.I use this converter with Nikon D5100 and with the specially adjusted, the old Russian lens Jupiter-9.http://cameras.alfredklomp.com/jupiter9/This is a very specific lens.https://www.facebook.com/photo.php?fbid=10202107820475164&set;=a.3021099764648.2131658.1177290511&type;=1

I have this combo. Auto focus is very very quick at 150mm-350mm. Slows down little post 350mm. Focus from ~ to minimum distance is OK at mm, but from minimum to infinity speed at mm is very poor.

Yes, this lens does have the option for auto focusing. But I clearly find that manual focusing is the better of the two choices. Unlike some lens, this option to change from manual to auto focusing is done by sliding the forward most ring, the one closest to the len's end back and forth. No switch. There is no automatic zoom option. You have to rotate the ring closest to the camera body to zoom in and out. I guess that is why I prefer the manual focusing. But either way, I am very happy with the photos I have taken with this lens. Hope this helps

I am Sorry i forget to Include this Information with My Response! Be Sure to Include a f-Stop Increase to being thing into Focus Also! This is Very Important Too! It is Something You Have To Experiment with to get Correct! Not Hard to Do, Just Use Live View on your Camera and Play with it from there! This Aspect is Very Tricky for Focusing and Experience will be Needed to some degree!

There are a lot of variables, the most important being the ISO you set and the lens you use. I've gotten shots at out to about 50 feet at a high ISO and with an F2.8 lens (on the FT1). With standard optics it's probably about 40 feet. I don't think you should use flash distance as the major deciding factor, though. To me the big advantage of the V1 is the 2.7x focal multiplier. A 30-110 lens is almost 300mm in 35mm equivalent terms. To get that on a D3200 you'd need a 200mm lens, which is big and heavy. Put a 18-200 zoom on the V1 with the FT1 adapter and it zooms out to over 500mm in 35mm terms, which is more than a 300mm lens on the D3200.
