I recently bought a Canon 24 f3.5L II tilt shift lens. This is my first manual focus lens so there was a bit of a learning curve, but it wasn't too bad. I must be doing something right because I have gotten some shots I am pretty happy with in terms of sharpness. This is a really good lens to say the least. My question is this:
When you achieve focus and depress the shutter halfway, you get an audible beep that lets you know you have achieved focus, or at least I assume this is what it means. I do my focusing using 10X liveview and if I've done it right I will get that beep notification most times. Often, I can move the camera around, shooting from different angles, different distances and still get the focus notification beep without doing any new focusing at all. It's like an auto focus lens sometimes!
Other times, no matter what I do, I cannot get that focus notification beep to occur. I can do the 10X live view focus process over and over and no beep. Does this occur because the focus point is on a very dark or very light surface like an AF lens? Is this a minimal focal distance to this lens? Some of the shots I have taken that have not had the focus notification prior to taking the shot have still seemed pretty sharp.
This all applies to the lens when used straight up or with shift, not tilt. The bodies were 5D II and 5D III.
