p.1 #1 · 6D AF tests anyone?


Many great reviews on the 6D IQ and Low light sensitivity but not much (as much as I would like) on the AF system.
Everyone says its no comparison to the 5DMKIII which was as good as the 1D MKIV (which I had and loved....) but is it good enough for some BIF shooting and sports (Paddling)
I am becoming more of a landscape and portrait shooter (when I am on vacations mostly..:-) and would like to bring just ONE camera that will do it all for me
I like the lighter weight and GPS abilities of the 6D though I do not want a camera with minor improvements over a 5D MKII which I already own (for now...)
Anyone have any pics of sports (something moving...) or BIFs with the 6D to show?
I guess I could go for the 5D MKIII but I think it would be overkill...

thanks

Ben

I've tried to shoot some BIF (with my puny skills) but there wasnt much flying..

Will try again... Seemed a little slow to gain initial lock (vs 7d, centre point) but tracked ok.

I tested it. The center point was good all around but I struggled with any of the other points. This makes sense as only the center point is cross type. I also have the 5D mark III. I did a test in the review of the 6D which is on my website: http://learningcameras.com/reviews/4-dslrs/91-canon-6d-review

Basically, it's not that the focus system is bad. It's that the camera only has 1 good focus point. The rest were hit and miss for me. If the contrast was good and the lighting was good, I had no issues from all 11 points. But any low contrast objects or bad or low lighting and the other points fell apart.

I also had a comparison with the 5D3 you may check out. If you are coming from the 5D2, I think there are things that will bother you with the 6D. You can find the 5D3 now on sale under $3000 too.

From what I hear; see the other 6D topics/threads in this forum, the center AF point is quite good, the outer points not so much. Check out Youtube, you will find a few very subjective reviews of the AF system. Below are three videos I found interesting...

In canon land, the ideal camera for that is 5D III.

I tried it out in Best BUy. Outer points were not very good. The building was well lit and I was trying to lock onto edges with a bunch of contrast....it struggled. D600 on the other hand was spot on. Unfortunately this is what is holding me back and having me consider the D600

The 6D cannot compete with the 1D3 and 1D2's in my collection as far as AF performance is concerned overall, so I'll be keeping my 1D3 for the foreseeable future.

Definitely different from my experience with my 6D. I posted this a while back in this thread:

http://www.fredmiranda.com/forum/topic/1171545/1

I tested the outer focus points in extreme conditions. I tried to focus at areas that have very very low contrast in very low light. In both situations, I'm pretty sure it's much much dimmer than Best Buy.

Picture 1: Rightmost focus point at the plain blue area of the restroom sign (to the right of the lady figure).

Picture 2: One of the outer focus point at the reflection of the big white grille of the windows on an LCD screen. It was after midnight. Outside was completely dark and the room was very dim.

One thing for sure is my old 5D2's would never be able to pick up focus in these situations.

I own both 5D3 and 6D. It's true that there is no comparison of these two AF systems, but I don't think 6D is bad. In fact, after using it for over a moth, I'm pretty happy with it.

Correct me if I'm wrong, but it I can't really find anything in focus in picture 2.

p.1 #13 · 6D AF tests anyone?


I recently bought a 6D, to complement my 7D, which I have used a lot for shooting youth sports and birds. The primary purpose for the 6D is landscape/portrait. I view is as a complement rather than a replacement for the 7D.

That said, I took it to shoot a CYO basketball game in the worst-lit gym in Marin County to see how it compared to the 7D. I was favorably impressed. Grandted, the overall operating speed of the camera was pokey compared to the 7D, both in terms of frame rate and speed writing to the card. I would not choose the 6D if shooting sports were my main use for the body.

But the AF worked flawlessley, using the center point, which is what I always used on the 7D for this purpose. The high ISO performance (ISO 6400) was probably about a stop to a stop and a half cleaner than the 7D. Being able to use ISO 6400 and get acceptably clean images enabled me to use my 70-200 f/2.8 in this gym, which focuses brilliantly, rather than my 50mm 1.4, which was my primary tool on the 7D in these situations, which was okay, but slower to focus and where the narrow DOF at wide apertures left less margin for focus error.

I found the biggest challenge was keeping the focus point on the subject. The selected focus point is not as clearly prior to the shutter being depressed as it is in the 7D, so it was easy to lose track of where the focus point was, exactly.

The overall keeper rate and image quality with the 7D and the 70-200 was measurably better than I had been able to get on the 7D, either with the 70-200 (too noisy) or the 50mm (limiting and unforgiving).

In sum, if you are considering this body as an occasional indoor action tool, while it's not a perfect body for that purpose, I think you will find its AF more than acceptable

It's a reflection on an LCD screen after midnight in a very dim room . The picture appears to be how I saw it at the time. You ain't going to find anything sharp out of the reflection, but I can assure you it's in focus and the camera was able to pick it up.

Everything in that picture was on the LCD screen. I was trying to point out the extreme conditions that I tried to use my 6D to focus and it did pick up. Basically, I wanted to see how much better the outer points did compared to my old 5D2. What's yours?
