Sam can smile all she wants! ;^)

[Himanshucisco1]

Nice tutorial

but Sam why are you smiling  ?? :P

[MrPlaystationboy]

@AlbertGabrielCo it means pointing the camera back to were you want it to be on the final image

[MrPlaystationboy]

i agree with @BMSWEB i also onley ever use point ...alll you do is point the camera at the thing you want in focus ..half press the shutter (or even more easy, use the AF/AE lock botton if your camera has one ) until you hear the double beep (or see the focus confirm thingy in the viewfinder) ...and then you re-compose ...it's alot more acurate then having the camera chose were to focus ..and i think its just as quick...if not quicker

[IraLWilliams]

How do you focus if there are three people? Sometimes it will focus on one person and then the others are blur.

[JCSolar]

Is she married?



[oesdoob]

How come in your example on canon 7d there are five option, on mine i can only select 3 out of five? Thanks Fort

[renecoignaud]

Thanks for this show and all others. I always enjoy them, and often learn things that are very useful and that I use a lot afterward.

[bacdoliljo]

If you tilt the camera to focus on her eyes and then tilt back down to take your shot, the plane of focus changes with the tilt so it's not really focused on her eyes anymore. You can only do this is you move the camera parallel to the plane of focus, focus, then move the camera back within the plane of focus to compose the shot to maintain the focus on the target... Right?

[corazonesnegros502]

Less talking Mark and more Sam. I love this girl!!

[76ers]

Holy hell Sam is soo hot... my Autofocus would never lose focus on her no matter where I pointed the camera. They'd just battle each other for Sam and automatically ignore Everything else around her no matter which focus point I chose.

Shoot... what did Mark say again? Darn it, now I gotta replay the video

[cofino78]

Hey Mark what lens was that on the 5D? was it the 50 1.2L?

[RFguy8]

Mark. Great job. Thanks.

[catalin205]

good show keep up the good work

[TeddyImSuff]

@ adoramatv you should tell people that the center focus point is usually the best to use. most entry level dslr only have 1 cross type focus point in the middle. you may also tell people that the faster the lense is, the better the focus normaly is

[MediaVisionHD]

autofocus for night night object moving?

[ny1fanta]

Sam says, "Hey Mark, I am back here!"

[sublimesangar]

I'm in love of Sam

[PhotographersOnUTube]

I covered the same thing in my Aperture tutorial. Mark does an amazing job explaining things. Even though I know most of the things he talks about but I still enjoy watching his videos. Teaching is also an art and Mark has mastered it. If you guys have any question, feel free to ask me.

[nate42nd]

I like Sam. Oh, and my 7Ds focusing system

[nate42nd]

I like Sam.

[dingo27mobile]

Thanks! I didnt even know i can do this!

[familyvids1]

Is it true that if you only use the centre focus and focus on the person (irrespective of where they are in the frame) and recompose then the focus will NOT be as clear as selecting the closest focussing point and then recomposing?

[rickjbradbury]

@familyvids1 Yes it is true, as you will need to move the camera further during the recompose, for portraits use the focus point nearest the eye closest to camera and then lightly recompose (not a big move) or you will loose critical focus especially using fast glass for example f2.8 or faster.

[shlomki]

hey new shirt :P

[onlineahmeds]

welcome back Sam ;-)

[3curb]

Thank you for choosing D7000!

[Madhack2004]

Excellent as usually. Thank you!!

[YinCreation]

The model just have nothing to do for 5mins.

[WiseGuy02]

@YinCreation Mark isn't silly. He knows most of the guys watching this episode had to watch twice. The first time we were just watching Sam.

[BMSWEB]

I only ever have my focus point set to centre. I just do the half click on the shutter and re-frame while holding down the shutter button. I've never actually used any of the other modes on the canon.

[markaurelius61]

@BMSWEB That's fine for static subject, but if you anticipate a moment with moving subject, the focus point is great. You get the composition sorted in your mind, set the required focus point, then keep that point on the subject till the right moment pops up and one click is all you need, meaning the delay is much reduced.

[ocabj]

@BMSWEB I have both 5DMKII and 7D. I usually center point focus and recompose for non-action. But if you shoot action, the zone AF on the 7D is incredible.

[JanErikEdvartsen]

@BMSWEB That could pose problems if you use wide apertures like 2.8 and wider. When re framing you could shift the focus place cause of the narrow DoF.

[essellar]

@BMSWEB With wide angle lenses or close subjects, that actually puts the plane of focus behind the subject. You'll really notice with a shallow depth of field. Hasselblad cameras, which only have the center point, have a motion center to tell the camera how much you've moved the camera to recompose, and then compensate for the focus distance change. Always use the autofocus point closest to the subject in the frame, even if you still need to recompose -- it minimizes the resulting error.

[BocaNejra]

@BMSWEB Yeah!! It's fun how the latest cameras come with like 20-40 focusing points and I wonder myself why??? Only one accurate one and the possibility of locking it as with the metering is needed. Its just fancy stuff to charge more for them! GWCs must love that LOL.

[donttrustany1]

Lyndon Johnson?

LOL.

[Snakekilla12]

thx for that Mark! I loved the last few words you've mentioned about just focusing on the subject's eyes and then moving to get the composition I want, this would work very well for me as I don't have the "Matrix" AF mode for my Canon T2i
