Canon EF Prime Lenses / Re: Canon EF 85mm f/1.2L II USM

Nice images.

Gary, in the third image where there appears to be ghosting in the bottom two OOF flowers ... is this normal? I've had the 85L II for a few months now but have not seen anything like this ... yet.

My WimberleyII Arrived today....AWESOME ;) Thanks everyone.

I bought the WIMBERLEY II and a cheap gimbal head on amazon(not as smooth as the Wimberley)

I'm going to return the cheaper  version: http://www.amazon.com/Opteka-GH1-Heavy-Gimbal-Supports/dp/B0071BIQZC/ref=sr_1_1?ie=UTF8&qid=1399066268&sr=8-1&keywords=gimbal+head


Good choice Dylan. The Wimberley II is a great gimbal. So now we can look forward to more BIF photos from you  ;)

I too tried out a cheaper gimbal but it didn't look very reassuring. There are a few hacks which sell here in India for cheap but there is no point if you are mounting gear worth + $6K on it - Safety first! Better to spend a few hundred more and get one of the best gimbal that exists.

Are there really two threads going on about this camera's AF pushing 20 pages now? 

Why can't people just agree to disagree, and accept the fact the 6D is a great camera for what it is - an entry level FF body with great IQ but with simplified AF.

Sometimes one tool is better than another based on needs/wants.

To put things in perspective, my SLRs are playing backup to my EOS M at the moment  :o

Actually there appears to be two threads going on.  One is about the 5D3 (the hostile hijacking of the original thread), the other is about the 6D (the original thread).  I've tried to agree to disagree, but that's not always possible.

Unfortunately there is not a satisfactory amount of practical information about specifically the 6D's autofocus, and how best to use it, in this thread.  I've tried to share my impression of its capabilities (and limitations) based on 13 months' experience and 15,000 shutter cycles, on my 6D.  I have used 8 lenses (9 if you count a TC combination) on it over this period of time.  I feel there are a few others who briefly contributed to this thread, that I could learn more from.  But they might have been soured by the thread's hijacking.

As for your DSLR playing backup to an EOS M, I'm not sure why that would be.  Whatever works for you.

Just to be clear, the OP in this thread DID ask about the 5D3 vs. the 6D.

+1 ... but then, you see what you want to see. Not that it is surprising though.

Well that would make the title of the thread misleading...it should have been "6D vs 5D3 autofocus capabilities, let's bust a hole in one while heaping fanboy praise on the other one."  That is what would not be surprising...And since you want to be clear, how about reading the context of what the OP was saying?  He said he didn't want quirky autofocus behavior with fast lenses, and yet said he also didn't intend to make a living from his photography.  That last part to me, was code for "I don't think I need to spend the extra 1000 Euros to get the better autofocus".  For my part, I posted a difficult shot in very low light with a fast wide angle prime lens, that achieved the focus plane I wanted, via focus recompose on the 6D.  A shot that the OP would never need to attempt, actually...The 6D has its quirks, and the AF sensor is its biggest compromise.  Everybody knows that.  To keep belaboring it, is silly.  But the first post in this thread by the OP, did not scream out a need to buy a 5D3.  Clarity is a wonderful thing.

Whatever Carl. TBH, I don't care what you think

+1 or +3 or wherever we are on the standard Eneloops.  They've treated me well.  I’ve been slowly using older ones to put in remotes and clocks and whatnot around the house.  They last forever in low power applications.

I couldn't find the link, but somewhere out in the internets some guy wrote up a pretty good page comparing major brands for flash use.  I don't remember the details but I remember being surprised that the high capacity batteries didn't (Eneloop and PowerEx) didn't really pack all that many more shots in over the standard Eneloops.  I wish I could find the page to confirm, but I remember thinking that the price hike on the high capacity version just wasn't worth the cost.


Probably this link ... http://www.slrlounge.com/the-best-aa-battery-for-flash-the-ultimate-practical-review-of-aa-batteries-for-photography

Hope this helps!

Lenses / Re: Canon's f/1.2's: What is really going on?
« on: April 30, 2014, 01:07:03 AM »
I have both - if I had to choose between them, I'll take the 85L every time :)

+1

+2

The 50's keeper rate is lower, but having owned the 50/1.4 and 50 1.8 mrk 1, I'm very happy with the 50/1.2.  Keep in mind you are judging the 50/1.2 to the legendary 85/1.2.

+3 ... but then the 50L isn't designed for sharpness anyway - Personally, I bought it for the bokeh and it excels at that.

I have noticed this happens a lot on this forum, more so than others, people theorise about something, somebody with actual experience comes along and says your comments might be theoretically sound but your conclusions are off by a factor of, a lot. The theorist then goes on and on posting, giving meaningless comparisons, ever longer lists of calculations and percentages to "prove" their point, meanwhile the poster with actual experienced gets completely pissed off and either leaves the thread or annoys any readers by trying to defend their position which actually answered the point.


One could be forgiven for believing that the above paragraph was written in the context of the Ancient Aliens program on The History Channel.  :P

Lovely picture!

You said "Light is language". True. So true!

Thanks rpt. The words belong to Joe McNally. I'm a big admirer of his work.

Lovely shots here!

+1 for putting distance between the subject and the background. Also helps if the background has smaller elements like leaves (and not cars...).

Thanks for the suggestions rpt. I'll keep the tips in mind when I shoot this weekend. Will revert with pics  :)

I got the Wimberley II last year because I'd injured my left wrist and couldn't handhold the 100-400 + 5d3 without suffering a lot of pain. Worked like a charm.

I've given the RRS Pano-Gimball a look and to me it appears to be a better Gimball overall. If not anything the fact that you can knock it down for storage and transport gives it a big +1 in my book.

Thanks a lot for the replies. I'll keep in mind your suggestions the next time I shoot ... can't wait for this weekend.

Slower is better.    At f/2.8, you're getting both motion blur and OOF blur in the background.  Here's one from a sunny day where I should have brought an ND filter, 70mm (with the 24-70 II), 1/40 s and f/18 (so the blur is all motion).

Thanks, I see your point.

BTW, do you also mean to say that a narrower aperture (than f/2.8) should be preferably used to accentuate streaking lines?

Another way to get more blur is the subject moving faster - but I'm not sure moms like it when you yell at the kids "faster faster"  :P

Haha ... I was shooting right outside my house and when I suggested this to my daughters, I got shouted down by my wife from the window above   :'(

As you were with IS mode II, and Servo AF with one AF point selected, put that point on the face before it gets to where you want the image shot, steadily hold that AF point on the face until you get to where you want it, then gently press the shutter, keep the fluid motion going right through the shot and after, like a golfers follow through. Lots and lots of practice.


I was actually in multiple AF point selection mode. The focus was on the faces of my daughters.

BTW, you got motion blur in your shots at 1/125s! I can see what is possible if one gets his technique right.


Try an external viewfinder - to enhance tracking over longer periods, just an idea.
 Or use a tripod if you can control the path of the subject in someways: With a ball head lock the ball and use the panning capability of the base of the head (e.g.).

 Never checked it both measures work ... just time for me to do that soon :)


I've never used an external viewfinder but I'll try to find out more.

I was actually thinking of camera mounted on monopod, used in sitting / kneeling position. I'm not sure it'll work perfect but may be worth a try.

1st photo looks good to me :)

Thanks Dylan!

for bicycles going slow like that i'd go with 1/15 to 1/30th

As for technique, it just needs tons of practice

first off brace your left elbow into your ribs and let the lens barrel rest on your left palm
next make sure you also keep your right elbow tucked in but dont squeeze everything too tight this will just add shake so be relaxed about it.
next make sure your stance is stable balanced and comfortable
to pan keep your legs and torso all firm and just use your waist to pivot.
begin tracking early and make sure your movement is smooth
i find with race cars you can get a nice smooth rythem going and once you hit the groove the keeper rate comes up



First off, those are excellent shots!

Thanks for the suggestions. I typically shoot with both my elbows drawn in but don't really remember how I was moving for these shots. I may have ended up rotating the camera in my hands and will be more careful as to what I'm doing next time.

It helps to put more distance between your subject and the background, less between you and the subject.  This magnifies the movement of the background to create more motion blur.

Thanks.

Now you've got me thinking. I'll try using a shorter focal length while at the same time getting closer to the subject and see what happens.

Can someone please explain dumb me what does focus at "-3ev" actually mean? Thanking in advance.

Exposure values were initially used to merely compare exposure settings, and settings independent of film speed. EV0 was defined as 1sec at f/1. In this context, it is assumed to be at 100ISO (ISO100, aka light value). EV0 light would require f/1 at 100 for 1 second or equivalent to properly expose. EV-3 is three stops darker, or f/1 at 100 for 8 seconds, or f/0.7 at 200 for 2 seconds, etc. In other words, it's dark.

Thx much. So 6d center point would focus better in low light?

As per the theory, yes.

However, I find that EV3 is the extreme of low light and I'm not sure what can be shot handheld.

I'm sure AF at EV-3 is useful to some people, but as far as I'm concerned I don't shoot too often in extreme low light. When I do, I (a) use the tripod and AF is pretty much irrelevant; OR (b) use AF assist with a speedlite. 

PS: I'm sure someone will come along denouncing me for not trying the AF at EV-3, but personally, I haven't found it too useful. I'm also yet to be faced with a situation where my 6D could achieve AF and the 5D3 could not.
