Technical Support / Re: How to use cf and sd cards Mark5d3
« on: February 14, 2014, 04:40:13 PM »
Hi all,

I'm just wondering what's the fastest SD card people have used and still get the speed benefit?
I remember reading there was a limitation/issue with the SD card slot of the 5D3 - does anyone remember what that was?

Thanks

Not updated since March 2013 but still informative...

You can see that there are fast CF cards and some that are slower than SD... You can also see that spending the money on a fast CF, and only writing RAW to that slot, will give you the maximum results... You can also see that, incrementally, the faster SD cards will still do a little better...

Me, I have (2) SanDisk Extreme Pro 32GB CF cards and (1) SanDisk Extreme Pro 64GB SD card... I write RAW + Large JPG to each card - I have never hit the buffer... Then again, I am not a spray-and-pray photographer - I bought the 5DIII because that second slot buys you peace of mind... Every shot is recorded in both formats to both cards - have never lost an image with SanDisk - cannot say that about Lexar cards that I have owned... YMMV...

Lenses / Re: Should I go for the 85mm F1.2L II USM ?
« on: January 11, 2014, 06:48:58 PM »
Not to hijack the thread - but I have a question for you other 85L II owners... Took my B&H new lens out of the box and ran it through FoCal - got a solid AFMA setting... Went to do the aperture sharpness test - I always go into Live View at 10x and use a Hoodman loupe with 3x to fine-tune the focus... The focus ring just spins - does not change focus or change the distance in the window - regardless of whether the lens was set to AF or M... Is there some trick to getting Manual focus on this lens? Thanks in advance!

Half press the shutter, so metering is active.  It's a focus-by-wire lens, so manual focus only works if the autofocus motor is powered.  If you like to store your lenses with the extending fronts retracted, you will have to get into the habit of retracting the front focusing element before you turn off your camera.

Thanks neuro! I was driving myself crazy!

1Dx 200-400f/4, Shot @ 560mm f/6.3 & 1/250th ISO800
Great shot yet again edward,would love to get my hands on a 200-400 :)

Born, look at your models! You want to stand farther away? :o

Here is one from my new 85 1.2 before AFMA,turns out it needs +7 on the 1dx and +4 on my 5dmk3.

Aye! That is one bonnie lass! Eyes like that should be unlawful on a beautiful woman - removes all sense from a man's head!  ;)

Love to see you using the 85L, born, that's my next piece of glass, lord willin'...

Question - how are you using that beast? One shot/focus & recompose or One shot/select AF point & don't move or AI Servo and let the camera deal with any movement?

Thanks, much appreciated.

You continue to post great images Edward. I can only repeat myself and complement you again. You should seriously consider a book. Make it a tutorial in safari photography, with lots of details on where you go, how you organize it, what equipment you use for the various cases and images etc. Most books I read about this topic are either focused on the travel side of it or just images. If there are stuff about photography, it is normally something for they guy who bought his first DSLR yesterday.
You write well, you have tons of great images, you have been all over the place and you have more equipment than most people can dream of. So seriously, instead of going back to some boring business, you should enlighten our lives with a stunning book, worthy of your photographs.

I was trying to talk him into actually organizing photo safaris - with a pre-planning workshop where he paid for all the beer...  ;D

Amanda in glasgow :-) Getting a little fed up shooting models now to be honest looking forward to a trip to budapest next month :)

Amanda by Lseriesglass, on Flickr

born - I feel for you, buddy! I know it can take a toll - looking through that viewfinder and seeing a non-stop procession of beauty - it must eat you up inside... You need a break - some time away from the Lassies - and I hope Budapest can provide some relief... Meanwhile, all of us here, we feel your pain... ::)

Lenses / Re: How many megapixels can these lenses resolve?
« on: November 12, 2013, 04:15:27 AM »
The simple answer to your question is as follows:

for any given region of interest, use the table of numbers of LW/PH

take that number, square it, multiply by 1.5 for the 3:2 aspect ratio
divide that by 1,000,000 if you want simple MP and you'll get the equivalent resolution if that portion of the measurement was uniform for the whole frame.

e.g.  center of 17-40 @ f/8 will = ~ 16MP

it's pretty sad when you calculate the corners!

If you measure the top level of the graph, ~3700, you'll get ~21MP which is the MP of the sensor in that body.

Thanks, Aglet, that makes sense! I noticed on Photozone that only a couple of Canon lenses could hit that 3700 value... Oh, and the Sigma 35...

Which leads me to ponder... I know Photozone uses a 5DII for their testing - if some of the lenses are hitting the top end of that sensor - would using a Nikon/Sony 36MP test vehicle let us really see where the lens hits its peak? Until Canon brings out their own high MP body, of course...

lens resolution is a misunderstood topic.... the resolution is not a hard limit, it is the point where the curve bends....

For ease of example, let us assume everything is full frame... Let's say you have a lens with 18Mixels of resolution. If you put it on a 10Mpixel body, it is capable of resolving 10M. Put it on a 15M body and it will resolve 15M. Put it on an 18M body and it will resolve 18M... but beyond this point the line changes from straight to a curve... Put it on a 20M body and it does not resolve 20M, it will resolve a number somewhere between 18 and 20... for the sake of argument, let's say 19.5.... put it on a 40M body and it might only resolve 35M... and so on...

Don, that is a great example, but where does one find the resolution numbers for a particular lens? It would be great if they stamped on the box "This lens has 25MP of resolution capability" or similar...

$1899? OK, I've never seen it this low... Pulled the trigger from B&H - Thanks CR! ;D

no remote second curtain sync is a deal breaker for me
here are some examples

Every single one of those "examples" would look exactly the same with first curtain sync, you are just dragging the shutter, it doesn't make any difference if the flash fires at the beginning or end of the exposure for that type of image.
I disagree I find the images sharper using second curtain as the sharp image is exposed over the top of any movement blur not the other way around

That's the way I understand it... My goal is to resurrect my wedding business and I have visualized shots with light trails entering the image and then "popping" the B&G PJ-style... Can't do that with 1st curtain...

Lenses / Re: AFMA for new 135mm F2
« on: October 31, 2013, 01:54:55 AM »
AFMA can vary due to distance... Common recommendation is to check at 25X and 50X focal length... But what drives your AFMA decision is your use... If you bought it for headshots - then you probably want 25X... If you are going to shoot indoor sports - then maybe 50X is better...

My 135L required -4 at 4.3 meters on a 5DIII = Every camera/lens combo is different... I'm not sure how you got it to work at 5 feet - you got a green "check" at both normal and zoom settings? Both are required for FoCal to do its best for you...

Unless you are in a really big room, and can drench your target in light, I would put it on a laptop. Go outside, put that target in a bright location, get your camera on a sturdy tripod, and run FoCal again... Look at the "Result Confidence" and your test chart - make sure you got a good run... Hope this helps!  :)
