5D MK III Sample Images / Re: In Like A Lion

I'm surprised that others living South of us in Ct haven't seen them migrating yet.  Maybe East Coast Birds are smarter :)   We live North of Spokane, Wa  about 47 degrees 56 minutes Latitude, well North of CT

I heard a "bird expert" on talk radio recently say that between 1-5% of robins don't migrate, they just stay all year.

mack...by the way, i've heard "he who dares wins" about a million times in the past few years...do you know what I mean by that or did you just like that quote?

348
this would mean that there are two different lexar 1000x cards, both at 150 read, but with 95 and 145 write.

AFAIK the 16GB card was rated at 95MB/s max write speed; but the 32GB and above were rated at 145MB/s max write speed.

Perhaps there were some slower 32GB cards released.

Phil.

yes...but the link i posted is for a 16gb lexar 1000x with 150/145?   

to add to the confusion, I'm pretty sure my lexar 1000x 16gb is 150/95 (from BH photo)

with that said, i'm still pretty sure it shoots at 30ish fps before slowing. 

(after rereading what i wrote earlier i realize that the question about RAW image quality setting was N/A)

349
I just ran it again three times with all settings turned off and just the body cap on the camera shooting RAW - 23 frames on the 1000x Lexar, 35 frames on the 1067x Sandisk.  This is the number of frames on the 5DIII before it begins slowing from the max frame rate.  Yes, you can keep shooting at a reduced frame rate and eventually it will slow even further, but I'm measuring (and interested in) the number of shots at full frame rate. 

Also, given these results, I can confirm that aberration correction, vignetting removal, and standard levels of high ISO noise reduction don't impact frame rate.


mack..I didn't leave the body cap on, I shot at a a fixed subject - large RAW - I'll also try it again and check back.   do you have image quality set at "10"


interesting...

edit...I wonder if this is the reason for the diff....from Adorama website:

Lexar Pro 1000x 16GB UDMA 7 CF Specifications
Capacity   16GB
Read Speed   1000x (150MB/s)
Write Speed   Max 966x (145MB/s)
Compatibility   UDMA CF and CF devices

this would mean that there are two different lexar 1000x cards, both at 150 read, but with 95 and 145 write.

2. Lexar 32GB 1000x (LCF32GCTBNA1) UDMA7 - 150MB/s read / 95MB/s write rated
23 frames until buffer full

Strange, both of the 32GB 1000x Lexar cards I have will do 32 - 33 frames before slowing down on my 5DIII.

(I'm assuming by 'buffer full' you mean when the continuous frame rate drops from 6fps.)

Phil.

Same for me.

Lexar 1000x will go to about 30 before slowing  down on my 5d3.

And here are a couple from the seats at the Nashville Predators-Winnipeg Jets game last night. 200 f2.8L II, ISO 2000, 1/1250 sec. @ƒ2.8, AWB.

eli...you have some nice captures here.  one suggestion, crop some of them(not all) a little bit more.  if you're producing images for the web or for small print, then cropping brings us much closer (like having a front row seat) to the action.

example, after cropping your photo...

only trying to provide constructive critique...nice shots in general!   :D

first time shooting snowboarders....only shot for 15 minutes(i'll go back when it isn't -20 F wind chill) but came away with plenty of keepers.

these kids go flying through the air doing flips and 360's....great fun for a photographer. (and plenty of light with a natural reflector underneath them - snow)

Excellent pictures. I am sure it was fun. No chance of that here in western India.  :)

  ;D..yes, I bet you're right.  I just looked at my 3 day forecast...it's going to be -20 celsius for another day or two so YES, the snow definitely won't melt.  :'( ::)

85 L II. Couldn't decide if I wanted the the two bottom elements there or not, but waited a while for them to drift in, so I'll leave them there, lol.




hey viggo...I like the bottom elements in the pic...very serene!

crap...oh well, I'll sell my 1Dx on ebay and get the D4s....darn it.   ::)

Good luck with that.  Now that the D4s is out, the 1D X won't be worth much...   :o ;) :-X

Software & Accessories / Re: need help choosing the right macbook.
« on: February 27, 2014, 06:36:42 PM »
Thank you everyone. I decided to go with the 16gb. I appreciate the advice. I didn't want to have any lag or issue if I have multiple software open. Thank you once again

good choice....i went with the same 13" mbpro retina but with only 8gb ram....it runs great with only 8gb so I imagine 16gb will help future proof it a little more.

Lenses / Re: 24-70/2.8 Canon or Tamron: Which did you choose and why?
« on: February 27, 2014, 05:55:34 PM »

Tamron's VC or Canon IS will not help with people photography in dimly lit indoor situations ... coz people move

At say 50 mm focal length, with adults "trying" to pose and not move, what minimum shutter speed would be typically required for subject motion?

Looking over my shots, I actually got some very sharp photos at around 65 mm at 1/30th. 
Some of the moderately blurred photos were for example 61 mm at 1/16 th !  Didn't even realize how slow shutter speed was due to trying to run after people.  So in these situations, IS/VC would not have helped anyway?


It would help at those slow shutter speeds, but it doesn't help if people are moving...only if YOU are moving. 

regarding your question about at 50mm focal length....I would say shoot at 1/100 for sharp shots without IS...if that requires you to bump up ISO to 3200 or 6400, so be it.   The noise is easily removed in post processing, or if shooting JPEG, the 5d3 does an awesome job at noise reduction if you turn it on in the camera settings.
