Tanzania 2013Great shot yet again edward,would love to get my hands on a 200-400
1Dx 200-400f/4, Shot @ 560mm f/6.3 & 1/250th ISO800
Here is one from my new 85 1.2 before AFMA,turns out it needs +7 on the 1dx and +4 on my 5dmk3.
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.
Amanda in glasgow :-) Getting a little fed up shooting models now to be honest looking forward to a trip to budapest next month

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.
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...
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 aroundno 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.
personally i use phottix odins
they are not the cheapest but they are the best
the transmitter unit has a really nice large intuitive display screen on the back which lets you control all your flash functionallity and groups etc
they also allow high speed sync with studio strobes this is an undocumented feature but still pretty cool
one cool thing with this is you dont need the expensive odin recievers on the studio light you can just use a much cheaper stratto 2!
then you can mix speedlights and studio lights and do pretty much whatever you like and control the speedlights from the back of the transmitter, the studio lights you cant control as they are hooked up with the 3.5mm audio jack
Phottix also allows 2nd curtain sync off camera, which the Canon 600's cannot. Can someone explain how a 3rd party company can make a flash that can do that on a Canon camera, but Canon can't? ??
