QUestion for those that read "understanding exposure" by bryan peterson- howcome he used f/22 and even f/32 in some portraits printed in his book? Even the "who cares" apertures like f/8 and f/11 were used as well. Can someone shed some light on this? |

Not sure why he would stop all the way down to 22 or 32 though, at that point diffraction is kicking in and killing your sharpness. Granted it also depends on which lens i'm shooting with, but generally in the 70-135 range and sometimes as far in as 200, the depth of field becomes thinner as you get closer, so you would have to stop down if you're looking to get things in focus. Sometimes I want Bokeh, and sometimes I don't. |

I think you would have to play around and see what you like here. The wider the bracketing the more haloing you would get (if you like that effect).

I've seen a demonstration of diffraction with some excellent lenses, like my 500mm f/4, and it does really start to show it head at f/16 on many sensors, like the Canon 7D, with really high pixel-density. For wildlife and bird photographers, like me, it gets aggravated because we sometimes crop quite heavily to make the subject large in the frame. For landscapes, if you want to slow the SS, then stop down to f/16 and then add a ND filter if you need to get even slower. For an absolutely pristine image that can be blown up 200%, stop at f/11 and use an even darker ND filter. Dave

Wouldn't you know, it's supposed to rain for the next three days. That NEVER happens in Colorado.

Well, I was thinking that I'd be able to do some real high ISO testing, but FedEx says, "no one was home" and my daughter says, "no one knocked." Crapola!

All's well. I picked it up at the FedEx/Kinkos yesterday and I've taken around 2,000-shots already.
The 1D X's AF speed is in another world compared to the 5D MkIII and the 7D. So, I immediately put on the 500mm f/4L IS II and my EF 2.0X TC-III and started looking for flying targets. With my 5D3, that combo takes around 1-sec. to lock on, IF I'm lucky. I can lose focus in an instant and spend another second trying to get it back. With the 1D X, assuming that I've prefocused anywhere near the subject, it locks on in about .2-sec. So, here are some rough bird in flight keeper stats. where a keeper has the eye in focus, looking sharp at 100%:
It's worth every penny of the premium over the 5D3, if you can afford it. The high ISO performance also blows the others in the weeds. I feel totally free to shoot at ISO 3200 and 6400 in order to get the shutter speed that I need for the situation. Also, I'm freer to shoot at f/11 or even f/16 to get some extra DOF and still have a decent SS. Compared to my Series I 500mm, the S-II feels like a feather. It's only 1.5 lbs lighter, but I really notice it and appreciate it. I hold it in the ready position a lot longer. Dave

At the bottom of your picture in Flickr, there's an arrow breaking out of a box pointed to the right. Click on that, then select "Grab the HTML/BBCode. From the drop-down select Large BBCode, cut and paste here. Dave

Also, "Snapshot of the Day" is a more active thread and will get more views. You can post it there also, just this once. This thread is for questions and discussion relating to photography, which you had and maybe that's why you posted it here. Snapshot is a great thread, in it's second generation.

Dave,
I think your review of the combo made people question their finances. I like the part about the focusing speed, I could use that.

So why buy the S-II 500mm, because it's 1.5-lbs lighter and has two-stops stronger IS. So, buy the body first and upgrade your lens later. Big caution, if you don't shoot sports up close or indoors, or wildlife with big super-teles, stick with the 5D MkIII. In challenging situations, that demand high ISO, fast AF, precise AF and occasional bursts of incredible speed, the 1D X is king and it's not even close competition, but if you don't need all of that, then the 5D3's files are as good below ISO 1600 and almost as good at ISO 6400, it's AF is very, very good with bare lenses with native apertures at f/4 and f/5.6. It'll handle f/8 AF in a pinch, but don't expect it to lock on in one or two tenths of a second, like with the 1D X. I just paid for two cabins for a cruise from Venice to Barcelona, so mine will have to wait a bit, but I'm getting the 1D X for sure. The lens will follow, but I'm not quite in the rush that I was. The body is a sea-change and the lens is an incremental improvement. Dave

I wish I could upgrade my body. All I use is a Rebel XS, and it leaves a lot to be desired. Although, I have to admit, for not being very fancy, it does the job pretty well. Only have a few lenses, and would like to get a good fisheye, but don't really know where to start. I'm more of a hobbyist than anything so I'd ideally like something well priced for the product, but nothing too extravagant.
