Was looking at several articles about DOF calculations and was wondering about the term ' circle of confusion' or CoC.
Am trying to figure out the CoC of the Canon REBEL T3. As it sounds, I am a newie to DSLR LOL! Any help would be appreciated. Thanks
P.S. The lens I am using is a Canon EF 35-80mm 1:4-5.6 III, if that's any help.

Hello and welcome to the Uhh forum if you post a picture and check store original you will receive more help. If you are talking about the back ground in a photo an example would be very helpful. May I suggest going to the search feature at the top of this page and type in your question. Saying hello from Pittsburgh.

northsidejoe, thanks for your reply. Will have to check into it a little further and get back, ok? There's an app for Android tablets that can calculate the DOF for just about any camera and lens (so the ads say). Just trying to get a little more info, ok?

Just so we are clear here DOF and COC are two separate subjects. I think the search section would help in both your questions. I know members that use that app. and seem to like it. Post pictures ask questions and most of all have fun. Saying hello from Pittsburgh.

There is a nice app for the iPhone I've been using for some time.
"Depth of Field Calc" Some screen shots and Searcher is correct, .019 CoC for Canon T3.

Since you are a newbie, just curious if you understand what CoC is and why as a beginner you think its important to calculate it for your specific camera and lens. Is it just an intellectual exercise on your part? What are you hoping this knowledge will do for your photography?

Thanks for your reply, Searcher. The app I have doesn't show the CoC for the Canon T3. Apparently the app isn't as up-to-date as yours, but it was the only one I found for the HP Slate tablet with Android OS. I'll save the info on the computer to use it at a later date, ok? Since I'm a newbie at this, I may never have to worry about it, anyway.
I'll probably see more on this and other topics of great interest for the Canon Rebel T3 in the future. I'll be sure to keep an eye out for them. LOL!

mwsilvers; Didn't know if it was important or not. Right now, it's just I.E (as in intellectual exercise) although I'm far from being such in this case. Mainly, I'm interested in using the tablet as a remote control for the Canon camera. I wouldn't mind seeing some articles on this subject.

I don't have any apps, nor do I use Iphones, Ipads or the like. A web site you may wish to visit is http://www.dofmaster.com/dofjs.html
Where you may learn more than you need on DoF.

That's a great term, with amusing uses in all sorts of fields.

Who is the seller of this app? It looks a lot more comprehensive than the one I use. Cheers

Edit. Found it ..
