comment How do I choose between 24-70 f/4 and 24-105 f/4 Canon lens?
@MichaelClark .. thanks Michael .. seems like I will wait to wait a bit longer and save up for a f2.8 then :) I am using 17-40 and 70-200 for occasional weddings .. yes I do have problem with f4 even though my 5DIII has very good ISO .. especially in main ceremony, where the registrar doesn't like flash.

Thanks for your comment @Leandro .. can you teach me how you calculate that 47mm and 64.5 mm out of the lenses?

comment How to simulate different focal length and sensor size on an image?
@MichaelClark I don't know much technical details as you guys spoke .. my real life scenario is I have a 5DM3 and 200f2.8 lens .. I want to get closer for wildlife so I am thinking to buy either a 400mm f5.6 lens (or 2x teleconverter) or a 7D or both. So I want to simulate it how much closer I can get in PS first. But I basically understand DOF is something to do with bokeh. I can change aperture on my camera to control that DOF thingy. It makes me wonder when you say your above comment though. If I change ppi (pixel per inches?) in a image, why does DOF change?

Thanks for your answer. But it's more like you are teaching me how to use Photoshop. I know how to use Photoshop alright. What I don't know is how much do I crop to simulate that effect. For example, how much do I crop on a picture taken with 200mm focal length to become a picture taken 400mm focal length?

revised How can I get to 400mm+ for wildlife photography on a budget of around £1000 with a Canon DSLR?
