Macro-Diecast blurr...

[canonEOS]

Hi! I'm a newbie here.I'm not quite familiar with thread yet but i'm trying to get into the flow line.My concern is, How can I take shoots without blurring the rear portion of the object? (Diecast car 1:18 scale or smaller)
enclosed photo is taken using a canon eos 5d markII
EXPOSURE: 1/30
APERTURE: f/20
FOCAL LENGTH:100mm
ISOspeed:800

This looks more like a question for the technique section, as it is about this type of shot rather than this shot specifically, so I've moved it across (and shrunk the picture to 800px wide - the maximum allowed by the rules).

You are hitting the problem of narrow depth of field. It looks like you are already at quite a small aperture but you could try going smaller still. You could also try moving the camera back a bit. You will reach a distance where you can get the whole car in focus and can then crop the result so that the car fills the frame.

What lens are you using?

First of all, .I was a bit excited in finding this thread in the web and forgot to resize the picture i post.I'm sorry for that.
I'm using a canon50d, and a Canon 5dmarkII camera. with the photo i post,i used a 100mm canon 2.8 lens...I got your point there sir, but do you think it also advisable to use a macro filter lens?

Using a macro filter will enable you to focus on an object that is closer and INCREASE the DoF problem. I think in this case you need to take a step back, not find a way to move forward.

As wulf has said, your problem here is your working distance, what a lot of people forget is that the distance between you and your object as well as the focal length affect your depth of field as well as the aperture.

A handy tool to use is this: http://www.dofmaster.com/dofjs.html pop in your body, lens, and working distance and it will tell you how much DOF you will get.

ok. Got your point guys.thank you very much..I was about a meter in distance & i just crop the pic to get a closer view. It somehow lessen the blurr & i need to practice on my exposure..enclosed picture is under/over exposure but less blurr in the tail end part.
