Well this picture came close to what I wanted. I wanted a sharp focus on the eyes but I think I ended up with a little to much out of focus on the nose.  Having a gecko that wasnt moving around so much would have helped Olympus Evolt 500 ISO 100 Fstop 3.5 14-54mm @ 54mm

no tripod (I know that is part of the problem but its nearly impossible to use when shooting one of these guys)

Larger Fstop.

Question the question. Answer the question. Question the answer...

I wish I knew what I was gonna say :oP

and if that means you get a blurred pic - up the ISO so the shutter speed stays the same. You should be on something around 1/60th to get a decent non-blurred shot.

Assuming your distance might have been about 2 feet from the gecko, an online depth of field calculator give this:
Subject distance  2 ft  
Depth of field  Near limit  1.98 ft Far limit  2.02 ft Total  0.04 ft   In front of subject  0.02 ft (49%) Behind subject  0.02 ft (51%)
So, at f3.5 you have about 0.04feet total depth of field..only about 1/2 inch front to back!  Yes, using a higher aperture will help..meaning higher number and not wider opening.

At f/8 you would have a little over 1 inch...enough likely to get the nose!  : )  

BTW...the only geckos I see are cartoon characters...nice to see a live one smiling.
