here are two I captured last night. Once again, I am still missing the eyes on one with my 50mm f/1.8. I cannot tell in the preview of my camera that the eyes of one is missed, so I do not adjust accordingly. So, I have to try an recover it in PP

as always, super cute! eyes - mathmatically speaking - the eyes need to be on the exact same focal plane -line the girls up so they are both parallel to your camera on the SAME PLANE --- focus on one eye and you should be good. The other trick is to go up a few stops which opens up the depth of field so that your focal place is deeper and closer to you both.

I think Tiger that you might benefit from a sb flash unit for your camera. that way you can have a deeper dof and still have enough light.

Yup, these look a bit underexposed AT so Bambi's suggestion is good. OR just choose a spot in your home or outside where there is enough light.
To tell if the eyes are sharp, take an exposure on your LCD screen, then zoom in. Check your manual for how to do this.

More light will be great and flash but what if we like to catch ambient light.What if we like to capture light how we see it.With add light or flash we drastically change scene.It is not possible to use longer exposure with bigger aperture for desired DOF?

I totally get your point here, Vyeko. That is when creativity comes to play. He can line the girls up on the same focal plane - no extra equipment allowed --- a pie tin can be used or a piece of foil, or a white towel.... all free and in the house..... The point I am trying to make here is, if you want exactly what you shot, then you either are happy with the results or think a little outside the box to get that light that makes all the difference.
