Battery life could be a little better, but not bad since I'm using the led lights for every shot in microscope mode.

Even the little LED lights are too bright and create terrible highlights that ruin the color and contrast of shot..

I always sit under the brightest light I can find and check the door seals with a magnifying glass or one of those Jewelers round lights with the big magnifier

It gives good light for close-up flash work

If you use the flash, you end up with harsh lighting

Granted most people won't have one of those available to them but a really good light and magnifier work almost as good

Even in the best light about half of my photos are out of focus

With the LG-1 light guide you get perfect lighting up close
