What are the ups and downs?

I love smugmug :)

I used to do free image servers and smugmug is just so much faster and 100% reliable. Photo storage is unlimited, and the basic membership gets you a 6GB traffic quota a month, which I'm having a hard time getting to.

There's a lot of convenient options to set up your galleries too. These guys for the most part thought up everything, and I've heard their customer service is really friendly and enthusiastic too, unlike places like pbase.

Well worth the annual fee.

Cool. thanks for the input.:camera::beer:

That's pretty cool, but
1. Why aren't you looking through the viewfinder?
2. I'd like the first couple a little better if more of the pen was in focus.

Actually, fuzzy, a reversed 30mm on a 180mm macro is 6x magnification.

Take the mounted lens and divide its focal length by the reversed lens focal length. 180/30 = 6.

I only have a 150mm macro lens and a 50mm reversed lens to use, so I only get 3x magnification, which is hard enough to shoot with. I can't imagine 7 - 8x...

Doh! Corrected! I knew the formula, just didn't do the math right :p

7-8x is absolutely nuts. A macro rail and perhaps a ringflash is pretty much a requirement.

1. I focused throught the viewfinder, so after that I don't need to look through the viewfinder (I was using a tripod).

2. Depth of field/focus is really really shallow at those magnifications. The only way to get more of the pen in focus is to take multiple pictures and composite the in-focus bits into one single picture.

Thanks guys! I just redid some measurements, and with the full 65mm of extension tubes I'm up to 10X magnification! That's a quarter the magnification of a biology dissecting scope
