50mm & Kenko Extension Tubes Test Shots

My wonderful girlfriend answered all my birthday wishes today by buying me a 50mm 1.8 and Kenko Extension Tubes. I have been after them for a while now and have done all the internet searches to glean as much knowledge as I could.

The 1 thing I couldn't find was some test shots to have a look at so that I could see what the effects of the tubes were. So thats what I have done.

I am not sure if what I have done has any relevance, but it has given me a rough idea what the effects of the tubes are.

For those looking into getting these tubes, I cannot recommend them enough. Some people have made note of the build quality but I have to say that the ones I have seem extremely sturdy.

These shots are of a 0.5cm power symbol on the laptop. Shot at the same shutter speed (1/80) so they might not be crystal clear but the aim was to see how close I could get and what greater magnification that resulted in.

Pictures are: 0 extension, 12mm ext, 20mm etx, 36mm ext, 48mm ext, 56mm ext and 68mm ext. All shot using a Nikon 50mm 1.8 at 1/80 ISO 200.

That was damn annoying. Shows the last time I posted anything. I supose it serves me right for:

a. Being cheap and not buying picture hosting space
b. Not posting enough pictures to warrant buying the above!

so extension tubes allow you to use astandard lens and minimize the minimum focal distance?

Both my tubes and 50mm were from a seller on eBay. Incidentally the cheapest for both items on the whole site (Buy It Now)! If anyone would like to know the name let me know.
