My Extreme Macro Test
Lens: M50 Camera: K7 
Posted By: Ouroboros, 07-29-2010, 04:52 AM

So after finally getting my mitts on a few sets of tubes... well, seven sets actually, I got down to some testing.

The first shot is one of the needle i used for the shot that follows it, as you can see, the mag I'm getting is crazy! After that is a shot of the pixels on my nokia phone and then its' a single green hundred and thousand.

As you can see in the last shot, which I took with my crap cell camera, the tubes look freakin silly.

I know the shots aren't great, they are the first I've taken with the new tubes and I wanted to throw em up here.

Are you serious? Wow! The resulting aperture must have been in the hundreds, if not thousands! The shot of the pixels is particularly impressive, as it clearly shows that the magnification is close to that of a microscope.

LOL, yeah the aperture must have been some ridiculous number, I had the aperture ring dialed at about 11 or 16 for the last shot which would have pushed the actual value well into 3 or 4 digits! Exposure times were VERY long, but the pixels are not so bad as they emit their own light

An online calculator puts the magnification at 7.5:1 Another member mentioned to me that 10:1 is officially in the Micro world, so yes things are very close to microscopic

These are just the first tests, and I have to get my rig sorted for this type of photography (as you can imagine, that lens need a lot of support!) I'll need to get myself a sweet LED light arrangement too. I'll get some better shots this weekend!

That's pretty unique...what does "a single green hundred and thousand" mean?, I still don't understand what's pictured there

About 9:1 magnification (?)... cool

My record thus far is a bit more than 10:1

100s&1000s I think you will find are uniquely an Australian name for them. I am not sure what they are called elsewhere, but it may help if I say it is the coloured sprinkles on Fairy Bread.
Does that help?

they are hollow tubes that make the distance from the glass of the lens and the sensor farther, allowing more magnification.

Great effort - I don't know why you just didn't try and reverse a 50 or 28mm lens on a 300mm lens? - you get a similar magnification with a far more useable rig!

I do like what you have done though - well done!
