macros,
ok I don't own a macro lens, but I read something about reversing a lens. The basic idea is to magnify an object so its 1:1 or bigger with your frame.

Lets look what are the requirements to reverse a lens:

- tape to connect lenses -> have some
- a prime -> have a 50mm prime
- a second prime or a zoom -> have a couple of zooms

the zoom I used is my "el cheap o" 50$ zoom, cause it was the only one which diameter somehow fits the diameter of the 50mm. I put a cheap UV Filter in front. to avoid scratching it. I tried my 300mm zoom which would give me a magnification of 6x, but could'nt get anything in focus.

So I had a mini macro with a magnification of: 1.6 (80mm/50mm = 1.6) Which should be a start. For the lighting is used one SB-600 which was not much help, cause m working distance was arround an inch. As macro table I used the 70-300mm lens, cause I could raise and lower it using the zoom/focus ring.
All pictures are right out of the camera with no adjustements.

conclusion
as we can see none of the pictures are per


this evening lindsay got all exited, cause she found a book, which includes an article olfiver,martin and I wrote a while ago.

You can find the book here. If you want to read the article, you can download it here for free.

The picture is lindsay looking at me annoyd and telling me enough pictures for today...

I really like the performance of this lens at 1.8 its so sharp, I always need to unsharpen and optimize the picture in post processing.

I also think I'm addicted to fast glass now and looked already for prices of used lenses like,

80-200mm F2.8 nikon
300m F4 nikon
90m F2.8 Tamerom Macro

And prob. will buy the macro soon, cause I have 280$ credit at adorama. Reason is that I returned a lens, which I did'nt like. ( 200-400mm Tamerom, very bad CA over the hole range, but quite sharp. We could read the registration number of planes on the airport 2 miles away!)
