Tamron 90mm F2.8 - 1:1 macro

Hand held (lucky shot) 1/200 - F4.5 - ISO 200

Cool - always heard good things about the Tamron 90, altho never used one.

When I took that shot the focus motor was constantly making minute adjustments on account of camera shake.  Looks like my tripod come in handy after all.

Yep, becomes essential at high magnification. I have done close to 1-1 handheld but only with elbow/arm/camera braced on a rock or something. Let's see more

So the ring light finally arrived.  Truth be told it didn't come with an adapter to fit
the Sigma 17-70 macro and that led to the Tamron 90 macro.  In other words... a
cheap light made in China seemed like a reasonable excuse to buy another lens. 

Here it is mounted on the camera. 



Note the famous big power amp on the left.

The control module is powered b 2 AA batteries and also comes with a 3 volt DC
adapter and it does fit onto the hot shoe, but I have it sitting on the floor.   




The two images above were done with a Cool Pix lest there be any confusion.
The images below with a Pentax K-x - manual focus mainly at F2.8.




There seems to be a fair bit of CA in some of these images, especially on the dime and around the queen
further down .  Not sure why that is?















Again, these are all manually focused.  I was thinking about getting a Katzeye, but I'm not so sure I need
one...  The light has 48 LEDs, but can be switched to run only 24 either on the left or the right.

I should hasten that the 'halo' especially in the 5 cent piece is the cap
from a bottle of Tea Tree oil that I used as a riser.

For convenience hand held sure beats setting up the tripod, but the result isn't quite a sharp.
