A few weeks ago, I blogged about a
modified Canon kit lens, in order to become a decent Macro lens. With a
second shoot, when I purchased a flash to enable better macro lighting, I was so pleased with the results, that I decided to try it again with a different lens.
I still had a
Tamron AF Asperical 28-80 f3.5-5.6 77D lens around that I tested before but did not want to keep. eBay would maybe have given me $10 or so, so better to have some fun.
First step was to remove the front element. That was fairly easy by peeling back the rubber on the barrel, and removing a few screws.
I then used a hammer and screw driver to knock out the glass from that front element.
To protect the inside of the lens against dirt, I recommend putting a clear filter on the front element. I had plenty around, so use a Skylight 1A filter.
And this is the result... looks like a normal lens, but is a macro monster. Do remember that you used to focus with the front element, so that capability is lost. You know focus by rocking your camera back and fort.
And a macro minster it really is. As you can see, depending on the zoom range, you can have a enlargement on a full frame sensor from around 1:2 all the way to almost 2:1, while keeping decent sharpness and focus depth. It is however a little less enlargement then I was getting from the Canon lens. But not bad for a lens I only paid $14 for. Not bad at all.
