Tamron SP Adaptall-2 90mm f2.8 72BB Mini Review

Like the 52BB, this lens is a true macro lens, except I can go all the way down to 1:1 image magnification. It is a tad slower at f2.8 instead of f2.5 and it is all plastic material, making this lens much lighter. It's not as classy looking as the 52BB and is harder to find. However, this lens is the true grandfather of the current Tamron 90mm f2.8 macro lens which is more than twice the price. 

My subject of the day, my daughter's Lego friends!
