Midrange Zoom Chapter 2



Big Leaf, originally uploaded by jjvornov.

After a morning at the dentist, I stopped by our best local camera store, Service Photo. I had a look through their used midrange zoom collection including all of the usual suspects. I ended up walking out with the Tamron 17-50mm f/2.8. It’s compact, fast and, in the non-HSM version I bought, very inexpensive compared to any other f/2.8 alternative.

It’s not a VR lens, but then I’m not so sure that I’ve gotten any real boost in sharpness in this focal range given that I hand hold relatively well down to 1/30th second.

Here’s one of the first session with the lens in one of my favorite spots for quck shots, a local 1 acre conservatory.

I'm an MD, PhD Neurologist who left a successful academic career on the Faculty of The Johns Hopkins Medical School to develop new treatments in Biotech and Pharma. I became fascinated with how people actually make decisions based on the science of decision theory and emerging understanding of how the brain works to make decisions. My passion now is this deep explanation of what has been the realm of philosophy, psychology and self help but is now understood as brain function. By understanding our brains, I believe we can become happier, more successful people.
