So as I held in my hands the unlimited possibilities that 10 frames per second offered, I knew I needed the glass to make that camera shine. So after a bit of research, I decided on the (old) very good 400mm f5.6 L. That lens was something else. Super sharp, easy to carry, light, and crazy quick autofocus.
No, it didn’t have image stabilization, but it was “L” glass - and man was it awesome. The 7Dmk2 was, indeed, the camera I had always dreamt of - great autofocus, pro build, super quick fps and it felt GREAT in the hands. Probably better than any camera I’d ever held before… maybe better than any I’ve ever held period.
With the 400 and a 1.6x crop factor, I was out at 640mm - not too bad, and with such great autofocus - I knew I was just days away from capturing an award winning shot.
Then I tried to take pictures as the light levels faded… Sure ISO100 was great on the 7Dmk2, but above about 1600, things got rough. Really rough. I had gotten so used to the D610’s low light performance and much larger sensor, that I was quick to be disappointed by the results.
Soon, I also became frustrated with the number of keepers I was getting with that 400mm lens. It had to be the lens right? It couldn’t possibly be my technique! So I scraped together some cash and bought the Tamron 150-600. After all, it was brand new - it had to be better than my 20 year old 400mm… AND it had stabilization.
Now on a 1.6x crop body I was out at a staggering 900+mm focal length equivalent. Yikes! What an amazing focal length for birds and wildlife. But man was it BIG and Heavy… so I started contemplating some options… because it sure is tiring to carry around that big ole lens and camera on long hikes…
