New to me Sigma 100-400mm that I made an offer on eBay for, came pretty much like new in box with all documentation and accessories. The seller threw in a K&F UV filter, too.

I think I needed 400mm because while I like my 55-250mm, I felt like I could use more reach. My first impressions are this thing is a beast. Weighs in at 2.12 lb/1,251g, which is lighter than the Canon 100-400mm. Still, I wish I knew why Sigma didn't design/include a lens foot for it.

I'm thinking about buying Niceyrig cage, and using rods and a [lens support](https://www.niceyrig.com/products/niceyrig-universal-adjustable-height-long-lens-support), with the tripod quick-detach plate underneath the lens support for when using this lens, is that a good solution for supporting the weight while mounted on a tripod?

I forgot my gray card, so I didn't set a custom white balance for today, I used the Cloudy WB preset. Feedback welcome.

Photo #4: 400mm, f/6.3, 1/640, ISO 640, adjusted saturation, contrast, and brought down shadows

\*at the park today there were gnats flying all over, so I took my camera off the tripod and decided to keep moving. #2, #3, and #4 are offhand. This is my first hefty telephoto zoom lens and shooting offhand actually felt better than shooting off the tripod.
