2020 Midrange Shootout! 24-70 GM vs Sigma 24-70 DN vs Sony 24-105 vs Tamron 28-75 vs Nikon 24-70 Z

All shot on an A7r IV except for Nikon 24-70Z shot on a Z7. Focused at center at f/2.8 for each focal length. Tripod, 2-second timer delay, electronic shutter, IS off. ISO 200, Shutter speeds of 1/4000 (f/2.8) to 1/500 (f/8). Shot raw and processed in LR with all defaults except sharpening set to 45/0.7/35. Composite comparisons show center, midrange, and extreme right edge, all 100% crops. Sunny day with light filtered through thin high clouds, sun behind me, light intensity changed slightly between lenses.

All lenses are reasonably well centered except for the Sigma, which exhibits significant tilting at 50mm at all apertures (full-sized 50mm f/2.8 image - left side soft) - also tilted at 70mm but less so. Messed up the framing on the Tamron, so it shows a slightly shifted portion of the scene vs the other lenses compared.

Composite Comparison: 24mm
Composite Comparison: 28-30mm
Composite Comparison: 35mm
Composite Comparison: 50mm
Composite Comparison: 70mm
