One our Bengal cats I had visit me in the home office this morning. Even with the blinds in the background it was a fairly low light shot. ISO 1250 F/2.2 Sigma 50mm 1.4
Have you spotted any American kingfisher? They are beautiful and highly skilled birds...One of the best wildlife photo venues in Texas (IMO) is Brazos Bend State Park, southwest of Houston. Lots of gators and aquatic birds.
