Two of the lens I currently own are the 24mm f/2.8 and 200mm f/2.8L I have been thinking about 24mm f/1.4L and 135mm f/2.0L and possibly compartmentalizing things with 300 f/2.8 or new Sigma 120-300mm f/2.8. In other words separating my kit a bit depending on what I am doing that day. I would appreciate some feedback on 24mm f/1.4L and 135mm f/2.0L from users with hands on. Most of the work I sell is covered in the 24-135mm range so the additional cost is justifiable. But, I would like to dabble in wildlife a bit. I live in the Fl, Keys. My back yard is the Florida Everglades and in my front yard are the reef and the Caribbean. Please understand that a great deal of our birds are 4 and 5 feet tall. So 300mm f/2.8 and TCs are probably more than adequate. They are not to shy if you leave your door open they will walk into your house.
