Review on Sigma 135Mm Lens Canon 240954 by Iration Mccall

Using this large, heavy 135mm f/1.8 prime lens with a 90D crop sensor (@ 218mm effective focal length). Amazing clarity. Excellent build. Insanely shallow depth of field when you open it up. Ideal for photographing butterflies at f2.8 to f4. Definitely not an all round or versatile lens but if you have a dedicated application like environmental portraits and have enough room to work this lens is great!
