The 135mm F/2 Defocus lens is a hard animal to tame. It does take great pictures, but focus is a struggle. I’ve found that it’s best to operate this lens manually, as the autofocus is slow and unprecise. However, it does lead some great photos, like this one of my compact SRAM Red crank.
The focal length also makes it a hard lens to use compared to a telephoto lens. However, the results are much better. Take a look at these shots that I took without much preparation of my bike. None of these photos were post-processed and you can see the nice defocus in the background. This means it’s the perfect lens for certain situation. I’ve also taken a few great portraits of my wife.
