I rem that he can play any instruments. Self taught all the way since young.
Even can play electric guitar behind his back blindfolded.
Photography is just like music. It's an art. You need some talent to start photography.
If got no talent, means got no talent. Give u a FF, also no use. No good photos will come out.
In other words, a real talented photographer should be able to shoot good photos with any brand and any model.
Be careful of those who say "I only use brand xxxxx. The rest are no good and I don't feel comfortable with them."
