With backmarket it goes well. With the article I am very disappointed. Bought to use with a new SLR, the image quality is not up to scratch. I think it's only with the L series that you can expect good quality. I'm an amateur photographer with a lot of experience. I had some good equipment, especially the 100mm macro L series, but when I sent my SLR to the repairer, PHILIPPE OSELLO, he asked me to send the lens with the SLR because of a coupling issue. In fact, either he didn't know anything or he wanted to 'let off steam' because even the lens was rendered unusable before I filed for bankruptcy. I've lost everything. I'm having trouble finding equipment that meets my expectations.
