Ugh! What can I say? I shoot a Canon 7D MK 1 and have been using a Sigma 18-35mm ART lens with extension tubes for my close up/macro work. I bought this so I could avoid using the tubes due to the light loss. For the price it isnt a horrible lens, but there is noticeable grain even at ISO 100 and really good light. Nothing I cant fix in post processing, but now I traded time messing with extension tubes for more post-processing... I included several shots that have been edited in Lightroom. Nothing too crazy
