I'm throwing this out for discussion because I still meet the occasional photographer who thinks that if one isn't using Nikon glass on their Nikon bodies, then one is using garbage.
If I'm talking about you, then I'm going to apologize in advance, because I couldn't disagree more strongly. Like many others, I got into photography because of interest. If I never make a dime from it, I'm still happy. Third party glass gives me an affordable way to pursue this wonderful hobby without a full-on mutiny from Angela.
Now for the article.
I kept reading, to see what third party glass he was using. It was only near the very end when I realized that he had been talking about Nikon glass throughout. Then he decided to solve his focus issue by replacing a $1,799 lens with a $8,999 lens (Nikon Canada current prices).
Would this be a good time, to point out that one can buy a fully equipped sailboat for less? I don't think that this solution would be available for many photographers.
While I don't dispute the quality of Nikon glass, I do think that Nikon's pricing is the best thing that ever happened to Sigma and Tamron. We've talked about Nikon's pricing for camera bodies. I think the same holds true for glass.
