It transpired that somebody bought a 75-300 lens and a wide-angle converter with their camera. Now the 75-300 isn't the best for sharpness but it's adequate. When stopped down to f8, it's about as good as most other lenses. The silly billy then posted about it on a digital camera board instead of trying to work out how to get the best out of it.
I am rather glad that I'm not a member of any forums any more. I had to deal with assinine answers to practical questions. I need not have bothered because invariably after digging around I found every answer and more than I needed. All I had from forums was aggravation.
So, this is another typical day in the useless world of DPReview. Just for a laugh, I looked at some of the "reviews" of camera gear. Most read like sales brochures and the "test" photography was extremely uninspiring and unchallenging. Needless to say, the next question is - who owns DPReview? It seems pretty much to be an Amazon venture.
Interesting - a formerly independent camera review website owned by a camera retailler. How unbiassed is that likely to be? From the reviews, extremely biassed. From the "discussions" just a load of pillocks posting for the sake of posting.
My recommendation - give forums a miss as well as camera review sites.
