There has never been any attempt to bias my results, and, since my primary occupation is as a pastor, I do value honesty.
Just to be clear, I'm not in any way suggesting dishonesty or bias on your part. What I'm suggesting is that if you're testing lenses provided directly to you (as a reviewer) by the manufacturer, your results may be biased through no fault of your own, but due to the manufacturer hand picking and pre-testing the lenses you receive. Also, pre-production lenses, by definition, aren't representative of lenses that come from the established production line.
If you like the lens well enough to purchase your own copy, I trust you will update your review if the production lens you buy differs substantially from the preproduction lens Tamron sent you for testing.
Absolutely. I have ended up purchasing retail copies of several of the lenses that I have tested. I have also updated reviews both on my website and on threads here with comments about issues that I have encountered with lenses/equipment after review.
Even my contact in Tamron Canada is surprised at how quickly this lens is coming to market. They initially expected a longer roll-out period. I am somewhat skeptical that the copy I get my hands on will be a pre-production copy with the release date now not much more than a month away. I think that ship has sailed, and whoever shot these samples were using the pre-production units.
