As is the deal with some guys around here, I am part photographer, part pixel-peeper, and part gearhead. This leads me to always wonder 'What's the best for ME?'
Don't mean to sound all selfish, but what I learned is to find what works for me, horses for courses, and all that.
More specifically, I have made a few bold decisions (for me) based on what I learned here.
1. I sold my much loved 17-40L and get the Tamron 17-50. I have things to complain, but the image quality and the extra $300 in my pocket is not all bad!
Special thanks to the following POTN member: watt100, LightRules, and Silverfox1.
2. I decided to remove protective filters off my lenses. I did some tests and I am led to believe that in MY case, the use of UV filter does degrade image quality to a noticeable level.
In conclusion: Know first what do YOU need and what do YOU want, you can ask specific questions, but remember to take everyone's post with a grain of salt. I hope this forum brings joy to all of you as much as it has brought me.
Thank you and respect to all of you.
