Nothing to be sorry about. My two main shooting modes are M or Av. To be honest, I can't remember the last time I shot in Auto, apart of just testing how the camera will behave in certain conditions.
In my travel to Egypt, I often found myself shooting at low shuter speeds, resulting in trepidation and unusable photos. I'm very reticent of user ISO values above 100; I would even say I'm a purist of 100 ISO, and that I do what I can to don't gove above that. I'm starting to think that might be the problem, and that I should be starting to shot without fear at 400 and even at 800 ISO, giving me two or three more shutter steps in comparison.
Thanks a lot to taurus9. Those field test are great, and they do really show the difference between two lenses. Nothing more "scientific" is needed. They really do the work.
I'm starting to be in GeneV's side. I've been in photography for around 10 years already, not proffesionally, but on a high amateur level. I do really care for image quality and technical superiority, and I do recon that the Tamron is superior to the Pentax kit, but these differences will only be seen in big prints or by very critical eyes. It's although undeniable the fact that the Tamron is a faster lens, constant f2.8 , and because of that I will still consider it as a worth buy, giving the fact that the K10D is not specially good at ISO speeds, and that I find that being my most common problem. I'm still thinking about it.
Regarding the technique, I don't fully understand your advice around that. What do you mean by improving my technique? I do understand the principles behing the relations between ISO, Shutter and Focal. How to use and select them. I don't know much about AF techniques though. Is it something I should be taking care of ?
Well, thanks a lot for your opinions. This is being a great threat for me.
