I am going to make an investment for recreational purposes into a Canon 30d from my old Canon Elan II. I plan to buy the camera body, and 430ex flash to double my rebate dollars. I also will keep my Canon 50mm f1.8 lense.
I will use this camera for just about everything, portrait work with my kids, local sporting events, beach shots, family vacations, and everthing else. I like to take shots and blur the background to make the subject jump out.
I am trying to decide between the Tamron 17-50 f2.8 and the Tamron 28-75 f2.8 lense as my "standard" lense. Considering the 1.6x factor, these lenses are equilvalent to 27-80 and 45-120 respectively. I was considering the Canon 70-200 f4 L as an additional lense purchase (equivalent to 112-320).
If I go with the Tamron 17-50 and the Canon 70-200 f4 L lense I will have an effective gap between 75 and 112.....and if I go with the Tamron 28-75 I will overlap on the long side but my widest will only be an effective 45mm....18mm short of the effective size of the Tamron 17-50. Also, if I ever go to full image sensor the Tamron 17-50 will be useless.
What do you think is the best match? Any other suggestions, combinations??
