Re: Interchangeable Lens Ranges
It can be confusing, there is a lot of overlap and sometimes compromises are necessary.
Probably my favourite lens is my Sony 100-400 GM, but certainly most competitors have virtually identical offerings.
Probably my most used lens is my Sony 24-240 super-zoom which is a bit bulky and probably not Sony's best optical quality but for travelling fabulously useful. Compromise is it's a bit bulky so travelling round areas where you really don't want to show wealth just like a big arrow "target". Often a Shemagh makes it a lot less obvious or carrying with wrist strap rather than round neck. You need to consider many different aspects.
nb most lens focal lengths are for full frame sensors. Use them with an APS-C sensor and the focal lengths will be x1.5 times longer (1.6 for Canon) due to the smaller sensor.
