A new lens for me. Sigma 70-200 f2.8 OS..

very simple - that was the answer to the bokeh question - and I am not talking about the image quality here.

It was mentioned that a f/2.8 zoom is better then a f/4.0 zoom (which is obvious btw) and then I brought in the 135 f72.0 which has again better bokeh - far better to be presice

I've treid to explain how I see the whole zoom-thing in brief words.

1. When I travel lean - I want to have the least possible weight while maintaining the utmost image quality that's possible - or in a crowded place where I can only carry one lens
2. When I am not traveling lean I have the option to use whatever suits best for the task

Everyone might come to a different conclusion. Convenience is not my aim - thus zoom or primes is a question that does not raise for me.
Let's think for a moment hat all you'll ever need from a zoom is the lower and upper end of the focal length - what about owning two DSLRs - one with the long and one with the short end - I've seen that at official events from PROs a lot - and I do it the same way.
If I really want the utmost bokeh a f/2.8 zoom might not be good enough knowing the quality of the 135 f/2.0 - but if I want to travel lean a f/4.0 zoom might be just good enough - not being much worse compare to a f/2.8 zoom - in other words good enough but significantly lighter.
Out of the box thinking
I see rather seldom a Pro with only a zoom on the camera for formula 1 - they all carry multiple cameras with dedicated lenses for the job - that's what I do too

Image was captured from the McLaren VIP lounge at the last Nuerburgring formula 1 race - btw I rather seldom see 3rd party lenses even though they are significantly cheaper
