Okay ...
Yes you can shed a few pounds...
Yes a crop sensor mirroless camera will give you bokeh IF you follow 3 simple rules
1. Focal length
2. Aperture
3. Proximity to subject and background
Very simply put...
If you can have @ least 2 of the 3 you can achieve the desired “bokeh” effect.
I have been shooting a fujifilm x series cameras for over 5 yrs. now and there is little if any IQ quality difference between finished images.
Yeah, this might require some retraining As good as reason as any to go play with a camera...
I know how to get the effect I want without a lot of trial and error. And where I want the bokeh effect, I tend to get close to the subject, to have a very short DoF.
