I’ll throw in my 0.02c here, which also mirrors a lot of other posts...
I have a bigma 150-500, 55-300, da*200, 28-105, 18-135.. (and many more of course)
But these are the relevant key group when planning a shoot out n about- if I’m driving I’ll take the sigma 15-500, as it’s big and heavy but has great image quality and reach
If I’m on foot, the 55-300, and the 28-105 tag along- light and versatile range for daylight (if I take a crop body, the 18-135 is surprisingly handy)
The da*200 can easily be put in the back pack for low light shots, as it’s small and compact for its quality, and is just so fun to use for the bokeh on wildlife..
A DA1.4x is always there, and works great on all above lenses, on a k-1, or a k-3, or k-p
(And often a nifty-fifty FA1.4 finds it’s way somehow into the bag... sneaky little thing it is..
)
