2010 but It'll give you the idea...

I require the 16-50 and the 60-250 DA*.
Sudden rush of blood and I need to scratch this itch! Due to the type of Phtotography I'm getting into the above two Lenses would be the most useful for me, and yes I just want the 60-250!
I reckon they are comparable in Used value so is there anyone wanting to go Prime???
My Quartet are lovely and will be missed, only the Lens Caps have any Marks.
Will post pics if required when time allows...

Big fan of the 10, not too big not too small.
If it looks right it is right.

Let me know how you get on Stefan because I may be travelling down the same road soon, with the bag and similar Lenses...

I'm with you there Stefan!The ten looks good but if you can sort out the position for everything the 5 is the ideal size for a small kit, I have my eye on it too for my K5 with just the DA Ltd's, basically so I can have my Camera with me all the time.

Good look at a 20 here Stefan...

30's definately too big for a light walkaround kit I think1 The temptation will be to fill it and then the comfort angle just goes out of the window,you'd end up carrying two bodies Stefan, Well at least I know I would! You are corrrect that the 20 is only deeper height wise, since the bags expand a bit IE they are soft could you not turn the K5 90%? the width of a K5 Can't be any more than a 1DS, that way it could just go to the bottom of the bag? Am I being daft here?

On the right of that pic above is a 70-200 AFSVR, I think your'e gear would fit but if your'e not sure maybe the 20 would be better?
That said a D300 is a lot bigger than a K5.
Flash on the other side and the 50-135 on the left...?

Without being taken the wrong way you have 9.5" to play with there!
And it folds up too
It gets worse I'm off:arrow:

Thats close to my my current fave Stefan I don't own it however, I like the Retrospective 10, I would think it big enough?

I think the 20 is a bit square looking and there would be a lot of space left at the top of the bag?
10: ID: 12” W x 9.5” H x 6” D
20: ID: 12” W x 11.75” H x 6” D

Your 50-135 is only about half that...
