18-135 or new 55-300 PLM as an WR upgrade for old DA 55-300 - HELP :)

I feel the need to change my old DA 55-300 to something newer and better. I just can figure out what should I buy.. ;/
I have K-70 with Sigma 17-50 and DA 55-300 and I want to keep the sigma as IQ is superb and I use it for landscapes and architecture, and night shots.

I use 55-300 for kids shots, parties, animal/bird shots mostly. All of those are usually moving fast and unpredictable + amount of light varies a lot

What I need:
- single WR lens that I could go around in bad weather or bad conditions or winter etc.. when I can't take the Sigma
- basic lens that would always be with me
- lens with longer focal to shoot kids/people that are a little farther than the 17-50 reaches

I wanted 18-135 mainly due to fast AF a lot of people praises, but I read that new 55-300 PLM also has fast and good AF, and at around 100-150mm it is even sharper than 135 on the long end.

Anyone got both lens and can compare the AF speed and IQ?

I considered both and can't decide which one is better, some + and - below:
+ 18-135 wider at short end
+ 18-135 better for everyday carrying
+ 55-300 longer
- 55-300 darker
+ 55-300 i am used to those focal lenghts available
- I want to get a little more into street photography so I might not need the 150mm+ very often
+ I want 300mm for bird shots
+ 150-300mm focals might be usefull for kids shots (I have a knee condition that prevents me from running)

I considered also the 18-135mm + some long bird lens but I did not find any good long lens (might be manual) that does not cost a small car..

Anyone HELP? Anyone have had same dilema? or know other solution?

I own the DA55-300mm(no WR) and the 18-135mm....and next lens I buy is the newest 55/300 plm....

The 18-135 is good but if you add a K1, its only usable in crop mode....square crop isn't bad, the vignetting is a lot less than FF mode.

All reports on the PLM are positive, its compact and focus is miles ahead of screw DA is mainly used at the long end with a 1.4TC, so with less light than the PLM.......55/300 is a great focal range for MY walk around...many will disagree for their walk around.

I only shot birds if theres no surfers!

I picked the 16-85 since WR is important to me. Wider and long than Sigma, but slower...
How often do you need WR when shooting at kids and birds? If not too often, I would suggest 18-135.

The 18-135 and the 55-300 are completely different and suitable for different purposes. You have the wide end covered with the Sigma and the 18-135 will add little to that that the 55-300 wouldn't also cover.

Since you already have the Sigma, I'd go for the new 55-300mm. Maybe you can add the 18-135mm later if you need a single all in one lens

In addition the 55-300PLM is a bit faster from 70 upwards. Have a look here. I listed the open aperture changes.
