replacement lens kit

Hello, I want to upgrade my lens kit (18-55; 50-200) with some F lenses...
Could you tell me what from the next lenses have a great IQ compared with the kit lenses:
F 35-70 f/3.5-4.5
F 28-80 f/3.5-4.5
F 35-135 f/3.5-4.5
F 70-210 f/4-5.6
F 80-200 f/4.7-5.6 ...

In other words, F 35-70 f/3.5-4.5, F 35-80 or F 28-80 f/3.5-4.5 has a greater IQ than 18-55 DA II?
And F 70-210 f/4-5.6 or F 80-200 f/4.7-5.6 compared with 50-200?
do you ever compare F70-210 with DA 55-300 in IQ terms?
Thank you,

I like the FA 28-70 f4's output better than the kit lens... BUT the front barrel rotates during focusing and the build quality is a bit iffy and loose compared to the newer DA.

Do you really want to give up so much at the wide end? You lose a lot going from 18mm to 28mm or 35mm.

If you look on this site's Lens Review Database, some of those lenses are not highly regarded at all.

I would also suggest that the most practical replacements of the kit lens are the DA 16-45 f/4 or DA 17-70 f/4. The 17-70 is a reasonable budget choice that has good image quality and decent build. There is also the option of going non-OEM, like the Sigma 17-70 or Sigma 18-50 f/2.8. Anything better and you're looking at the Tamron 17-50 or Pentax DA 16-50.

Then for telephoto, the most obvious choice in my mind is the DA 55-300, which is the best in its class.

thank you for your replies, but I could find some F lens really cheap, so I need to know if somebody test for example F 70-210mm vs. DA 50-200mm/50-300mm.
And from F lenses which one is best for macro? (vs. M 50mm with reversing ring)?
Regards, Edi

I cannot speak from personal experience, but the F 35-70 is highly regarded.
