Need advice about lens...

[rysouke]

I am thinking of buying Sigma 18mm-250mm(latest with OS and HSM) and should I sell off my sigma 24mm-70mm f2.8... since i have a 10-20mm wide angle and 50mm f1.4mm....

depends on what you shoot.

I suggest actually knowing what advantages one lens will have over the other. The 18-250 is convenient, but has poorer sharpness between 24-70 than the dedicated lens, and has a smaller aperture.

Dont buy yet, rent. Dont sell first, pass on to those who may need it, then can ask back later hehe...

Better to compare the pic IQ first before planning ur next move
Lens w/ high zoom factor seldom had outstanding IQ

my advice to you -
1) dont just go for convenience and get one lens that covers the entire range 18-200. it can never be as sharp as having a prime lens at 24mm, 35mm, 50mm, 85mm, 135mm.
2) 18-200 covers a wide range but ask yourself how often is your most commonly shot range? it is probably just an assurance that you have the range covered but having a wide range doesn't mean you will use the entire range. i use 24-70 for almost everything. if i need to zoom, i can crop from my 24-70 with no loss of resolution.
