Originally posted by duotone66 Hi new to the forum,I switched from Nikon. If I could get some advice on lens purchases it would be great. I was thinking pentax 50-135,sigma 10-20 ex.and a 24-70 Pentax or ? I shoot outside in the PNW rainy dark I need fast focusing lens.Any help would be appreciated.
The choice depends wholly on your applications - and on Pentax lens line-up. There is currently nothing like a 24-70mm (except the one by Sigma). As other already noted: Pentax excells with prime lenses, though the new longer zoom lens (60-250/4) seems to be very nice, if you need to go that long.
If by 24-70 you meant the APS-C equivalent, the DA 16-50/2.8 would be the logical choice. A very nice lens.
