Over the years I've accumulated a bunch of great glass and now find that I use four lenses the most.

They whole inventory includes:

75mm f4.5 Grandagon-N

90mm f4.5 Grandagon-N

110mm f5.6 Super Symmar XL

150mm f5.6 Sironar-N

210mm f5.6 Sironar-S

305mm f9 G-Claron

450 f12 Fujinon-C

The 450 gets used for 8x10 and the 110, 210 and 305 are also 8x10 able. I also get a kick out of using the 75 (when I remember to bring the bag bellows !!).

So, the question: does it make sense to sell the 90 and the 150 considering the other focal lengths I own ?? I shoot external architecture and a little landscape.

Sorry for the 'which lens question' ...

Thanks ....
