Sometimes if wanting to travel as light as possible with 4x5 I'll just take a 135 - but lately this FL is being supplanted with the 150 for this (single lens) use...as the 135 somehow seems a bit boring to me lately on 4x5.
As for 5x7...while I now go with a 110/150/210/305, with very occasional use of the 90, it is the 110 and 150 which I as of yet have not quite warmed up to completely for this format.
When I'd recently acquired the (optically wonderful) 110XL with the intention of using this to basically "replace" my 120mm F/8 Super Angulon, thinking that they'd be "close enough" in FL, I often find myself missing the very slightly longer 120. This preference might change over time and I may yet thoroughly embrace the 110, but for now, I'm hanging to that 120!
The other "jury is still out" FL for 5x7 is the 150. Often I think I'd be happier with something like a 165, but the modern options here are so few...with the 165 SA being a bit large and heavy, and the quality of the older WA Dagors being quite variable - also keeping in mind my tendency to print quite large (to 40x60 inches). At any rate, were I more in love with the 150 for use with 5x7, I'd possibly be wanting to sell my current 150 Apo Symmar L and looking for an Apo Sironar-W...mostly for its extra bit of coverage. Too bad that lens is getting really hard to find, and almost always really pricy.
