To those who advised me to shoot with fast zooms, thank you I already do that, check my signature and you will see the lenses I own.
"eal76" no need to be upset, the guys here simply were smiling because of a little typo mistake you made, just harmless fun, trust me I get laughed at too from time to time, all in good spirit
As I said I use 2 cameras and I thought of a set up of 135mm f2 on FX and 28mm f1.8 on APS-C
But I don't know how fast does the Nikon 135mm focuses, its really more of a portrait lens then general use lens
Or I could only buy a 135mm f2 and put it on the APS-C and use my 24-70mm on the FX., 135mm on DX body is equal to almost 210mm.
In the future I will definitely get another FX body like the D610 or maybe even D800 and on that a combination of 135mm n one and 28mm on the other sounds promising.
For times I need more flexibility like first kiss or anything I need to keep away from event I still have my fast zoom lenses which I don't plan on selling.
At the moment its just a thought and I find everyone's reply's very enlighten and helpful.
