The lightest kit I have found is an MX with 3 M-lenses: 20/4, 40/2.8, 85/2. From there you can add, on the optical side:
An achromatic close-up lens #1 from Minolta (it takes the 40/2.8 from its min. focus distance to about half of it). I have to see if it gives better results on the 85mm A 1.4X-S converter to get a 120/2.8 or a 2X to get a 170/4 (not the first K6-2X which is designed for 135mm to 300mm lenses) A polarizer and a "universal" YG filter Then, some "extensions": A tiny pocket Minolta "20" flash (20 GN with 2AA) (I can also change the MX for an LX and bring a 200T flash with cord for off-camera TTL.) A Cullmann 2101 (a very light mid-size tripod that is for MX + small lens) A lens pen, a small note book, a level for water photos with the 20mm. This is a kit that permits only occasionnal macros (or rather "close-ups"). If taking macro is important, I'd build something around the 100/4 or the 50/2.8. I have been thinking about the bellows lens on a light bellows to go to 1:1 without tubes. Not tried yet. As you see, I'm an old timer who likes to focus by eye...
