The 85/3.5 works fine on the FT1, although as an effective 229mm lens it works best on a tripod rather than hand held. Here's mine on a J5 via the FT1. I've also got a Really Right Stuff bracket attached so I can use my tripods fitted with the A-S clamps. Normally that's way too much focal length for the J5, but mounted on a tripod I can swing the LCD out horizontal and work from above to say my knees.

Remember that
focal length is focal length independent of format (CX, DX, FX). If you have an FX lens that gives you 1:1 it will also give you 1:1 mounted on a DX or CX body. It just seems like it is giving more magnification because you are seeing the smaller area of the small sensor just as you get by cropping the FX image.
I'm not sure which 70-300 you are talking about here. There are definitely people here who use the CX 70-300 on a V3, including me. But I can't speak to the DX 70-300 as I've not paid close attention to the bodies users have mentioned.
As far as processing goes I and other shoot raw, while the are others who work directly in jpeg. I too use Deep Prime for noise reduction as I couldn't ignore the others in the old N1 forum who recommended it. Now I can't imagine using an N1 camera without having Deep Prime in my work flow. As far as sharpening goes I seldom see a need to add extra sharpening but do occasionally use Smart Sharpen in photoshop or ON1 NoNoise with the NR sliders set to zero.
Yes, the older 300/4D is large and heavy compared to native N1 lenses. That's why I traded up to the 300/4E to get a smaller and lighter version. At 26.6 ounces it is 7 ounces heavier than the CX 70-300 (19.4 ounces). I'm willing to accept that 7 extra ounces for the f/4 aperture, but for the usual walkabout birding the CX 70-300 is a better way to go.
Me too. The 85/3.5 needs a tripod for best use. I don't like to go beyond the 10-30 or the 32/1.2 for normal use on a J5.
I've tried the DX 35/1.8 on my N1 cameras but couldn't see the point given that I've got a CX 32/1.2.

The 40/2.8 makes more sense to me.

I don't have any idea of how you can get a fast wide lens for the N1 cameras by adapting a larger format lens. 17mm with the 2.7x factor makes it act like a 46mm so it does nothing that the CX 10/2.8 already does.
