What lens to purchase?

1. 10-24

Larger lens, having 10mm wide and OIS is great.  A little soft in the corners, not as good as the 23/1.4.  But, it is a wide angle zoom --- corner sharpness is usually forgiveable for most shots.  I bought the 10-24 over the 14 because I don't shoot ultra wide that often, but, when I do, the 10-24 meets my needs better -- especially having OIS for hand hold shots over head or down low.

2. 14

Great optics in a small package.  However, it is also slower.  If I was putting together a very small prime, package I'd probably for for the 14.

3. 16

With WR and f/1.4, the 16mm looks to be an excellent, fast wide angle lens.  End game prime that probably won't be replaced soon.

4. sell 18-55/27 and buy 16-55

The 16-55 is big and heavy and doesn't have OIS.  If you plan on using the 16-55 a lot as your main walk around lens, this makes plenty of sense.

5. sell 18-55/27/90/55-200 and buy 16-55 plus 50-140, remaining 35 1.4 for its magic lens

If you are mainly a zoom shooter, this really works.  You can then buy a 10-24 or 16mm for the wide end as you see fit.

6. i do not need other lenses

#6 is not the answer --- there would be nothing to discuss if it was, therefore it isn't.  

If it was up to me, I'd get the 10-24 or swap the 18-55/27 for the 16-55.  16mm is a lot for wide angle prime that I wouldn't use its advantages that much; 14mm is getting to be a bit dated (i.e., rumors of it being replaced next year are starting).

The 50-140 is very expensive and heavy.  When taking portraits, I prefer the 90 over the 50-140; hence I couldn't see selling it.
