i realise f2.8 is good on my 60D crop, but my m43 GX1 need f1.8 below for subject/bkgd isolation, if this new 12-35 f2.8 is gonna be >1000bucks, i rather have 12mm,20mm and 45mm prime and 14-45 variable aperture to complete my lens lineup.....
There are two ways to see good subject/background separation. One is the amount of blur and the other is the quality of the separation.
No doubt the dof will be thinner on the 3 lens u mentioned. The 25/1.4 is even sweeter than all 3.
Not defending this lens, but I am skeptical after their 45-175 and 14-42 booboo. The selling point of this lens is the weather sealing, constant aperture zoom plus near prime quality, just like what the 43 offerings are. would not buy this lens until more reviews.
Having said these, I will still keep my 20/1.7, 25/1.4 and 45/1.8. Why? 20/1.7 is really a nice lens for food photography on close up. 25/1.4 for portrait and 45/1.8 for that reach. Of course all 3 gives the low light capability over the Trinity zooms.
Imagine, 7-14@300g, 12-35@305g, 35-100@550g, 100-300@520g, FL600R@270g and E-M5@450g. Less than 2.5kg and we can travel around the world from 7-300mm (14-600mm against 135 system).
Of course we can use light stuff like FE, 12/2.0, 20/1.7, 45/1.8, and 45-200.
