| I think what you'll notice most is a different rendition of colours, followed by some increase in sharpness. Going from a kit lens to the 16-50 is really a blow away for the most part. The feel from photos I've taken with the 16-50 is more film like to me. The kit lens renders photos in a way I've actually come to like (since selling it), and there are some instances where the feel is quite pleasing - and there would be the odd moment where the kit lens *might* be preferred. Like a scene where you want hard transition of colour gradients and less micro contrast. But overall if you get a good 16-50 there would be no going back.
Couldnt tell you what improvement you should expect with the 50-135 except to say Im loving mine after the initial front focus adjustments and measurements phase. In real use in a camping trip recently the results were up to scratch. Very sharp lens, to the point where it's difficult to tell you are looking at 100% crops most of the time.
A side note with the 16-50... Personally I think its made my photos worse, Im now lazy with composition. I just point and shoot and see a great rendition of colour and sharpness with a more film like quality, gawk at what the lens can do and move on. I've taken better photos with the kit lens thus far. I think Im still in the *awe* phase of the 16-50 despite it being with me for a while now, I'm sure itll change eventually. |
