Who here has had both of these lens and prefers the 16-45 over the 16-50?

Is the SDM and 1/2 stop worth the money for the DA*?

Is this has been asked before, please forgive me but indulge me anyway.

F2.8 is a full stop faster than F4

its all about where and what you are goint to shoot.

2.8 + weather resistant will allow you to use this lens almost everywhere indoor or outdoor, rain or sun, and so on

also 2.8 will give you better DOF for portraits.

16-45 is super sharp and a great lens for out door and its also cheaper and lighter

Yes. Especially as it is 1 full f-stop faster.

I stand corrected. Old minds sometimes get things wrong.

The silent focus is nice, but it's not much faster. Given the faster lens, autofocus should be slightly better in dimming light too.

The 16-50 is: 65% heavier than the 16-45 (600g vs 365g)
The 16-50 has: 9 aperture blades rather than 8
The 16-50 has: a really nice focusing ring (compared to a normal DA lens)

One aspect of the 16-50 which might be a disadvantage for you - it casts a shadow with the built in flash.

I'm really quite thrilled with the 16-50 and am glad that I bought it - I didn't actually buy it for f2.8, but instead for the weather sealing, and proper focusing ring. Having said that, I have some shots of family moments taken indoors I never would have been able to pull off with an f4 lens (without a flash), so I'm really glad that it goes to f2.8, even if I don't use it as such most of the time.

Yes, I started a little fire when I compared these two lenses (only in MTF data)...
DA* 16-50 vs DA 16-45 in IQ

My conclusion is a lens is a whole lot more than just MTF data - and the comparison of these two lenses exemplifies that. I much prefer the 16-50 despite what all the numbers say...

OrenMC just started a similar thread, there are some pictures to look at too

I posted there stating how unequivocally happy I am with the lens.
