My second lens

...and last one for a while.

Currently my only lens is the Tamron 18-250, f3.5-6.3. A very nice zoom range and good image quality for what it is, but not the fastest lens.

So, I'd like my second lens to be a fast wide to close tele zoom.
My choices:
1. Sigma 17-70. Perfect zoom range but not a constant aperature and I fear not fast enough in the 50-70mm range. Almost universally accepted as a very nice lens.
2. Sigma 18-50 EX Macro. Not as nice a zoom range as above but a constant f2.8 and this is where I'm lacking with the 18-250. Again, almost universally good reviews.
3. Tamron 17-50. A little wider than the sigma and has the constant f2.8. However, not widely reviewed yet and the few comments I've seen leave some questions.

So, I'm really leaning towards the Sigma 18-50. I know it will be a good choice but am I leaving any lenses out that I shouild be considering? Are there any affordable zooms that open up bigger than f2.8? I'm not interested in a prime.

Why not a prime as second lens??
A nice bargain like the Fa 50mm 1.4 or a more expensive but worth FA 43mm 1.9.
That would be my choice in your shoes.

Best,

Unfortunately, a zoom with a bigger aperture than 2.8 doesn't exist nor would it be affordable. From your post, I assume that most of your shootings are done at this range. Sadly, most fast zooms at this range have either BF or FF issue. I would either rent or go to the store to test them out. Handling is also important beside IQ, so you should test all of them out before you get anything.

Olympus has two f2 zooms, they do exist but they aren't particularly affordable

My bad. . I guess they do need that extra stop for the heavy weight and money.

That, and with the 4/3rds sensor, F2 allows the depth of field of F2.8 which is nice for portraits.
