best Sigma/Tamron combo for Pentax K-5

Joel_Isaac · 06-27-2012, 02:17 PM

Hi guys,

After much consideration, I have finally decided to go with the Pentax K-5 over the D7000. I have decided to skip the kit lens and go with 2 Sigma/Tamron lenses within the 18-200 range. So far, these are the ones I picked.

1. Sigma 17-70mm f2.8-4.5 dc macro hsm / Tamron 28-75mm F2.8 AF XR Di LD Macro SP / Sigma 24-70mm F2.8 EX DG Macro

2.Tamron 70-200mm F2.8 Di LD Macro

As you can see, picking the 1st is the problem. Would really appreciate your opinion.

Thanks
Joe.

Of the three, I would go with the Tamron 28-75 because it has a very very good reputation on this forum. If not that, then the Sigma 24-70.

The Sigma 17-70 does not have the same IQ as the other two, but it is much wider.

You don't need to have every focal length covered. Maybe getting 16-50, 16-45 or 17-50 lens in not a bad idea. It is generally more useful than 28-75 where you are likely to miss the wide end.
I do own lenses of 24-90 and 28-70 range but in the end I prefer going out with DA* 16-50, because you can easily crop to get tighter FOV, but stitching images to get wider perspective is often a problem.

Also I strongly suggest to put at least one prime into the bag. You won't regret.

That is true, but it is still pretty good, and a handy focal length. I was always trying to back up with the 28-75, which I replaced with the older 17-70.

sigma 17-50 + sigma 70-200 or tarmon 17-50 + tarmon 70-200 or a mix with your favor

civiletti · 06-27-2012, 06:51 PM

I second liukaitc's recommendation.

From your original selection, can you live without the range from roughly 17 to 24/28? I personally don't often have a need for that range (holidays in cities and reportage being the exception), but that might be different for you.

NO way would I spend over $1000 on lenses and come away with nothing wide angle. 28-75 shouldn't be on the list unless you plan to spend even more to address that need. Perhaps even just the kit lens.

I've used the Tamron 28-75mm with the kit lens, and with the 16-45mm and with the DA15mm. All of those combinations work reasonably well. Right now, I'm using the Tamron with the DA15, which is a wonderful combination, but you gotta remember that 15mm is usually too wide for people photos, and you're better off using 28mm. Surprisingly, 28mm is wide enough for almost all people shots (its ideal actually), and some scenery shots. 28-75mm works fantastic for portraits.

When I owned the 16-45mm, I really liked the 16-45mm+28-75mm combo; both lenses are about the same size, but the 16-45mm is considerably lighter, and both give excellent results. I just like the DA15mm even more, because its the only compact ultra-wide DSLR lens made, and I've gotten some really wonderful shots with it. I'm considering adding the DA21 to the mix.

I would pair the beautifully sharp Tamy 70-200 f/2.8 up with a 24/28-70 f/2.8 if you can get a sigma 10-20 or pentax 12-24 to fit in, otherwise the tamy 17-50 f/2.8 is sharper than the twice-as-expensive pentax 16-50 f/2.8
