Tamron 28-75 (2.8) or 17-50 (2.8)

i already have a "travel lens" (18-250) but I am looking for a faster 2.8 that would act as a 'defaut' lens.

I am undecided between ranges of the Tamron's 28-75 (2.8) or 17-50 (2.8)

Initially, i was keen on the 17-50 but a very talented friend of mine told me he uses the 28-75 on his nikon and finds it to be the first option when going out to shoot.

Suggestions?

Depends on what you like to shoot. I have both and I somehow prefer 28-75mm for for kind of photography I do (street photography and portraits). If you like to shoot landscape and architecture, 17-50 would be better.

agreed, i tend to shoot more tele so i use a 24-70 sigma. If you find yourself at the wide end more than at the tele end, go for the 17-50, otherwise, go for the 28-70. They're both amazing lenses so im sure you'll be happy with either choice

I was in the same postion as you. Except that I also considered the pentax 16-50 and the newest sigma 17-50 [but the former has possible sdm issues, the latter is a big lens] I finally wound up with the 28-75:
-I already had a travel lens sigma 18-200 that was ok at the wide end.
-28-75 gets better rating than the 17-50
-I do like taking informal portraits and the longer end is better for this.

The tamron lenses don't look very nice and are rather loud. But the image quality is good.

Having said that, after graduating from the 18-200, I can no longer use it. Having gotten used to better and faster lenses I don't carry it anymore. I have given it to my kids to practice with.

I would personally go for the 28-75 because it makes a wonderful normal - portrait zoom, and it's better in low light.

BUT I have wide angles covered with my DA 15, so I'm a little biased, aren't I? It totally depends on your subjects. 17-50 for environments and things, 28-75 for people.

i would suggest you consider both. the 17-50mm for short tele and the 28-75 scales up to a 42-112mm lens. you would have everthying covered from wide to long tele.

Way too much overlap. I suspect you're confused about how the "crop factor" works. The 28-75 only "scales up to a 42-112" if you are comparing to how things would look on a FF/film camera, but the OP has given no indication they own such a camera, so the conversion in probably meaningless. And if you're going to "scale up" that lens, you have to scale up the 17-50 too. Crop factors don't affect only some some lenses: they affect *all* lenses. But again, only if you're already accustomed to film.

I have them both. I wouldn't hesitate to consider throwing either one in the bag to supplement the 18-250 (I have that as well). The 28-75 lived on my camera for over 5 years and I never had a complaint, unless I was indoors when I used my Pentax 18-35. The 17-50 replaced that (I killed it in a motorcycle crash) as my fast wide lens.

It all depends on what you're going to shoot- do you need the reach of 75mm or the width of 17mm when the 18-250 isn't on the camera?

When I'm around home the 28-75 is more versatile for me, as I live where there are lots of wide open spaces. When I hit the big city, the 17-50 usually gets the nod. Honestly, I can't tell by viewing the pics on my computer which lens took which pic without viewing the exif info. I almost never take both lenses out at the same time.

The 17-50 may be marginally sharper, but some days the 28-75 wins. Probably more to do with the shooter than the inherent differences between the lenses.

And finally- if you plan to shoot film, get the 28-75, as it is designed for that & the 17-50 isn't. Pick the one that best fits your needs and don't look back. Enjoy!

thanks!!

thanks all for the responses.

I like shooting wide but I remember the old kit lenses on my k10 were annoying me every time i hit 55.

So i may start w/ 28-75 w/ the presumption that i can always pop in the travel lens to get the 18...

and then eventually get the 17-50 ...or better yet, a super wide just for landscape.

thanks again guys and gals!

Or as Marc pointed out in another thread, the Pentax 15mm ltd would make a wonderful (and compact) sidekick to the 28-75mm.
