Sigma 28-70/2.8 EX FG or Sigma 17-70/2.8-4.5 DC Macro ?

Hi everyone!

I am a quite new in DSRL photography and I need your advices.

Recently I bought K10D body. The seller gave me an opportunity to try Sigma 28-70/2.8 2 weeks and if I like it, I could purchase it for about 180 EUR/263 USD (I live in Bulgaria, Europe).

The price here for new Sigma 17-70/2.8-4.5 is 332 ЕUR/489 USD.

I like to make human portraits - kids, adults; shooting nature scenes; macro sometimes....
May be 17-70 is the better choice, but 28-70 comes with good price and it is very helpful in low-light scenes and indoor portraits.

Shall you comment what would be the proper choice for me, considering the two lens' characteristics, the prices and my shooting-object preferences.

Thank you!

you might also want to look at the tamron 28-75 f2.8

the ultimate decision is how you intend to approach the wider angle , but you would probably be happier with a constant F2.8 lens as opposed to the slower 17-70 lens.

I assume that you still have the kit lens to cover the wide angle, and unless you are looking for a single lens solution, the constant apature lenses are a better option

In fact, I don't have kit lens, I bought only the body.
Tamron is a little bit more expensive here...

So, I should deside what is more important to me - to cover the wide angle, if I will shoot landscapes, or to prefer the constant light 2.8 aparture - to have more opportunities shooting in low light conditions and indoor...

Thank you very much, Lowell Goudge.

Anyone who owns 28-70 to share his opinion?

The 17-70 is a far more useful range. And indoors, when you may generally use the wider setting, it will be near 2.8 or 3.5.

28-70 just is not wide enough for lanscapes particularly. If you plan on getting a 12-24mm or 14mm or other ultra wide in the future, then perhaps the 28-70 would work for you.

The 17-70's also significantly smaller, and since it's sharpish wide open (the 28-70 isn't really until f4) the speed difference matters less.

Just picked up a 17-70 today, and I'm impressed with the little thing.

Get the 28-70 f/2.8. It's a great lens and for the price it was offered to you it's a great price. I have it and I'm very happy with it. If I need something wide, I use the kit lens, but so far 28mm are as wide as I'd like to shoot.

I use a 28mm prime for 99.9% of my landscapes

Thank you, guys, for the comments!

Hmm, the votes are 1:1 for the both lens...

I really like the constant f2.8... And I really use it most of the time indoors for portraits - especially in this winter time, when the day is short and the light is low...I could purchase or borrow later kit 18-55 lens in spring and summer for landscapes especially...

May be I'll stay with 28-70 for some time on...To use it as my everyday-lens, and later could have some wide lens...

Deni and Little Laker, tell me some more for 28-70, what you really like about it and how often you use the lens...Some pics to show? Little Laker, what lens did you use here: British Columbia Scenic Landscapes ? Thank you.

Free Soul, I've had the lens for about 2 weeks or so, but so far it's the only lens I've used, except when I needed the low light capabilities of the 50/1.4.

Below are some photos I took with this lens during our company's End Year's Party (exif should be intact):

...Ummmm

My choice. None of the above...I would go for the Tamron 28-75 f 2.8 Lens....

Sold my 24-70 Canon after using it...When I was using Canon that is.

Ben, you have to understand that many of us don't really have the option of getting any lens we would like. The person who started the thread explained the position he was in and imo the sigma for $263 in Europe is a very good buy, that is if it is a good copy.

Free Soul,

The lens that I used for all my landscape photographs on that page is a Vivitar 28mm f2.8.
Sorry to say that it no longer produced.

however you can often find them used for less than $50.00 The series 1 is the best

Good luck with your decision.

I own the Sigma 17-70 in a Canon mount and find it to be a wonderful lens for the price. I almost went the route if a Sigma 18-50 f2.8 but backed away as I heard many stories of it being too soft wide open.

My vote goes with the 17-70.
