    Sigma 17-70 2.8-4.5 OR Nikon 18-70 3.5-4.5 (D70 kit lens)

    Alright, I know I asked the question a while ago about the wide angle lenses, and probably in the end I will go with the Tokina 12-24, but now I want to know your thoughts on an every day walk around lens.

    I want a nice walk around that can fill my missing gap between 55 and 70 mm, and that has a fast apaeture because I want to avoid using my flash at all costs. I know there are 24-70 2.8's out there, but I would have to swap out lenses if I want to take any photos indoors. 18-55 is nice, but I want that extra length. Its unfortunate that no one makes a 18-70 2.8, but I guess you have to work with what ya got, or others make. Anyways...

    I have read great reviews about the Sigma 17-70 2.8-4.5. From what I am hearing, everyone loves the lens and cant complain about it. The only other lens that compares to it would be the Nikkor 18-70 3.5-4.5 (D70 kit lens). Same range, same price (brand new), but the Sigma beats the Nikkor out in apaeture, distortion, and macro capability.

    Heres my dilemma. Do you go with the first party lens because its a first party lens, or do you go with the third party lens and call it a day.

    I have seen a guys comparison between the two on this site somewhere, but they were both pretty close in the test shots.

    Did anyone with the kit Lens swap for the Sigma? If so, why, and are you happy with the decision?

    Anyone with the Sigma wish they would have gone with the Nikkor lens?

    There's your answer :-) However, Sigma has only a minimal aperture gain and then only at the low end.

    "Did anyone with the kit Lens swap for the Sigma? If so, why, and are you happy with the decision?"

    I bought a body only, and so avoided a "swap". I don't really miss the 50-70 gap myself but I did want a good, fast low-light lens though if I had to give up one lens that would be it.

    It's always tempting to go with your body-name lens, but third parties make good things, too.

    2 of 3 lenses I have are Sigma and I have no complaints. Both of them show up occasionally in people's gear lists.

    You have a Tamron, so apparently you are already thinking outside the box :-)

    I think that the Sigma only has f2.8 at 17mm, as soon a you zoom, even a tiny bit you loose the 2.8 aperture. If that's the case you won't gain much over the Nikon lens in terms of low light performance.

    Having had both lenses I would have to agree with K1W1. In everyday use you will not notice much benefit with the 2.8 aperture. You loose it with just the slightest zoom. The big benefit of 17-70 sigma is the macro capability. I picked the sigma over the nikkor and sold my 18-70. As a walk around lens the sigma does have a big issue with the zoom creeping unless zoom lock is used when wearing the camera around your neck. If your looking for low light lens go for a constant aperture lens over it whole focal range. I am working towards constant aperture lenses to replace all my lenses. I still have comparison pictures in my gallery. I used to have a webpage with more information back when I took the pictures but I have since deleted it and just incorporated the pictures in to my gallery.

    So then I take it from your reviews that I should probably just so with an 18-50 2.8. Price is fairly similar between the 17-70 and the 18-50, and with the larger aperture it should prove to be a better lens.

    I think Ill put in an order today for one and see how it turns out. Hopefully it wont be a crappy copy. If so, hopefully they can get me a good one before Christmas.

    Yeah the 18-50 f/2.8 from Sigma should be a bit better because of the constant aperture. Hope you get what you're looking for.

    Well, I just ordered the Sigma 18-50 F/2.8 EX Macro with a 72mm Hoya UV filter from B&H. Hopefully I can get it sometime next week just in time for the holidays.

    I tried out the Nikkor 50mm 1.8 at the store today.... I'm still undecided about purchasing something like that. Im just not used to prime lenses. I guess Ive been babied by zooms all my life. Not to mention, I couldn't get the depth of field effect that I wanted unless I treated the lens like it was a macro lens. Hmm... I will have to think about that one some more. But Im not in a rush to get it.

    I did not know they had a "macro" version, but my "normal" one takes a 67mm filter. A few websites have it wrong.

    Yep, the Macro just came out. No body has really reviewed it yet, but I found some comparison photos on some Japanese website. From what I could see, better edge to edge performance and less chromatic abberation than the regular 18-50 F2.8. And with the macro capability, it makes it just that much nicer.

    The macro lens takes a 72mm filter now.

    I know I could have waited until Tokina came out with their 16-50 F2.8, but no one even knows when it is coming stateside, and I haven't found any reviews on it yet. Not to mention its price tag is figured in the $600 range.

    You'll be very happy with that Sigma. it takes great pictures. I would like to see you post some samples of pictures taken with the filter on and the same pic with the filter off. Myself, I think filters arent needed but I would like to see what you think about them with comparative shots. Enjoy your new lens, shes a 'bute!
