Ruben Silva Posted October 1, 2006 Share Posted October 1, 2006 Hello,I will appreciate your comments on each of these lenses, as a travel mid-range zoom. How about optical quality?Regards Link to comment Share on other sites More sharing options...
Ed_Ingold Posted October 1, 2006 Share Posted October 1, 2006 You must have a DSLR if you're considering a DX lens. 28mm is equivalent to a "normal" lens (42mm) in this case, and is not wide enough to be useful as a walk-around lens. A lens starting at 17mm (25mm equivalen) would be better. Otherwise, it is impossible for anyone to comment without knowing the camera and manufacturer of the lenses.

richard_laepple Posted October 1, 2006 Share Posted October 1, 2006 When I got my D70 (+18-70) I sold the 28-105 which was my standard lens in film times. The 28-105 is a great lens and I was always satisfied with it, but, as said above, for the use with a DSLR it's a bit long. Because I have no film Nikon any more keeping the 28-105 did not make sense for me. If you still use film you may be in another situation. Link to comment Share on other sites More sharing options...
Ruben Silva Posted October 1, 2006 Author Share Posted October 1, 2006 Thank you .. Richard, one question, how would you compare their optical quality? regards Link to comment Share on other sites More sharing options...
richard_laepple Posted October 1, 2006 Share Posted October 1, 2006 Ruben, I do not make scientific comparisions between lenses. IMO you can't go wrong with both. The 18-70 has some distortion and vignetting at the wide end. I can't remember if the the 28-105 looked the same with film, probably not. The 18-70 is great to use on a DSLR because of the fast focussing motor. Link to comment Share on other sites More sharing options...
steve_fu Posted October 1, 2006 Share Posted October 1, 2006 I have both because still shoot slides. The optical quality of the 28-105 is better because only the sweet spot of glass is used on DSLR. The 28-105 also reaches further if you like to use the long end. The 28-105 also provides the semi-macro mode that allows you to get closer and fill the frame more. But it is not as wide. The 18-70 is wider on DSLR, obviously. But it suffers from vignetting when wide open at both the long end and wide end. The edges are not as sharp as the 28-105 on DSLR (see my samples). It is a tad darker than the 28-105 (see my samples). The AF is quieter than that of 28-105 but the AF speed is about the same. I decide which one to mount on D100 based on my mood. :-) Two full size samples can be found at http://www.photo.net/photodb/folder?folder_id=116382 Link to comment Share on other sites More sharing options...
ShunCheung Posted October 1, 2006 Share Posted October 1, 2006 If you are looking for a lens for a Nikon DSLR since you are talking about a DX lens, 28mm is not all that wide as a general-purpose lens. I would definitely get something that starts from 18 (or 17) mm. That are good reasons that Nikon has introduced 4 different 18 to xxx DX lenses in the last 3 years.
