chris_moore10 Posted April 5, 2008 Share Posted April 5, 2008 Hi all! I will be recieving my D300 soon (sooo excited!) and I'm getting into the fashion industry and need some assistace from all of you I'm going to require a fast zoom lense for the catwalk photos that I'll be taking (plus this will help with everything else that I'm shooting)and can't afford the flag ship 18-50 2.8 Nikon. My issue is price primarily, but also the digital crop will be an issue when I select my lense. I'm looking for 28-70mm lense 2.8 lense, but I don't know what lenses change with the crop and which ones do. Can you help? Link to comment Share on other sites More sharing options...
niccoury Posted April 5, 2008 Share Posted April 5, 2008 The DX equivalent to the 28-70 is a DX 17-55 f/2.8. It's about $1,200 USD. A fast tele might be good too. Like the 70-200 f/2.8 AF-S VR. Link to comment Share on other sites More sharing options...
hbs Posted April 5, 2008 Share Posted April 5, 2008 "My issue is price primarily" -- The Tamron 17-50mm f/2.8 is a $450 alternative to the much more pricey 17-55 Nikon and, from all the reviews I've read (plus my own experience with the Tamron on my D300), is an excellent lens that you may want to consider.

brian_weinkauf Posted April 5, 2008 Share Posted April 5, 2008 First off, save your money and get the lens you really want/need. If you don't you will be unhappy and you may end wasting money if ungrade later. Buy nikon! (better quality and better resale). You just spent a bunch of money for a great camera. Why put cheap glass on it? The glass IS the most important part. Nikon's crop factor is 1.5. So 100mm on film or FX is 150mm on DX. Personally I would get 24-70/2.8(new hard to find), the older but still great 28-70/2.8 or 70-200/2.8. If you have to get the 18-200mm f3.5-5.6. The focus is reasonably fast, but you are giving up some aperture. Or get a prime or two cheaper and fast, but no zoom. Good luck Link to comment Share on other sites More sharing options...

hash Posted April 5, 2008 Share Posted April 5, 2008 If money if the issue, buy used glass rather than buying cheap new glass. Most people here would recommend www.keh.com. Even their bargain lenses are in very good condition. You can sell tham later for almost the price you paid, or sometimes even make a profit.

rduran Posted April 5, 2008 Share Posted April 5, 2008 My recommendation is to start with the tamron 17-50, I am very pleased with it after 1 month of use. Then, if you really need it, head for a Nikon lens. Link to comment Share on other sites More sharing options...
juan_parm_nides Posted April 5, 2008 Share Posted April 5, 2008 Chris, I use both lenses in my cameras: the Nikkot 17-55 f2,8 and the Tamron 17-50 f2,8. The optics quality is the same in 99% of situations, the Nikkor is better built and is a lens for hard work and surely will last more. But, as you said, price is important, I would recommend you the Tamron. Link to comment Share on other sites More sharing options...
don_cooper Posted April 5, 2008 Share Posted April 5, 2008 "I'm looking for 28-70mm lense 2.8 lense, but I don't know what lenses change with the crop and which ones do." - The simple answer is that ALL lenses have a 1.5 crop factor with Nikon bodies except for the D3.

ray_du_bois Posted April 5, 2008 Share Posted April 5, 2008 You can get a 35-70 f2.8D for a good price if you can still find one. Link to comment Share on other sites More sharing options...
seandepuydt Posted April 5, 2008 Share Posted April 5, 2008 Chris my 28-70 doesn't leave my D300 very often. If I need a wide view I've found the 18-70 a nice fit. Link to comment Share on other sites More sharing options...
jim_orr Posted April 5, 2008 Share Posted April 5, 2008 It runs about 400.00 and is very sharp. The Macro is not a true 1-1 but I have shot some awesome wedding day macros that turned out great. Well worth it. Link to comment Share on other sites More sharing options...

chris_moore10 Posted April 6, 2008 Author Share Posted April 6, 2008 What I should add (that'll make a little more sense) is that I'm looking for a lense that will always give me a 24-70 focal lenght range and a 2.8 aperture. My concern is that with the 18-50mm and the 28-70mms lenses is that I don't know which model will become a eg 42-105mm or a 27-75mm. I've been to www.photozone.de that has awesome details on all lenses but some aspects of the site aren't specific with exact focal lengths... But thankyou all for your help Link to comment Share on other sites More sharing options...
Richard Williams Posted April 7, 2008 Share Posted April 7, 2008 Chris, sounds like you don't quite understand the crop factor thing. The focal length doesn't change when you mount a lens on a camera with a smaller than 'full frame' sensor, it's always what it says on the barrel. If you want a lens for the D300 that gives you the same angle of view as a 28-70 on a 35mm camera (or on the 'full frame' D3), you need a lens that covers a range of about 18-50mm. Here's one quite good explanation: http://www.the-digital-picture.com/Canon-Lenses/Field-of-View-Crop-Factor.aspx The D300 has a 1.5x crop factor, so you can look at ANY lens on photozone and multiply the focal length by 1.5 to see what the 35mm (or FX) equivalent would be. It doesn't matter if it's a DX or FX lens (both will work with the D300) - the crop factor is the same. The DX lenses, however, won't cover a full 35mm frame or a DX sensor, so they're only (generally) suitable for DX cameras. Link to comment Share on other sites More sharing options...
