What do you guys think about the Tamron 28-75 f/2.8? Good lens for walking around, and event photography?

Golf007sd: Just wanted to clear it up for the OP that there is no quality compromise by using a PRO or a FX lens on a DX body.

Agreed 100% With exception to my 10.5mm all of my lenses are Fx but all of my bodies are Dx...

I didn't mention it individually because it is covered in the "slew" of outdated lenses that still are (or were) "pro lenses"... Good lens though

I just wanted to add one lens to the "pro" lineup that is not AF-S. The 200mm F/4 micro, some have been wondering where the update for this lens stands though.

edit: of course if I would read all the words, such as the word "like" I probably wouldn't have mentioned it.

Can you elaborate on what do you mean by ".....you will lose the corners due to the crop factor."?

Are you saying you will get vignetting by using a PRO lense on a DX body like D7000?

I never had any problems using a 70-200 2.8 VR on my D90 pictures were sharp and clear from corner to corner.

Vignetting is not an issue on DX (crop sensor) dSLR's. What I meant was that when you use a Pro lens (Nikon's FX line of lenses...such as your 70-200 2.8) on a DX body (like the D7000) the image taken will not fully be represented at the focal length the lens was intended for. Hence, the image is cropped due to the DX sensor, thus all 4 corners not there. The picture below shows you what I mean.

Cheers...

he means the lens is different on FX than DX due to sensor size. FX works perfectly on DX in terms of quality.

As Kyos said, Nikon identifies their "pro" line of lenses by the Gold ring in the front.

As for it they will work on the D7000, yes they all do a fantastic job at that. It is just that you will lose the corners due to the crop factor.

That is generally true... Current main pro lenses 14-24mm f/2.8, 16-35mm f/4, 17-35mm f/2.8, 24-70mm f/2,8, 35mm f/1.4, 50mm f 1.4, 70-200mm f/2.8, 85mm f/1.4, 200mm f/2, 200-400mm f/4, and the 300mm f/2.8.

Also a few dx lenses like the 10.5mm f/2.8 and 17-55mm f/2.8 are considered pro as are tilt-shifts 24mm f/3.5, 45mm f/2.8, 85mm f/2.8, and super teles like the 400mm f/2.8, 500mm f/4, and 600mm f/4. In addition a slew of outdated lenses like the 14mm f/2.8, 80-200mm f/2.8, and 135mm f/2 are (or were) "pro lenses"...

Unless you thrash the crap out of you're lenses though any nikkor is great in terms of build (as opposed to many of canon's lenses and even a few L series lenses). Optically, pro lenses are much better than many of the non pro lenses, and most of the "pro" lenses perform very nicely (another area I've found certain "L" lenses to underperform in)...

If it is build you are looking for any nikkor is fine (believe me I know), as to AF, pro is better but the body determines that better (80-200mm f/2.8 AFD performs better on a D7000 or D3s than the 70-200mm f/2.8 VR2 does on a D70 or D100)

If optics are what you are looking for any pro (or ex pro) works nicely..

Used to be that EDIF lenses were the Nikon Pro lenses. Now, there are many different levels of Nikon lenses that might designate them to be within PRO status:
First of all, most "Pro" lenses have a constant f/2.8 or f/4 maximum aperture, and they certainly have the AF-S motor. They may or may not have VR, and some models may not be G lenses - but most newer lenses are G lenses (no aperture ring). You'll still see the ED glass designation, but you'll also see the "N" for nano-crystal coating. If you've got some or all of these items designated on your Nikon lens, it is a Pro Quality lens.

Noticeably build quality is the number one thing I see that is different. For some that alone can be worth the pro lenses over those that are not. They are usually faster lenses F2.8 or lower. They usually have more features...although this isn't always true.

I think they are worth it. They perform better. If they cover the range that you want to shoot or have a purpose for you then they are usually better performers than the lesser lenses. That being said there are some very good non-pro status lenses so I wouldn't let that alone be a deciding factor on which lenses to get.

Nikon doesn't have a naming label or a lens tier system, or anything similar to what other companies offer. It's not really a big deal though, since it mainly exists for marketing purposes. Just because a lens is marked professional doesn't necessarily mean it's any good, as you would still want to read reviews and examine it in person. And the opposite is definitely true.

Even though the "pro" labels are just for marketing, generally lens companies and their customers have the same idea of what they would expect in a good top quality lens. These would mainly be optical quality, build quality as well as ergonomics. Format, aperture or lens coverage doesn't really matter, but FX lenses tend to be more expensive, and so will be considered "pro" by many.

By how plasticy it is....

Unlike Canon most of nikon's lenses are built to a higher standard. Often the gold ring is the indicator but in general nikon really doesn't need to mark the pro lenses...

I know that canon has their "Pro" lenses know as the "L" series, and Tokina says Pro in the name of their pro lenses, so I was wandering how to know if a Nikon or tamron lens is Pro. Thanks in advanced? (Also, what makes a pro lens a pro lens, is it worth it for a DX format camera like a Nikon d7000?) <><
