I need a wide angle plus a low apeture!

[Nessy024]

Im working with a nikon d3000 and i need a lens for 2 different occasions. One to take of indoor offices so i would like a wide angle lens with a low mm like 10. But im also doing an engagment photoshoot and i want to take a normal photo about 18mm butnwith the most blurred background i can (lowest number like 2.8? Or if theres lower?). So my question is there one lense that can do both of these features or do i need two different ones?

12-24mm DX 2.8 or 14-24mm 2.8

The 12-24 f/2.8 would be perfect but i cant find it anywhere for sale

That's because the 12-24mm (DX) is an f/4 lens, not f/2.8. The 14-24mm (FX) is f/2.8.

Engagement photos shoot with 18mm and blur background. It is going to be tough.
Either you cannot get the background blur or the subject distorts quite a bit when it is very close to the lens.

I think it is better to use a longer focal length lens with a wider aperture.

Ok so i guess ill just get 2 different ones. For the photoshoot im trying to get a background like this....Google Images but where the couple is in focus

Look for a longer focal length in the 85mm to 200mm range. Something else to look for is the design and number of the aperture blades. A lens with 9 rounded blades will produce a smoother out of focus background.

Tokina makes a 11-16 that is F 2.8,



Nikon makes a 10-24 f3.5-4.5 DX G or Sigma makes a 10-20 F4-F5.6... and Tamron also makes a 10-24 f3.5-f4.5. The Tokina has a good reputation.. don't know the others at all.. and of course the Nikon is Nikon.... Prices are $500 to $900..

Of course, none of these are going to have a super wide aperture (except the Tokina).. that would cost lots more money. I am thinking if you are shooting a 3000, that could be an issue?

I also agree that these would not be the best lenses for a Engagement photo shoot, unless you want the subject to be tiny with lots of distracting background. Or you can get close to the subject with these, and they will be distorted (sort of like those mirrors at the fun house that make you look fat)

What are you looking to spend? That would give us a better idea what to recommend....

There are 3 main ways to control the DOF (a shallow DOF can help to blur the background).
1. Lens aperture
2. Lens focal length
3. Distance to focus point (subject).

You can get a wide angle with a large aperture, but because of the short focal length, it will be very hard to get a shallow DOF. It can be done, by using the 3rd factor, and that would be to get the subject very close to the camera (and having the background farther away), but then you'll run into problems because as subjects get closer to a wide angle lens, you really start to get wide angle distortion....and that won't be flattering to your subjects.

So to get blurred city lights like that id need a higher mm lens...be far from the lights and have the couplde stand like 10feet from me? For the wide angle ill get a separate one...i basically need to take pictures of a rehab center outside and offices inside so i wánt to get the most i can in one photo of a small area

Nevermind very excited just learned its called bokeh and youtube has lots of tutorials!

I'll add a fourth element to what Big Mike said.

4. Subject to background distance.


In this shot, I was ~12'-15' from the subject and the trees in the background were ~30'-40' behind him. Shot with a 70-200mm at f/3.2, 1/60s (hand held too) at 160mm.

I think the OOF background is pretty smooth. Here's a 100% crop
.

Yep, pretty darn smooth to me.



The distances do play a significant role in controlling you OOF background, which helps to make the subject 'pop' on the page.

Or.

Get the Tokina 11-16/2.8. It's your best bet if you want great image quality, solid build, UWA, a zoom range, and an affordable price. If you don't mind about the price, the 14-24/4 is a great lens, but is only f/4 and 14mm. Buy the Tokina. Nuff said.
