Hello guys

I was reading a little about that and I still need a little more info about DX and FF cameras.

I have a Nikon D3400 with the kit lens 18-55mm, is that a real 18-55mm effect with my camera or do I have to multiply for 1,5?

Do I have to multiply all lenses for 1,5 or only those that are made for FF?

Probably something very easy but I'm a little confused 🤣

Thanks

All of them. The field of view changes with crop sensors.

OK, so even when my kit lens says it is 18mm it is actually 27?

I am considering to buy a 10-20mm, so that means I'll get a 15-30mm, right?

Yes.

Now I understand everything guys, thank you!!!

The 18mm is 18mm lens and not 27mm. The 18mm give you the same view on the DX camera as the 27mm view on the FX camera. So unless you used to use the FX camera and familiar with the view of the 27mm on the FX the crop factor does you no good.

OK, maybe I don't understand 😂😂

I want to buy this one, how it will works on my D3400? Will I see a good different between my 18-55mm for landscape?

The crop factor says that the lens will work on your camera like a 15-30mm on a FF camera. Now unless you know how a 15-30mm lens works on the FF camera it does you no good.

Get two 3x5 cards. First one cut a 1 1/2 x 1 inch hole in it. Second one cut a 1 x 2/3 inch hole in it. Hold one a foot in front of you what do you see, now the other card. Two different field of views, but your lens did not change. The large hole is f2f, the other the cropped senso.r

Getting a 10-20 will still get you a 10-20. The field of view will be similar to that of a 15-30, But it's still a 10-20. If you were to take a 30mm on a full frame and a 20mm on your camera and point it at a subject, let's say a building - that is 30 ft away and the lens is set to F2.8, the field of view will be the same if you are standing in the same place. However, one quick look at a depth of field chart or calculator will show you that the DoF on the 30mm/FF camera will be from 12.7 ft to 34 ft. On the 20mm DX camera the DoF will be from 10.8 ft to 131.4 ft. Putting the 20mm on the full frame camera will give you not only a much wider view (assuming the lens will cover the larger field), and the depth of field will be from 8.74 ft to infinity.

When you look at an image taken with an iPhone which has a 4.2mm lens, the depth of field is crazy deep - from inches to infinity.

DX-only lenses are physically smaller, since they don't have to cover a larger image field at the sensor. FX lenses will cover both.

These are subtle but important differences.

If this makes sense, now you can say that you understand everything.

When I use the 18mm and put at 26mm I don't see so much difference, and it is 8mm difference.

So, will I see a good difference if I go -8mm (10-20mm) since it says "wide angle lens"?

Do it the lens worth the 350$?

I am afraid you are confusing him more than he already is. The 18mm lens when used with a DX camera like his 3400 will give him a field of view similar to a 27mm lens when using a FX camera. Once he uses the lens he will understand what the crop factor is doing. What he needs to know is that when using a wide angle and due to the expansion of the background that results from the optic he will have to come closer to the subject for a more striking image. The corners will show distortion but that is characteristic of wide angles lenses. I do not know if the Nikon 10-20mm lens will work with his D3400, that is for him to find out.

You have to consider also when you go with an extreme wide angle lens like the 10-20mm, distant objects can appear small. Often, it's better to use a longer focal length.

SUBJECT SIZE
When using a wide angle lens, you'll often be positioned very close to your subject. This makes foreground objects appear very large in the frame, and distant objects very small. Wide angle lenses also exaggerate the distance between objects, making subjects at moderate and far distances seem further away than they really are.

You might want to rent first to see which lenses would be right for you. LensRentals.com is very good. I've rented from them numerous times. They include a pre-paid shipping label to make returns easy.

Ok guys, I THINK I'm starting to understand.

So why in many webs people says that wideangle is good for Landscape and Real Estate photography?

NOW I see why is good for real estate, it will make house's interior looks bigger, right?

But is not necessary the best for landscape then, right?

I put to of my photos so you guys can see the photos I like to take.

To rent is a good idea, I'll check it out if there is possible to rent lens here in Norway. Thanks 👌
