Any lens that is around $50.00 is probally not worth the money to ship it.

After reading your question, I had the same thoughts as BigGWells has stated. It is a great lens.

Hey Light House... If you mount a 24mm fx lens on a dx cam the crop will be more and you will lose image area around the edges of the photo. It would be equivalent or close to the image size of a 35mm dx lens on the dx cam. 1.5 x 24mm = 36mm.
C8...you need a wide angle dx lens to shoot real estate interiors. 10mm to 17mm dx would work. Expensive though. If you go under 10mm the edges of the photo would resemble fish-eye and need heavy post processing or may not be usable at all. The 18-55mm dx kit lens would probably be the cheapest lens but would be at the wide angle limit for interiors.

A 24mm FX lens and a 24mm DX lens give exactly the same image on a DX camera. I agree, though- you need something a lot wider.

show us a sample?
Too many pans in the fire to do one right away.
I posted one last year answering this very question.
A DX or an FX (or medium or large format) lens of the same focal length all have the same magnification.
The image circle they project is different due to the design & needs of the format for which they are intended.

This is getting ridiculous. The recorded image from a 24mm fx lens mounted on a dx cam is not the same as a 12mm dx lens mounted on a dx cam. The smaller sensor size of the dx format will crop out the edges of the image from the 24mm fx lens to make it look like a 36mm dx lens image circle. You are forgetting the crop factor for dx at 1.5. You should test you theory.

Who said anything about a 24mm FX lens being the same as a 12mm DX on a DX camera...besides you?
Read my freaking post!!!
Ok- here is a test with two lenses on a DX body, a Fuji S5pro-
1 is a DX 10-20 set on 12mm
The other is an FX 12-24 set on 24mm.
There is a little difference due to an inaccurate zoom ring, but not anywhere near 1.5x.

On the cheap look for a Nikon 18-55. One on local Craiglist is $90.
Probably 18-105 should be fine also.
Long term though something like the Sigma 10-20 is what you
really need. I use this one for our listings w/ D-90 and very good.
I still carry the Nikon 18-105 along but rarely use.
We also use an outside photo/video service for some listings and
notice that even with their higher end cameras & gear many of
those folks use the very same Sigma.
If you don't have a flash attachment and will use on board flash
best to go with 18-XXX. With the Sigma 10-20 on board flash
often will cast a shadow on the lower portion of the photo as the
flash projects over part of the wider lens barrel.

Its absolutely amazing how many people refuse to understand the so-called "crop factor" when related to lenses, no matter how many times it is explained to them.

I typed as slowly as I could.
When I did this test about a year ago with the Nikon D7000 using a DX 17-55 and an FX 24-70 both set to 35mm, the images were virtually identical...better engineering?

Edit....Now you've got me doing it...correction..both are set on 12mm!
