Sigma 24mm f/1.8 EX DG Aspherical Macro Large Aperture Wide Angle Lens for Nikon SLR Cameras Price



I purchased this lens, then barely used for the first few months. One day I was in a creative rut, so I decided to spend a day taking photos with only the lens I used the least. That day resulted in this becoming a favorite lens. On my 40d it’s equivalent to around a 38mm focal length, which I find to be quite versatile.

Tamron AF 18-250mm F/3.5-6.3 Di-II LD Aspherical (IF) Macro Zoom Lens with Built In Motor for Nikon DSLR Price



Beauty is in the eye of the beholder and so, I think, is one’s opinion of a camera lens. I’ve learned over the years that lens reviews are helpful, but they are just opinions. Yes, for sure, you generally get better optics with more expensive lenses, but it’s certainly not a guarantee. And for reasons one can only wonder about, oftentimes two copies of the same lens will produce very different results. For example, my friend Sara, who is as nuts about buying (we’re like compulsive buyers) and using Canon lenses as I am about buying and using Nikon ones, has a Canon EF-S 18-55 kit lens that produces images so tack sharp through its whole range that would make you cry.

Tamron 18-250mm F/3.5-6.3 AF Di-II LD Aspherical (IF) Macro Lens for Nikon Digital SLR Cameras Price



Apparently, this lens is available in two versions for the Nikon. The AF018N-700 does NOT have a built in motor for AF. The AF018NII-700, does. If you want AF and your camera does not have an AF motor in the body, make sure you get the lens with the motor. Reading through the reviews on this page, it seems that people are reviewing the two different lenses here, thus the confusion. This lens does not have a motor. The AF works fine with my D300, but not with my D3000.

Feature

  • Advanced Optical Design
  • Internal Surface Coating to Reduce Ghosting and Flare
  • Zoom Lock Mechanism
  • Di-II Series Design

Sigma 24-60mm f/2.8 EX DG IF Aspherical Wide Angle Zoom Lens for Nikon SLR Cameras Price



So maybe I am very lucky. My copy of this lens is superb. Yes there is a difference in sharpness when shooting at 2.8 but it is still very sharp and once you go smaller than the 4’s it is SHARPER than comparable nikon lenses.

This lens is quiet, focuses fast and zooms smoothly on my D80. All three of these things are issues others have had but I do not have. Cameta has a good return policy so why not try it at this price? I am happy I decided to go for it and feel like it is one of the best deals in my bag. Please note: (I have several fast pro Nikon lenses I have compared this too when making my review, not just other 3rd party lenses)

Tamron 18-250mm F/3.5-6.3 AF Di-II LD Aspherical (IF) Macro Lens for Nikon Digital SLR Cameras Price



Awesome everyday use. I get lazy when switching out lenses.

Pros- when I want to shoot macro, fairly simple. When I want a wide lens shot- I got it. All in-one-feature. HAPPY with results (color wise- amazing, depends on technique).

Cons- not much, other than I wish I can zoom in more? I need to purchase a hardcore macro lens++. I love abstractions from zooming in super close!

Overall- NICE..

Sigma 24mm f/1.8 EX DG Aspherical Macro Large Aperture Wide Angle Lens for Nikon SLR Cameras Price



Let me put the light gathering abilities of the Sigma 24mm F/1.8 lens in perspective.

The Olympus 14-42mm f3.5-5.6 kit lens, at wide open aperture and set to a 24mm focal length, is an f/4.7 lens. Ouch. With the kit lens wide open and set to 24mm focal length, I need 1600 ISO to get a tripod shot of my kitchen at around 1/50th of a second. With the Sigma, I get the same shutter speed with the camera set to 200 ISO. At 1600 ISO, the Sigma shoots the same image at 1/400th of a second.
