5 Stars Better alternative
This is a better alternative to the kit lens you get with your Nikon, this lens is better built. This lens is more durable, and it can take photos in lower light which makes it faster.

4 Stars Petite, nicely put together, sharp
I bought this lens mainly to go with my little Nikon D60, and I’ve been pleasantly surprised by it. For the roughly $100 I paid for it, it’s turned out to be quite a good lens. I originally bought this lens because of it’s tiny size. I also own the Nikon 18-55 VR which is a nice lens, but it was just large enough to be extremely difficult to wedge into or pry out of the small case area I have for it, so I thought I would try this lens out. It’s enough smaller than the Nikon lens that it fits about perfectly into the case I wanted to carry it in.

Pros:

- the lens feels better constructed than the Nikon 18-55 VR. It’s not so much that the Nikon 18-55 is horrible(at least in comparison to other similar lenses), but this lens does feel a bit more solid and above average. Does it matter? Not much to me, although the metal bayonet mount is really nice to find in this price range.

- I can’t see any difference in sharpness between this lens and the Nikon 18-55 VR. I’m not saying there isn’t any difference, there might be, but I haven’t been able to see it. This a good thing, since the Nikon 18-55 that this lens supplanted has been a sharp lens. That’s not to imply that this lens is as good as a $1200 pro lens, but in comparison to the other similar lenses I’ve tried, this little Sigma isn’t lacking in the sharpness department.

- it’s tiny. It’s barely larger than most prime normal lenses.

- focusing seems really fast and precise, more so than the Nikon 18-55 that I own.

- inexpensive.

Cons:

- like all inexpensive, small sized lenses, it has a fairly small maximum aperture, f3.5 at 18mm to f5.6 at 50mm. Not a problem for me, and not really a con, it’s a trade-off to get the size down and keep the price reasonable.

- Sadly, no OS. Again, I can live with it the way it is, since VR would make the lens larger, and maybe a little more expensive.

The more I use this little semi-precious gem the more I like it, and the more convinced I am of it’s excellent value.

5 Stars Great Lens, awsome price, fast shipping
If you have never owned a sigma they are every bit as good as a Nikon for all but the most demanding professional photographs. I’m sure the expert photographer can tell the difference but my dad (who teaches photography at a local college) swears they are every bit as good for a fraction of the price

4 Stars Affordable good performance
Right out of the box instructions were easy to follow. Lense quality is fairly good. I thought that for the price I would get something “cheap”; wrong. Very sturdy. Take the time to read the setting instructions and you will get very good/excellent results.

5 Stars Food photographer
I like to take close ups of food and from my use of it so far, it is a great macro lens!

5 Stars Great Lens For the Price
I do a lot of photo editing with the pen tool and wanted a lens that had less chromatic aberration than my kit zoom. I am very satisfied with results and the speed. I had initially seen a review of this lens on the Photoshop User website. If you are looking for a prime lens and are on a tight budget this bears looking at. I am shooting with a D80.

5 Stars A must have lens!!!
This lens is a must have. It will instantly make you a better photographer. I’ve used this lens on all holiday events inside the house and all pictures are perfect. It’s great for low light photography, portraits and it also produces a nice bokeh. This lens has always been in my camera ever since I had it. Well worth the money. So far I’m very satisfied with this purchase.

5 Stars As Advertised
Lightweight and fast, this lens works beautifully with my D40. The autofocus is accurate, but the ease of manual override is a nice advantage. If you’re thinking about buying one, you should.

5 Stars Lovely fist full of prime lens
As others have noted, while it’s mostly plastic, it’s got a heft to it that says serious lens. This is my lens of choice whenever I can fit the subject into its field of view. I love the low-light ability and the sharpness of the resulting photos. Hard to beat the price, either.

5 Stars Sharp and fast lens!
I use this lens far more than I thought I would. It is sharp across its entire f-stop spectrum, and very sharp from f/2.0 through f/11. No discernible chromatic aberration. An ideal indoor / low light lens.

5 Stars What a difference!
Wow, totally dig this flash! After using the built in flash since owning my D40 (& not being happy with the results alot of times!) for 2 yrs, this is so refreshing & inspiring! I saw reviews on amazon with photos of what this flash does & it’s totally delivered Beautiful results from bouncing the flash off the ceiling. This was one big easy step in furthering my photog hobby skills!

4 Stars Fantastic lighting upgrade
I have have been using this unit for 2 weeks and am impressed with the improvement offered with indirect light bouncing off nearby surfaces vs the on-board unit. The SB-400′s capability to aim the flash in multiple angles is not thoroughly detailed in store or official documentation when it is easily its greatest feature. I sometimes wish I whent with a flash with a bit more horsepower and twist aim, but I figured learning the art was more important than the gadget. Overall a simple no frills great improvement from my D5000′s on board flash.

5 Stars For users with a Nikon with ittl only “D40″
This add-on flash is compact and works flawlessly on Nikon camera with iTTl systems. Using the built-in camera flash will consume your cameras’ battery life a lot faster this possible causing you to lose that perfect moment. There are huge benefits of bounce over compared to the direct flash on the Nikon model and body you own, maybe overwhelming. This unit gets great reviews for its size and its multi angel bounce, this unit will bounce off high ceilings and distant walls but it’s great for many occasions and engagements.

Overall by using this unit instead of the built-in flash of one’s camera, you will get more shots from the camera since its power source is two independent AA batteries and not the camera. It’s compact it’s great for its size ability and price.

3 Stars Not as good as the SB-600
I got this to go with my Nikon D40. It is an improvement from the built-in flash for sure, but not as good and versatile as the Nikon SB-600 Speedlight Flash for Nikon Digital SLR Cameras. I ended up returning this one and buying the SB-600 instead.

Pros for the SB-400 are size and price – best for portability. It is definitely an improvement over the built-in flash for light quality and ceiling bounce.

Biggest weakness is that I can’t use it for portrait photography bouncing off the ceiling. Please see review of Stroboframe Press-T Flash Rotating Bracket for details.

5 Stars Travel Light
While not as versatile as the more expensive and featured Nikon flashes, it does the job while remaining small enough to throw in the camera bag for small events, parties, day trips, etc.
