It is only 4 days that I received the lens kit from the seller. I am not an expert photographer, and I own a D40.

Out door pictures are simply excellent & autofocus works very well. Additional flash lights are a must for low lit areas, but we can do without it in well lit indoors. Handling is smooth, a tripod would be of an added advantage, but with some experience, you can avoid shaky pictures.I will recommend this lens for this price you spend. Just enjoy taking new pictures!!

Seeing the incredible reviews for the vacuum I ordered it and have not been disappointed.

Pros:
1. Great price.
2. Feels sturdy and reliable.
3. Light weight.

The only con is that I no longer have an excuse not to vacuum!

As much as I love the 50mm f/1.4 lens there were times when it just was not wide enough. So I started an detailed search to find, for me, the perfect wide angle fixed focus lens.

As this lens will not get used a whole lot I immediately eliminated the ‘L’ lenses as too costly for the return. I was looking for something in the 20-30mm range. It needed to be a USM as non-USM lenses make too much noise while focusing and this lens will be used at plays & concerts. (I have the 35mm f/2 and it is way too noisy to use at these events.)

To make a long story short I selected the 28mm f/1.8 USM. This lens approaches the ’standard’ 50mm lens length that shoots pretty much what you see with your eye. It excells in dimly lit interiors, such as auditoriums, for instance. Use it wide open with confidence, but focus carefully – DOF is narrow even with a 28 at 1.8.

Pros: Lightweight, Consistent Output, Strong Construction, Rugged, Easily Interchangeable, Durable, Sharp Focus, Wide Aperture

Cons: my only complaint is the same as with all non L lenses, that I have to pay extra for the hood.

Totally different from your everyday read. At first, your wondering where is the author going with this, but yet she keeps you captivated. As you continue reading it gets better and better. It makes you laugh and it makes you cry. It has all the ingredients of being a best-seller. Highly recommended.

I knew the moment I heard about this lens that I’d need to get one. The chief problem I have with every other FX/film-sized wide angle lens is that they are either immense, heavy and extremely expensive; or quite mediocre* and not as wide as I’d like (and a few lens-generations old by now, as well). I had no doubt, given the excellence of nearly every recent Nikon lens, that it would be superb in terms of color, sharpness and focus performance – and only really wondered, before I’d seen it in person, whether its size would be appropriate for my use as a casual amateur photographer.

It is, almost, perfect.

First, though, having shot with it a fair bit now on both FX and DX, I can see that to convey an understanding of this lens and how it fits into the Nikon lineup it’s helpful to have some understanding of the difference between the design requirements of FX and DX lenses. This is something I’ve been writing about a bit in my recent reviews as I keep noticing the misperceptions implied by a lot of comments I’m noticing. I’m seeing comments already in reviews of this lens, for example, that it is bigger than it needs to be as a wide-angle f/4 zoom. I see comments in reviews of DX lenses that they should have been designed as FX lenses, so that they could work on both formats. And I see comments about nearly all zooms that they should have been designed with larger max apertures, even if it would have made the lens slightly more expensive.

All these comments reveal a lack of understanding about the inherent physics of optics and the design and manufacture of lenses.

For an FX lens to have exactly the same optics on FX as an equivalent DX lens would have on DX, the FX lens would need to be 3.4 TIMES BIGGER than the DX lens. This is because the FX format is 1.5 times larger in linear terms, meaning that the identical lens would need to be 3.4 (1.5^3) times larger in volume. If made of exactly the same materials it would weigh 3.4 times more than the DX len

These books seem to have transcended the high school demographic they were targeted for and I was curious what all of the hype was about when many of my friends and co-workers (most of them in their 30’s) became obsessed with the series. Literally, it was all they could talk about. After having muddled through the first book less than enthusiastically, I have to ask you people, what is so great about this series?!! I was bearly able to finish the first book because I couldn’t stomach another 35-page description of why Bella is so accident-prone, or how for the 75th time she hoped she would see Edward in the cafeteria and he didn’t show up. The whole book seemed to be a conversation between the two of them about why they shouldn’t be together, but what the heck let’s give it a try anyway. It was pretty much like reading a 13 year old’s 400 page diary. I am not a literary snob in any way- as long as it’s a great story, I’ll read it. But this book was seriously disappointing- don’t waste your time.
