I got my 18-35mm just yesterday and used it today for real estate. I bought it used for 200 USD so there is no chance I would regret it. I use it on a Nikon D700 FX so it gets REALLY wide. The lens is pretty sharp even in the corners, though you will notice that they are less sharp especially wide open. The build quality is mediocre and it feels like most cheap plastic zooms from Nikon. If you are a haptic it is not so nice but if you are looking for something light weight it is great. I handle my glas with care no matter if it is plastic or metal so I don’t really worry. I use it with a Hoya UV filter which does not cause any vignetting/dark corners. The only problem is that this lens hast quite some distortion at 18-24mm. I tested the Nikon 20-35mm before which has almost no distortion but is not as wide, costs more, weighs more and is not as sharp. So this lens is probably the best compromise if you don’t want to spend a lot of money on a 17-35mm or even 14-24mm.
Nikon 18 35mm f

This lens is regarded as one of the best three prime lenses that Canon produce (Along with 85mm f/1.2 L USM and 35mm f/1.4 L USM).

The images from this lens are very sharp, contrasty and show a lot of details even in wide open at f/2. The depth of field is very shallow at f/2. As a result, the background will be compressed.

Because of that features, Canon 135mm is ideal for portrait, especially candid portrait, street photography and indoor sports.

Build quality is very good, the best Canon can made. The lens is not as big and heavy as telephoto zoom.

But unfortunately, this lens does not have Image Stabilization built-in. Image stabilization in telephoto is quite important so you can shoot with shutter speed lower than the focal length X crop multiplier. For example, when you attach this lens into crop sensor camera such as Canon Rebel series or X0D series, then you need to set a shutter speed to at least 1/200 or greater to get a tack sharp result. It is also depend on how steady your hand is. If you have steady hand, then 1/160 will be adequate.

This lens have a decent closing focus (1m) this is better than most of the telephoto zoom range. You can also get a extension tube to get the focusing even closer (.6m with 2x extension tube). Therefore, this lens will be quite good for macro photography.

Application
The application of the lens will be quiet narrow. Candid photography is one in my mind when I think about this lens. It is because the telephoto range, maximum aperture, and the size is not that big and obtrusive.

The second one will be close-up and head-shoulder portraiture, and then for indoor sports such as volleyball, basketball and so on.

The downside
This lens does not have a wide range of application because the inflexibility of fixed focal length lens (prime lens).

Although the focusing is quite fast, but it is not as fast as EF 50mm f/1.4 USM or EF 85mm f/1.8 USM. The AF tracking is poor. So in the fast action sport, expect to miss some shot

This is a GREAT cleaning machine and very reasonably priced. I used it both for carpet and upholstery cleaning and it did a terrific job.

ECONOMICAL:
This is an inexpensive vacuum that gets the job done. It does not have all the bells and whistles, which for me means less that can break down. I had been looking for a decent vacuum that wasn’t over priced. Consumer Reports had done vacuum reviews and placed this among the better upright vacuums you can buy. I was really looking for something with power and the ability take care of cat hair. I decided to purchase this and I got what I paid for and more. The vacuum indeed has the power and ability to get up animal hair with ease. I vacuumed every room and then looked in the bag. It picked up so much particulate and animal hair, big improvement over the more expensive vacuum cleaner I once had. Ya, it doesn’t have a bag indicator or a head light, but my old vacuum had those and I never used them(indicator accuracy was questionable). The vacuum is light weight and easy to push (big help for my back). It has a secondary and final filter, both helpful in keeping the motor safe and returning clean air into the room.

BELT WORRIES:
My big worry when buying this was the complaints about the belt breaking. No such occurrences for me. I have used this vacuum extensively, no belt damage has occurred. Huge tip for those with this problem or those who are wanting to buy this vacuum –The height adjustment on the vacuum is there for a reason. Do not put it on the bare floor setting and vacuum a shag carpet. You will destroy the belt and cause premature wear on the motor and/or other components. In my case, I adjusted the brush height so that the vacuum just barely crawls when on and the brush is lowered. This lets you know it is loosening up the dirt and not trying to dig a hole in the carpet. If the vacuum is pulling you along, this is an indicator that the brush is too low. Also, try not to run over clothes or the edges of throw rugs for this can also cause belt damage or breakage. Simply put, adjust the agitator brush to the height that the job requires.

Hi, I’m 37 years old, running Marathon and less.
I used the Garmin Forerunner 405 in the last 18 months and decided to replace it with
the Garmin 305 Forerunner (yes, you read correct – i bought the 305 over the 405)
and i am very happy.
I am much more satisfied now:
- The on-going pace is much more accurate,
- the screen is clear and easy to read (405 is too small)
- It synchronize with satelites faster
and above all:
- It is easy to use with push-buttons (thanks god i no longer need to use the “”touch screen”").

Yes, it is a little big and a little heavy, but this is surely neglected!!!
you get used to it by the 2nd run.
The only doubt you should have when thinking of buying the Garmin 305 is whether you are
willing to spend more money and get the Garmin 310x.
I decided not to, and i am good with it: By saving 200$ the meaningful lost is not having
a vibrating alarms. Which is a very good idea, but i can manage without it, and with the 200$ i saved
Good luck and good run.

Until the 32GB SDHC cards come down in price, this 16GB gives you the most space per dollar. Been using this product in my Canon Vixia HF S10 for about 6 months now and it’s never failed me.

I tested out my lens by taking non-flash photography at a table tennis event. The pictures turned out very well. Only a few shots were blurred but that may have been due to camera shake (I didn’t even use a tripod).

I enjoyed the book very much! For me, it was a “can’t put down” book and I would recommend it to anyone who likes a good story!
Sigma 70 300mm F

The most telling quote from the book, “There is no such thing as right or wrong,” and God is supposed to be saying it. If that is what you are teaching your kids, this book is for you. Otherwise, if you believe in morality, that some things are wrong, like killing or stealing, this book will undermine your parenting.
