$*$ Sigma 70mm F 2.8 EX DG Macro Lens for Canon Digital SLR Cameras



[[ASIN:B000GPKQHQ Sigma 70mm F/2.8 EX DG Macro Lens for Nikon Digital SLR Cameras]



Prior to purchasing this lens, I did my research on macro lens, comparing technical specifications, prices and manufacturing countries. Contacting Nikon USA, the representative could not tell the manufacturing country. I had bad experience of owning a Japanese brand, made outside of Japan. Guaranteed by the manufacturer's brand name is not good enough. I like to buy and use a quality lens, not a brand name!!!! When I contacted Sigma USA, I got a positive reply that the lens is made in Japan.



Great macro lens on my Nikon D700.

Picture quality: Excellent. 9 Diaphragm Blades creates smooth bokeh, great for portraiture.

Workmanship: Excellent

A full frame lens for serious photographers.

Competitively priced at Amazon.com.



Highly recommended.

-- Sigma 4.5mm f 2.8 EX DC HSM Circular Fisheye Lens for Canon Digital SLR Cameras



Combined with Nodal Ninja rotating tripod heads, I'm using this lens to produce equirectangular 360deg x 180deg panoramas. Six shots in 60deg increments work perfectly when stitched with Hugin or AutoPano.



Limited depth of field is a problem --- I find that typically I have to operate the lens at f/11 or f/16 to get decent full-frame-in-focus results, which necessitates shutter times of > 0.5s indoors, so it's only really useful for static scenes.

#@: ASUS UL30A X5 Thin and Light 13.3 Inch Black Laptop 12 Hours of Battery Life



I was looking for a replacement machine after my Dell XPS M1330 unexpectedly died on me. I was initially primarily looking at netbooks, especially the ASUS Eee PC line but wanted more power, while maintaining the light and small form factor at the same time. I happened to stumble across the machine upon a recommendation from a friend. I have been using it for about a month now and am extremely pleased. Windows 7 runs very smooth, and almost all of my applications run without problems. I am able to play movies without skipping and ouput them to my HDTV via the HDMI output, which was an important feature for me. The screen is excellent as well.



I have two complaints. The mouse is difficult to use and I am quite prone to accidental "double clicks" while moving the mouse around. I may try to get an external mouse, but this is somewhat annoying. Also, the space bar is quite flimsy and is not always responsive when I type, which is also annoying when typing out lengthy papers for school.

The Spanish zarzuela, that music is a musical drama with dialogue, and may be recognized as paved the way for Christian music, like most of the themes touched beliefs.

Sheet Music Theory - Time Signatures

If you are a new music student, has a few things you must learn first hand, you can read. One of the first questions you will be heard, perhaps, what could be a hit. Most new students of music gives the only answer they have. They say they do not know. Roughly a shock could be a measure of time, but also more and less.

The first thing that determines the definition of a stroke is the timeSignature sheet music that is on the front of a white piece. It is represented by a number placed on each other. One of the most common signatures in time the composition is that the 4 / 4 time. The first thing you need to do is to break the signature of time and find out exactly what it says to you. The upper number four in this special time that you can know that there are four beats in each bar. The lower number is a little 'intimidating for beginners. It may includemost of all can be understood in principle.

One of the reasons why the 4 / 4 is popular with many students is that music is just a number two to understand the failure. In 4 / 4 beats of time is easy with the help of a quarter note for each beat are shown. If you are then other time signatures you'll find that other notes can actually be worth it, but also a shock if you understand the figure below the same signature, you will easily understand theValue of one beat in this particular piece of music paper.

If you sign your time to keep in mind that the lower number is actually a fraction of a whole note. In 4 / 4 time, which means that each note everything can be divided into four parts. One might also ask you, four of which as a note a note everything is the same? "In this case is four quarter notes that equal whole note. Basically what you're looking for is a description that allows you to knowthat each beat is equal to one quarter, and note that there are four crotchet beats in each bar.

Another example could be used as a time 2 / 2 time. After fewer, there would be two, if they split the ticket in this Convention. This is ultimately a note and a half, so any impact would be worthy of a note and a half and there would be two half notes in each bar. There are many other types of time signatures, but you learn as a student of music, manyThis basic technique will help you understand the music when signing basic reading your newspaper. Once you pass the reading of names such as 6 / 8 or even more complex and 12 / 8 you will find that they are not as daunting as you may have thought initially.
