Use our percentage calculator to work out increases, decreases or percentage differences. Common uses include calculating tax, statistics, savings increases,

As an example, if you want to find what percentage 15 is of 300, you would divide 15 by 300, resulting in 0.05. Multiplying 0.05 by 100 gives you 5%.When you've multiplied the ones digit by every digit in the top number, move to the tens digit in the bottom number. This distortion smoothly transitions to mild pincushion distortion at 50mm with approximately 25mm being the near-distortion-free transition focal length.

I find a lens with this size and weight to be easy to take with you, comfortable to use and to have enough mass to be stable. The relatively small lens hood is large enough to help keep fingers and other objects from touching the front element. The Sigma 17-50 is slightly more expensive than the Tamron 17-50 VC, but the better-optically-performing Tamron 17-50 non-VC is considerably less expensive. Insert a decimal point in the product so it has the same number of decimal places equal to the total from step 1.Multiply as above, but this time write your answers in a new row, shifted one digit place to the left. there is always the possibility that a DSLR body might not support a (likely older) third party lens. Expect a relatively small amount of focus breathing from this lens - the subject/framing changes size a small amount when focusing. The Canon EF-S 17-55 has less barrel distortion at 17mm than the other lenses, but more pincushion distortion at longer focal lengths.

Use long addition to add your number columns from right to left, carrying as you normally do for long addition.Arrange the numbers one on top of the other and line up the place values in columns. The number with the most digits is usually placed on top as the multiplicand. Copper has the unique advantage of oxidizing over time, which means that its color continues to evolve with the life of the sink. The older it gets, the more attractive it looks. Any scratches and flaws that occur on its surface will disappear into the metal as it oxidizes. With an 11" (280mm) MFD and a .2x MM spec, the Sigma 17-50mm f/2.8 EX DC OS HSM Lens is not a strong contender in the close-up competition. At 17mm, I am getting a good rate of sharp images from the Sigma 17-50mm f/2.8 EX DC OS HSM Lens at 1/4 sec exposures for a net 3-stops of assistance from OS.

When multiplying decimals, say, 0.2 0.2 0.2 and 1.25 1.25 1.25, we can begin by forgetting the dots. That means that to find 0.2 × 1.25 0.2 \times 1.25 0.2 × 1.25, we start by finding 2 × 125 2 \times 125 2 × 125, which is 250 250 250. Then we count how many digits to the right of the dots we had in total in the numbers we started with (in this case, it's three: one in 0.2 0.2 0.2 and two in 1.25 1.25 1.25). We then write the dot that many digits from the right in what we obtained. For us, this translates to putting the dot to the left of 2 2 2, which gives 0.250 = 0.25 0.250 = 0.25 0.250 = 0.25 (we write 0 0 0 if we have no number in front of the dot). Long multiplication means you're doing multiplication by hand. The traditional method, or Standard Algorithm, involves multiplying numbers and lining up results according to place value. These are the steps to do long multiplication by hand: I didn't see any significant differentiators from a CA standpoint - these lenses are all similar in this regard. I have not been a big fan of Sigma's matte finish - especially because it readily shows fingerprints and dust.

Our Complete Copper Kitchen Sink Range The Sigma 17-50 OS and the Tamron 17-50 non-VC lenses exhibit the least vignetting with the Canon 17-55 and the Tamron 17-50 VC showing the most. The Sigma 17-50mm f/2.8 EX DC OS HSM Lens indeed turned in better corner performance at a wide open aperture than stopped down one or perhaps even two stops in this test.
