Canon EF 50mm f/1.8 II

Review Date: Apr 29, 2010 Recommend? yes | Price paid: $85.00 | Rating: 9 

Pros: Extremely sharp and cheap; value for money;
Autofocus is very noisy; manual focus ring is not very practical;

Except for the optics (which is thankfully made of glass), every thing in this lens is plastic, even the mount. But no matter how cheap it may look and feel, the end results are mind blowing. Suitable for portrait and general purpose photography on a 35mm body, this lens can put others in its class to shame.

Few close shots I took on a cropped sensor Canon body 40D


Sigma 17-70mm F2.8-4.5 DC MACRO

Review Date: Feb 2, 2009 Recommend? yes | Price paid: $425.00 | Rating: 8 

Pros: Excellent starter Lens; Price; Construction Quality; Above average image quality
Noisy Focusing, no HSM;

This was my first lens about 2 years back for my Canon XTi, but I only used it for a year and sold it off for a further upgrade. Although a very good starter lens for someone on a tight budget, but even a serious hobbyist wonít hold on to it for very long.
Overall the image quality is reasonably good with very sharp in the center to getting softer as you move away from the center. Well built with focal range offering a wide variety of photographic capabilities.

Macro results are ok, but frankly speaking, nothing beats primes in macro photography.

Since this model did not support HSM (Hyper-Sonic Motor), the focusing is quite noisy with sudden movements in the focusing ring outside. You need to be sure your fingers are not on top of the ring. Iíve heard Sigma has now recently launched an HSM version of this lens.

Would like to share some shots with my Sigma 17-70mm f2.8-4.5 on my Canon XTi:

Canon EF 70-200mm f/4L IS USM

Review Date: Feb 2, 2009 Recommend? yes | Price paid: $1,050.00 | Rating: 10 

Pros: Excellent sharpness; Well built; Very fast auto focus
Tripod collar not supplied; Price

Canon's top of the line lens with outstanding performance, but of course with a hefty price tag.
Excellent sharpness across the entire focal range, with very fast focusing.
Solid bulletproof body design with weather proofing to an extent. The 'IS' really helps when shooting outdoors handheld without a tripod.

The only downside is that 'f4' may not be as fast as its 'f2.8' counterpart in low light conditions or action photography.

Also, in spite of this being an 'L' lens Canon does not supply a tripod collar along with this lens. It has to be purchased separately. Tripod collars can give extreme stability to such kind of lenses when used on a tripod.

Sigma 10-20mm F4-5.6 EX DC HSM

Review Date: Jan 29, 2009 Recommend? yes | Price paid: $500.00 | Rating: 9 

Pros: value for money; well built; fast and quite focus
not very sharp; no weather proofing; not compatible with full frame bodies;

This low priced ultra wide angle zoom lens from sigma is well built and feels solid.

Considered a good travel lens, but I would purely prefer using it for shooting landscapes.

The sweet spot I found was at 16mm-f8, otherwise overall the image quality is a little soft, but when shooting landscapes it is negligible.

If your subjects are too close when shooting at 10mm, then expect a lot of barrel distortion, but I am sure there could be many creative advantages.

Like to share some shots I took from my recently bought Sigma 10-20 f4-5.6 for my Canon XTi.

Happy Shooting!

Sigma 150mm f2.8 APO Macro DG EX HSM

Review Date: Jan 28, 2009 Recommend? yes | Price paid: $640.00 | Rating: 9 

Pros: Sharp results; nice contrast; well built; value for money;

After reading many reviews from various sources, finally I purchased this lens two months back. Trust me, I was not disappointed and it came out to be more that I expected. My first time into macro photography and on a tight budget, I think I made the right choice.

Few shots that I'd like to share shot at life-size (1:1 magnification) taken using the Sigma 150mm f2.8 lens fitted on a Canon 400D/XTi body:

Solid bullet proof body,
Sharp results and nice contrast,
wide aperture of f2.8 really gives control over the DOF with extremely nice bokeh (see sample shot at f2.8

the best deal is that it comes with a tripod collar which is extremely useful.
