Putting my Sigma to work...
I picked up my Sigma 30mm 1.4 Art lens in April 2015 at a photography store than had been in business for ages at their going-out-of-sale. (It was a sad event, but while the staff was awesome, the management definitely had some crabbiness issues... but I digress)...anyway, I saved $150 off the street price of $500, and I walked away with my first prime lens since I purchased my Nikon D7100 a few years ago.
At that time, I didn't know exactly what I would use it for, but primes are of course known for their sharpness, and 30mm (45mm on my APS-C sensor) seemed like a "normal" focal range that could come in handy. (For more technical info, you can check out this Sigma page: 30mm Fixed Focal Lens) Note: This is an entirely independent review - I'm way not on Sigma's payroll, believe me, but I just thought that this year I'd start writing some equipment-related blogs here and there to share my experiences with the gear that I have.
Anyway, I've used the lens off and on since I bought it, but I really took it to town (literally) during my trip to New York last November. I knew that I wanted to do some street photography in the city that is often rated #1 for that particular genre, as well as visiting the Metropolitan Art Museum, where tripods are not allowed.
With a huge 1.4 aperture, I was hoping I could make some shots work in the gorgeous rooms of the Met, as well as trying my best to capture a little of life on the streets. I wasn't disappointed. The lens did great, with sharpness intact when I needed it. It was a little hefty in weight, but with this lens and my walkabout zoom, they were all I needed most days.
In this gallery of shots, you'll see it at work in the clarity of the outside of the Guggenheim museum, in the super low-light work in the jazz club, and all the selective focus/Bokeh background in the shots from the Met. Wow - I love this lens, and hope to add a few other primes to my collection at some point!
