Sony A57 and the Sigma 50mm f/1.4 EX DG HSM Lens – Real World Sample pics with 100% Crops and First Impressions

Sigma 50mm f/1.4 EX DG HSM Lens

I had the pleasure of shooting some real world photos with the Sigma 50mm f/1.4 EX DG HSM Lens this week as Michele and I are on Vacation!! Oh Yeah ;) Anyway I took some real world sample pics in all different situation and the Sigma performed quite well. Shooting wide open at f/1.4, the Sigma 50mm f/1.4 appears to be sharp and the separation you can get from your subjects is magnificent for an APS-C sized image sensor like the Sony A57 has. The HSM focus is also very fast, accurate, and quiet from what I’ve seen so far. I do notice a significant amount of purple Chromatic Aberrations on ultra high contrast subjects in the center of the frame, but that is very common for this type of lens. In fact the top quality Canon 85mm f/1.4 L Lens does the same thing wide open.

I didn’t use a tri-pod for any of these shots, so the lower shutter speed might be just a tad soft.

I also did not use manual focus at all yet just to let you know.

For this image of Michele and Layla, I switched the Sony A57 to Shutter Priority Mode and dialed it in to 1/25sec. I then tried to catch some motion using a panning method and I managed to get a little bit captured. The ride was going very slow so the panning was harder than normal I must admit!! If your not familer with panning, be sure to check out my Understanding Shutter Speed Tutorial!

Closing remarks

So far I think the lens is really solid for a price tag of $499 US, and I’m really looking forward to doing some “Lab” style tests to check the corner sharpness etc.. These sample pics should give you a pretty good sense of what can be done with this lens, and if you have any requests or questions please just fire away below in the comments.
