Snail Racing - Review of an Old Lens

by

I decided to post some pictures from a Sigma Macro lens for Canon mount that I purchased off of Ebay. Something that I enjoy about the Sony camera system (A6300,A7R,A7RII) is that they made it so easy to use just about any lens on this camera.  Of course, your mileage can vary but it is good be able to use some old glass on a new camera.  Something that I think both Nikon and Canon have failed at, Canon more so.  The Sigma 50MM F2.8 Macro lens.  I dont have much history about this lens other than it was cheap off of Ebay and my copy seems to be in good condition.  

Snail Racing

I took a series of photos using a makeshift lightbox.  All the parts from the lightbox came from a nearby Fred Meyers which I built for around 20 dollars in materials.  Please note this was my first real stab at macro photography.  The Sigma 50MM F2.8 manual focus lens seems to do a pretty good job.  If you are really into pixel peeping, I would say this is not the sharpest lens, but still very functional.

Snail Racing Depth of Field

The Sigma 50MM F2.8 Macro lens like most macro lens have a pretty shallow depth of field.  Even stopped down to f/16, the depth of field is less than an inch.  As you can see from this photo, the shell fades off in the distance.

Snail Wrestling

Here is the entire cast of snails.  As you can see this is a bit of a challenging shot.  But I managed to get all the snails mostly in the shallow depth of field.
