Photorama USA offers lenses for digital and film camera systems at in-person shows in Chicago.

You pick up a lens at a Chicago camera show, hold it up to the light, and check the elements for scratches, dust, or fungus. You twist the focus ring to feel how smooth it moves, and you mount it on your own camera body to test autofocus speed and accuracy. The vendor is standing right there, so you can ask about the lens history, whether it has been serviced, and if the previous owner used it professionally or kept it in a bag. Chicago attracts vendors who bring prime lenses, zooms, macro lenses, and specialty optics that do not always show up in online listings.

Photorama USA events feature lenses for Canon, Nikon, Sony, Fujifilm, Pentax, and other mounts. Vendors carry lenses that work with both digital and film systems, and you can inspect optics in person before making a decision. The format allows you to compare a 50mm f/1.8 to a 50mm f/1.4, or test a zoom lens to see if the focal range fits how you shoot. Lenses are commonly bundled with camera bodies, so you can build a complete kit at the same event.

How to Evaluate Lenses at the Show

You arrive at the Chicago show with your camera body and walk from table to table testing lenses on your own equipment. Vendors bring lenses in various conditions, from lightly used trade-ins to older manual focus optics that still produce sharp images. You can check the aperture blades for oil, inspect the lens mount for wear, and test the autofocus motor if the lens has one. Some vendors bring lens caps, hoods, and original boxes, while others sell body-only options at lower prices.

After you purchase a lens, you leave with it in hand and a receipt that confirms the transaction. There is no waiting for shipping or hoping the online description was accurate.

Lenses are useful for photographers expanding their kits or switching to a new focal length. Events attract specialized lens vendors who carry hard-to-find optics like vintage Zeiss glass, fast primes, and telephoto lenses for wildlife or sports photography. The shows serve surrounding regions of each host city, so inventory reflects what photographers in the area are actively buying and selling.

Questions That Come Up Before Buying

Buying a used lens requires checking a few specific things, and knowing what to look for helps you make a confident decision.

What lens mounts and types are available?
Vendors carry lenses for Canon EF, Nikon F, Sony E, Fujifilm X, Pentax K, and other mounts in both autofocus and manual focus designs. You will find prime lenses, zooms, macro lenses, and telephoto options depending on what vendors bring to the show.
How do I check if a lens is in good condition?
Inspect the glass elements for scratches, fungus, haze, or separation. Test the focus ring for smooth movement, check the aperture blades for oil or sticking, and examine the lens mount for wear or damage. If the lens has autofocus, test it on your camera body to confirm it locks accurately.
What should I bring to test lenses at the show?
Bring your camera body so you can mount lenses and test autofocus, exposure, and compatibility. Having your own gear lets you confirm that the lens works with your system and that the focal length fits how you shoot.
Why buy a lens at a show instead of online?
You can inspect the optics, test the lens on your camera, and negotiate directly with the vendor. There is no guessing about condition, and you leave with the lens instead of waiting for shipping.
When is the best time to find specialized lenses?
Arriving early gives you access to the full inventory before high-demand items sell. Specialized lenses like fast primes, vintage glass, and telephoto options tend to move quickly at Chicago shows where photographers know what they are looking for.
