Although the format is most closely associated with cheaply produced, low-cost cameras, [[Canon (company)|Canon]], [[Minolta]], [[Minox]], [[Pentax]], [[Rollei]], [[Voigtländer]], and others, as well as Kodak, offered sophisticated, expensive 110 cameras, with excellent multi-element focusing lenses and precise, electronically controlled exposure systems. Such cameras are capable of making high-quality images on 110 film. Some of these cameras are quite small and still hold appeal to [[subminiature photography|subminiature-photography]] enthusiasts.

The small [[negative (photography)|negative]] size of 110 film makes it difficult to enlarge successfully. For these reasons, the 110 format is associated with prints that are often rather grainy and unsharp. This has led to the misconception that the cartridge itself is incapable of holding film flat enough for making high-quality negatives.

The 110 cartridge, as specified by Kodak, has a plastic tab on one end. Camera designers had the option of using this tab to sense film speed, enabling sophisticated cameras to switch between high- and low-speed film. A short tab indicated high-speed film, and a long tab indicated low-speed film. Kodak left it to the film manufacturer to decide which film speeds were high or low. Only a few cameras took advantage of this feature: [[Rollei A110]], [[Canon 110 ED 20]], [[Minolta 110 Zoom SLR]] Mark I/[[Minolta 110 Zoom SLR Mark II|II]], [[Minox 110S]], [[Voigtlander Vitoret 110 EL]], [[Pentax Auto 110]] and the [[Kodak Ektralite 10]].

Some manufacturers would vary the low speed ASA setting and then change it in later models. For example, Minox 110S low speed was 64 ASA (Kodachrome then being made for 110) and high 400 ASA: but Canon 110 ED has 80 ASA only, with the 110 ED 20 having 80 and 400 ASA. <ref>Instructional Manuals: Canon 110 and Minox 110S</ref>

The last 110 film that Kodak produced was ISO 400 speed packed in a cartridge that senses as "low" speed.<ref>{{cite web|url=http://frugalphotographer.store/cat110.php|title=110 Pocket Instamatic film in the Frugal Photographer catalog|website=Frugalphotographer.store|access-date=18 May 2018}}</ref> As shown in the photograph to the right, these cartridges can be modified by hand so that they signal the proper speed to the camera.
