Maximizing the Potential of Medium Format Lenses A Comprehensive Guide - Understanding Medium Format Lens Design
Understanding the design and capabilities of medium format lenses is crucial for maximizing their potential.
Medium format lenses have a larger image circle and different optical considerations compared to their 35mm counterparts.
The crop factor between a 645 medium format and 35mm is approximately 0.62, meaning an 80mm medium format lens delivers a similar field of view to a 49.6mm lens on 35mm.
Medium format film offers higher resolution and larger grains, resulting in smaller grains and superior image quality in an equivalent section of the frame.
New medium format cameras and digital backs are now more accessible, making this format an attractive option for hobbyists and enthusiasts beyond just professional photographers.
Medium format lenses have a larger image circle compared to 35mm lenses, allowing for wider fields of view and reduced distortion.
This design consideration is crucial for achieving high-quality results in landscape and architectural photography.
The crop factor of a 645 medium format camera is approximately 62, meaning a 80mm lens will provide a similar field of view to a 6mm lens on a 35mm camera.
Medium format film typically comes in 120 rolls, with the frame size determining the number of exposures per roll.
For example, a 645 frame fits 16 frames on a single 120 roll, providing more shooting flexibility compared to 35mm film.
The TTArtisan 90mm is an example of an extreme medium format lens, offering a super narrow depth of field and an incredibly low price point, making it an attractive option for budget-conscious photographers.
Medium format lenses excel in infrared photography, as they are clearest in the center and have fewer aberrations towards the edges of the frame, resulting in higher-quality infrared images.
The use of medium format lenses on DSLR cameras allows photographers to capture images through the best part of the lens, the center, leading to improved image quality and reduced edge-to-edge distortion.

Maximizing the Potential of Medium Format Lenses A Comprehensive Guide - Mastering Aperture and Depth of Field
Mastering aperture and depth of field is essential for photographers looking to maximize the potential of their medium format lenses.
Aperture, measured in f-stops, directly impacts the depth of field in an image, with wider apertures creating a shallower depth of field and narrower apertures resulting in a deeper depth of field.
Understanding how to effectively utilize aperture and depth of field allows photographers to capture stunning images with their medium format lenses, whether they are shooting portraits, landscapes, or any other subject.
Depth of field can be dramatically different between medium format and 35mm cameras, even with the same focal length lens.
For example, at 1 meter, a 35mm lens may have a depth of field of just 13 cm, while a medium format lens of the same focal length could have a depth of field of over 80 cm.
The larger image circle of medium format lenses allows for the use of wider apertures without introducing significant vignetting or edge softness, giving photographers more creative flexibility with depth of field.
Aperture settings have a more pronounced effect on depth of field with medium format lenses due to the larger sensor size.
Adjusting the aperture by just one stop can drastically change the depth of focus in the final image.
Medium format cameras often have more manual controls and the ability to preview depth of field through the viewfinder, making it easier for photographers to precisely control and fine-tune their aperture settings.
Depth of field calculators designed for 35mm cameras may not accurately predict the depth of field for medium format lenses, as the crop factor and sensor size differences need to be accounted for.
Specialized medium format depth of field apps and online tools have been developed to help photographers accurately predict and plan the depth of field they will achieve with different medium format lens and aperture combinations.
