Why are Good Mamiya 645 Lenses so Important?

Camera lenses are usually more important even than the camera they are attached to in most cases. So, below are some of the reasons as to why you should definitely invest in the best Mamiya 645 lenses.

More Light

The best Mamiya 645 camera lenses are designed to provide you with the option of allowing more light into your camera. This is because they have a wider maximum aperture. Therefore, if you will be shooting in low light conditions, then these lenses are worth considering.

Besides, the Mamiya 645 lenses feature a multi-coating process that increases light transmission. Also, the coating helps reduce flare while also ensuring crisp, vibrant, and natural colors.

Lightweight and Compact

The best Mamiya lenses, in general, are built to be smaller and lighter. So, if weight and space are a big concern for you, these lenses could just be the right fit. They can fit in your tiny backpack and you won’t even notice that you’re carrying them.

Better Image Quality

All Mamiya lenses are quality controlled at all stages. Generally, they boast less barrel distortion and chromatic aberration thereby resulting in better image quality. What’s more, these types of lenses are capable of offering exceptional contrast and sharpness at different focal lengths. This makes them ideal for professional use.

Cover a Wide Range of Photographic Situations

Another benefit of using the Mamiya 645 lenses is that they are designed for a wide range of subjects. From portraits to wedding photography and landscape, these lenses are built with professional photographers in mind.

Shallow Depth of Field

Last but not least, the best Mamiya 645 lenses boast a shallower depth of field thanks to their wider apertures. This makes them the most suitable lenses for photographers looking to take shots where the background is blurred out.

The Buying Guide

In our view, the first factor one needs to consider is the build quality. You basically want to make sure that you settle for a lens that’s built to last. Its chassis can be metallic or made from high-quality plastic.

The next factor to ponder upon is the size of the aperture. A wide aperture is important for low-light photography or if you don’t have an idea of how to set up a perfect lighting system.

While at it, don’t forget about the focal length. Generally, the 28mm, 35mm, and 50mm are the most popular focal lengths for beginners. Generally, the shorter the focal length the wider the field of view and vice versa.

Most importantly, you want to see to it that the kind of lens you settle for is capable of accommodating your camera model. Luckily for you, all the lenses included above are compatible with the Mamiya 645.

Last but not least, you may want to ponder the budget. Just how much are you ready to spend on your next lens? Generally, you’re likely to get a better deal if you raise your budget a little bit.

Depth of Field

This is simply the focusing range where the subject in question remains sharp. Generally, a wide aperture such as f/1.8 boasts a shallow depth of field. This means that it can easily separate your subject from the background and foreground. Ideally, the smaller the aperture size, the deeper the depth of field. And as a result, you can expect sharper images.

What you want to Photograph

More importantly, you need to think about what you plan to photograph. If you like taking travel or landscape photos, the best Mamiya 645 lenses should allow you to capture a wide view. However, if you prefer shooting events or portraits, Mamiya 645 prime lenses might be the way to go.

Frequently Asked Questions

If you’ve just got yourself a Mamiya 645 camera, below are answers to some of the questions about the best lenses.

What’s the difference between MamiyaSekor C and Mamiya AF lenses?

Generally, the C lenses come with an optical design that comprises at least five elements in four or more groups. AF lenses, on the other hand, lack aperture rings and instead use electronically controlled body-driven apertures.

Can I use manual focus lenses on Mamiya AF bodies?

Yes you can. However, you risk losing auto-aperture which means you have to set it manually.

Which One Is The Best?

The Mamiya 645 AF 45mm f/2.8 lens is in our view, the best pick from this comprehensive list. It has a relatively wide aperture plus its focal length is just perfect for a standard lens. We also like the fact that it’s compact and easy to store.

Final Thoughts

The decision on the best Mamiya 645 lens is entirely yours. That’s because styles of photography vary from one person to the next.

Heading out for some landscape or wildlife documentary shots? A telephoto lens would be a much better choice. Looking for a basic, day-to-day use lens? A standard lens would be your best bet.
