Lenses without autofocus: what can you use them for?

Manual lenses are cheap, but that shouldn’t be your reason for buying them. It’s a conscious decision to opt for limitations – or even to enjoy them.

There’s a second reason why manual lenses can be attractive: they cost less than comparable lenses with autofocus. Manufacturers such as 7artisans, Voigtländer and TTArtisan have discovered a gap in the market here. They offer numerous lenses that don’t require any electronics, thereby making them incredibly affordable.

This also applies to the TTArtisan 50 mm f/1.2. It only costs about 100 francs or euros. This lens is available for all current bayonets, including Canon, Fujifilm, Nikon, Sony, L-Mount and MFT. I tested the Canon version.

The lens is already several years old and you can find loads of reviews of it online. Rather than adding my own to this already long list, I’d rather use the lens to gain experience with this type of photography.

As this is a lens for APS-C sensors, the field of view on a full-frame camera is reduced by a factor of 1.6 – or the corners remain dark. The lens is small despite its high speed. This is partly because of the APS-C format and also because there’s nothing inside except the glass. In other words, no focus motors or image stabiliser.

No electronic data transmission

In addition, the camera doesn’t know which aperture is set. The aperture priority (AV) still works, but the aperture information is missing in the metadata. Manual mode M also works, but P and Tv (or S) don’t. I can take pictures in these modes, but they’re not properly exposed.

Two tools for manual focusing

At the beginning, my photos are rarely sharp. That’s because I can’t see in the viewfinder or on the LCD whether the focus point is exactly in the right place, so I activate focus peaking. The sharp parts of the image are marked in red in the viewfinder. These increase with the depth of field. Yep, this also works without data transfer because the image is analysed.

However, I quickly realise that the red edges are annoying when choosing the field of view. That’s why I use the second tool: the magnifying glass, which shows me the image section enlarged six or fifteen times in two stages. This allows me to focus precisely on a specific point. I then move the section with the mini joystick.

Continuous shooting function increases the probability of success

With an aperture of f/1.2, the depth of field is so shallow that the slightest movement can cause the focus to be off. This affects camera movements, for example when I’m shooting without a tripod and have nothing to use as a support. It also impacts on subject movements, such as a plant moving slightly in the wind in a portrait.

The continuous shooting function helps in these cases. I take about five pictures in a very short time, hoping that one of them will be perfectly sharp at the desired location. However, this produces a large amount of waste and doesn’t guarantee that an image will really be perfectly sharp; it only increases the chance.

Objects at close range: yes, but not with this lens

I had to increase it to f/2 for it to work here. The background is still quiet enough.

Sport and wildlife

For sports, a manual telephoto lens like the TTArtisan 500 mm could be useful. But it wouldn’t be so good for wild animals, except when they’re sleeping.

Video

In certain cases, a manual lens is also useful for videos. Of course, it needs to be a scene where you don’t have to constantly refocus and can choose the speed yourself when focusing. Typically, you use a tripod to help you. As manual lenses have neither a focus motor nor an image stabiliser, they don’t cause any noise that can be heard on the video.

Verdict: don’t buy just because of the price

If, on the other hand, you enjoy slow, static photography, a manual lens is the right one for you. Landscape also works very well if you take your time. Object photography too, as long as you can get close enough with the lens. Funnily enough, even certain sports shots are a hit, even though this certainly isn’t the preserve of manual lenses.

My interest in IT and writing landed me in tech journalism early on (2000). I want to know how we can use technology without being used. Outside of the office, I’m a keen musician who makes up for lacking talent with excessive enthusiasm.
