Photo-Wednesday: does a good lens have to be big?

Do you want to buy a full-frame camera, but you are scared away by the offer of expensive, large and heavy lenses? It looks like we will see a series of small and light glasses still in 2019. And not just any, because from Sigma.

Sigma announces small lenses for mirrorless cameras. Finally!

Sigma's general manager, Kazuto Yamaki, praised Dpreview in the fact that Sigma intends to sell a series of lenses designed to work with full-frame mirrorless cameras by the end of 2019.

The key fact is that they are supposed to be lenses designed from scratch, so they will be smaller than the current lenses, which were designed to work with SLRs, but only adapted to cooperation with cameras without mirrors. Sigma initially aims to create glass under the L bay, which is a shareholder. However, it can be assumed with a high probability that the lenses will also go to the bayonets of other systems, including Sony FE, Canon RF and Nikon Z. Sigma would cut off a powerful source of income if she decided to limit herself to creating L-mount lenses that are just crawling and not it is known how it will be adopted on the market.

The service Sony Alpha Rumors adds to this information that, according to leaks, Sigma is working on a series of lenses with brightness in the boundary f / 2.0. This would allow for low mass and a small size of lenses, so it would be an equipment perfectly suited for mirrorless cameras.

We all know that if Sigma wants it, she can. And in the last years, I want to do so. Maybe even too much.

This manufacturer over the last years has created a whole range of excellent full-frame lenses working with SLR and mirrorless cameras. A series of bright prime lenses with f / 1.4 light is almost perfect optically, and in terms of image sharpness, it breaks records that once set up glass several times more expensive.

The problem is that the new Sigmas are huge and really heavy. Let's look at the last few premieres:

  • Sigma 40mm F1.4 DG HSM Art: weight 1.2 kg,
  • Sigma 105mm F1.4 DG HSM Art: weight 1.65 kg,
  • Sigma 135mm F1.8 DG HSM Art: weight 1.13 kg
  • Sigma 85mm F1.4 DG HSM Art: weight 1.13 kg

The bag of a professional photographer equipped with two bodies and four Sigma glass, including the necessary accessories, can exceed the mass - about horror - 10 kg.

Added to this is the fact that the mirrorless lenses - which were supposed to be a lighter SLR alternative - are heavier and larger than their own mirror-like counterparts. All due to the fact that Sigma has adopted lustrzankowe lenses via adapter welded on to them for bezlusterkowce. It sounds strange, but for the producer it was the simplest way to quickly enter the market of mirrorless lenses, which meant a potential doubling of sales.

I am waiting for small lenses. Just give me the brightness of f / 2.o or f / 1.8.

Sony A7 III vs Sony A6300

On my Sony A7 III I really like using the Sony 28 mm f / 2.0 lens. It's a small, light and well made glass with a super-fast autofocus. The lens does what it was created for, and it does not pretend to want to record optical quality records. He does not shout that he is a full-frame lens from the top shelf. In fact, it has the size of APS-C glass, and it is less spectacular.

And yes, this lens has its drawbacks, such as a large vignette and visible distortion, but taking into account the price, size and weight, I completely forgive all the cons. The advantage here is incomparably more. In turn, the brightness f / 2.0 allows for very blurring of the background (sometimes too much, especially when filming), and for the exposure of light f / 2.0 on a modern full frame sensor allows you to maintain a reasonable ISO sensitivity even in the worst conditions.

And you know what? I was following the idea of ​​switching to Sony 24 mm f / 1.4, due to the slightly wider viewing angle and much better light, but I liked the tiny 28 mm Sony very much. This is a very underrated lens, and I am not alone in my opinion. I even know several wedding photographers and photojournalists who use this lens at work and praise it very much.

Yes, the full frame is usually large, heavy and professional. It is time for it to finally become mundane.

An example of a 28 mm f / 2.0 lens is no exception. Sony also offers other, small and light glasses, e.g. 50 mm and 85 mm with a f / 1.8 brightness. The small 35 mm f / 1.8 remains a big shortage, which I am looking forward to.

I am also waiting for a new series of Sigma lenses. I count on the fact that someone on the board will finally realize the fact that the best is not always desirable. We live in a time when full frames can be bought for PLN 3.5 thousand, so even hobby hobbyists buy them. It would be useful if this group of people could buy a set of cheap, somewhat compromising but still good enough lenses.
