Canon EF 40mm f2.8 STM review

Lens Canon EF 40mm f2.8 STM popularly called a pancake. The reason is obvious - it is unusually thin and light. It weighs only 130g, which is in stark contrast to the lens. Sigma 40mm f1.4ART, where the focal length is the same, but the weight is 1200g.

sigma 40 f1.4 art vs canon 40 f2.8 stm

Canon EF 40mm f2.8 STM has a maximum aperture of f2.8, which for fixed lens a little... For similar money you can buy Canon EF 50mm f1.8 STM and get a much stronger background blur. As a portrait lens for a crop, the above lens is much more recommended. In general, I do not recommend the EF 40mm f2.8 STM for crop cameras, it will be boring.

Pancake Canon EF 40mm f2.8 STM covers the full frame (and even Fujifilm GFX Medium Format, as my tests showed), so it's worth using it exactly on full frame cameras... This is a standard focal length lens that conveys perspective as we see the world with our own eyes. Strictly speaking, the standard focal length for a full frame is 43mm (36mm by 24mm sensor diagonal). It is the pancake that is closest to this value.

This lens is convenient for shooting indoor reports. The autofocus speed is average here, it does not catch the stars, but it is enough for anything. The aperture is also average, but it is usually enough for most tasks. But the sharpness is excellent throughout the entire field of the frame, starting from the open aperture. I use this lens as a reference lens in my tests. It easily "resolves" as much as 30MP at Canon rand 45mm on Canon R5.

The main feature of this lens is its incredibly compact size, barely perceptible weight and cost. But at the same time it is optically very good. Despite the fact that I have a ton of other cooler optics, this lens takes its special place of honor.

What's so special about the Canon EF 40mm f2.8 STM?

The nice thing about it is that if you want to be light with your full-frame camera, it's easy and simple to do. Do you have a long shoot, where you need to be on your feet for hours? Here is the solution to the problem - Canon EF 40mm f2.8 STM, which can be used to shoot almost anything using the foot zoom (move your feet closer, farther).

This lens refutes the thesis that a full frame is always a heavy and large camera with a large lens. If you know that this is your main focal length, then for the sake of compactness, you don't need to take a crop camera. The Canon EF 40mm f2.8 STM in combination with a Canon mirrorless camera would be a good choice.

What is the difference between 40mm and 35mm and 50mm?

The difference is subtle. About 50mm I can say that this is a different focal length. With 50mm it is sometimes cramped. Additional 10mm, due to which the pancake is wider, make itself felt. But the 40mm f2.8 pancake doesn't blur the background much. You can get a separation from the background, but there will be no direct tangible bokeh with it. In the same time, fifty dollars are famous for their pleasant bokeh. A lens with a focal length of 35mm will be interesting when looking at models with aperture f1.8-2.0 or f1.4. The difference in aperture ratio under some conditions can be decisive. But these lenses are bulkier and more costly.

If you want a similar effect on a Canon crop DSLR, then you should look towards the Canon EF-S 24mm f2.8 STM. Everything is the same, only for crop cameras.

My video review of the Canon EF 40mm f2.8 STM with sample photos:

Tamron DI SP 70-300mm F4.5-6.3 VC USD II

Inexpensive Tamron DI SP 70-300mm F4.5-6.3 VC USD II telephoto camera - is it worth it?

Tamron DI SP 70-300mm F4.5-6.3 VC USD II Is a very budget lens with good tele-range. 70-300mm are breathtaking focal lengths for outdoor photography. You can discreetly snatch people from the crowd, shoot animals of medium wildness, photograph landscapes with an interesting perspective. So, by themselves, focal points are very useful. And the range from 70mm to 300mm gives more functionality than standard 70-200mm telephoto lenses. But the lens has disadvantages and they are tangible.

By the way, I tested the Tamron 70-300mm F4.5-6.3 on Chinese Canon R5... The camera detected the lens, everything worked. You can see the tests in the video review, which will be released later.


  • Good sharpness only at f8-f10
  • Low micro contrast
  • Boke - nothing remarkable
  • Autofocus disgusting
  • The work of the stub is barely perceptible


  • Inexpensive
  • There are many of them at flea markets
  • Looks great and professional

Sample photos on Tamron DI SP 70-300mm F4.5-6.3 II

Lens from the popular series “on your own money". It costs quite inexpensively and, in principle, corresponds to this price. You can buy it, play around, see if you like these focal lengths. If you haven’t had a telephoto lens before and are wondering whether to buy something in the 70-200mm or 100-400mm region, this lens will do the trick. It will also be of interest to undemanding amateur photographers. They ask for a little money for it, while it is somehow autofocus. You can't shoot the dynamics on it, but it will go for a leisurely shooting. You can buy a manual lens with much more outstanding optical qualities. But it will most likely fix and direct hand trick on TVs - it's still a pleasure.


  • If you have a crop camera, I recommend more in this price segment Canon EF-S 55-250mm f4.5-5.6 STM.
  • If you have a full frame and want more, you will need to increase your budget. For a full frame, good telephoto lenses are: Canon EF 70-200 f4L/f2.8L, EF 100-400 f4.5-5.6L and so on.


fujinon 23mm f2 vs viltrox 23mm f1.4

Fujinon XF 23mm f / 2.0 vs Viltrox AF 23mm f / 1.4 review

23mm cropped - very convenient and popular focal length. This is the 35mm equivalent at full frame. Only depth of field will be greater.

The lens with 23mm is an excellent kit for street photography, reportage photography, and in general a good lens for all occasions. I find a 23mm crop prime lens to be much better than a bulky under-zoom. Sigma 18-35mm f1.8... In fact, 23mm does the same thing, but weighs less and can have a higher aperture.

Therefore, you should take a closer look at the heroes of our review:

fujinon 23mm f2 vs viltrox 23mm f1.4

Fujinon XF 23mm f / 2.0 Key Features

  • Sharp always

My favourite - Viltrox AF 23mm f / 1.4, I constantly shoot my reviews for youtube and I drive streams.

For more details, see my review:

Let me remind you that the Viltrox 23mm f1.4 is now available for Canon EOS Mwhich is cool of course.

I also compared Fujinon 23mm f1.4 vs Viltrox 23mm f1.4 and Fujinon 56 f1.2 versus Viltrox 56 f1.4:

In Ukraine, I recommend this shop to buy Fujifilm lenses.

I also have overview of the entire line of Viltrox 23, 33, 56, 85.
