Hello Pentaxero or Pentaxera , today I have come to tell you about the objectives of Pentax that will change your life as a photographer. Yes, I am not exaggerating, the one who already has one will agree with me, and the one who does not will end up agreeing with me;).

I know that many times when we start it seems to us that getting out of the kit’s objective is a company reserved only for those who master SLR photography but, in my opinion, there is nothing more wrong.

Because you can have great optics being an amateur. You just have to dare with it, want to go that extra step, dare to do without the zoom or prepare to get wonderful bokeh, unfocused backgrounds, or a sharpness that our kit lens cannot always offer.


As we know that it is a subject that usually brings us upside down, Mario made a very complete guide to guide you when buying objectives .

I only give you a brief summary to keep in mind:

  • Brightness: The lower the aperture value indicated on the lens, the brighter. For example, an f / 1.4 is brighter than an f / 5.6.
  • Focal length: is the width of the visual field or scene portion. The more the focal length , the less field of vision (the closer we get), and the less the focal length, the more angle or field of vision (the more we move away (among other things)).
  • Fixed vs Zoom optics : both types have advantages and disadvantages;).
  • Diaphragm Blades: The more, the smoother and more rounded the Bokeh.
  • Sealing and Construction Material: A lens with a plastic mount without sealing to dust or water is not the same as a well-sealed, metal construction lens.
  • Image Stabilizer.
  • Etc.


I can’t think of a better fixed focus Pentax lens than this 50mm f / 1.8 , which Mario named the prince of lenses .

Its openness and light are wonderful. It will allow you to work clearly in low light situations or blur the background in a fascinating way.

It has hardly any distortions, it is compact, light, it is well built and it is a very versatile optics. Not to mention the price. If you haven’t dared with a fixed lens yet, this is a great way to get it right.

2. 35MM F / 2.4 FIXED LENS

If you are looking for a little more angle in your photos, this 35mm f / 2.4 is your ideal Pentax lens. Like the 50mm, it is a very versatile lens for many types of photography such as landscapes and especially events of all kinds.

Not only is the angle ideal, so is its Bokeh and blur. In short, another great investment if you think of a very good optics at a reasonable price.

If you doubt between a 50mm or a 35mm I recommend that you take a look at this article.


If you like portraits and / or macro photography, this Pentax lens can be more than interesting optics for you. I would not be fooled if I told you that I dream that my next lens is exactly this: 100mm f / 2.8 but in Nikon version;).

It is a lens that will allow you to get closer to your models, be they bichejos , plants, flowers or people;), blurring the background and keeping a good blur and plenty of light.

While the price increases relative to the first two Pentax lenses I’ve presented to you, I think it’s worth having. Especially if you already have a very versatile one like the 35mm or the 50mm.

4. 55-300MM F / 4.5-6.3 ZOOM LENS

If you continue to think that a fixed lens is not your thing or if you are simply looking for a zoom range among the Pentax lenses that allows you versatility and adaptability in most situations, this 55-300mm may be what you are looking for.

It is well built, and with very good finishes. The best in his field. So if you are struck by nature photography, sports (normal or extreme) , birds, or even moon photography, this lens is a good candidate for you.

5. 18-135MM F / 3.5-5.6 ZOOM LENS

Another optic from the zoom range of Pentax lenses with which you will have a lot of versatility but in the opposite spectrum to the previous one. With this focal range you can shoot from landscapes to portraits. An ideal off-road lens for travel.

It is light, it has a good construction, it is sealed, it has a precise and silent AF … It is not bad for the price it has, right ?.


Remember to take into account the conversion factor (or multiplication) of your camera when choosing your lens. If you don’t know what I’m talking about, don’t worry, you have it perfectly explained here;).

But broadly speaking, it is the number by which you have to multiply the focal length of your lens if you do not have a Full Frame camera . Normally this is around x1.5 or x1.6.

This means, for example, that a 50mm focal length, on a camera other than Full Frame, becomes a 75mm (in the case of a camera with a multiplication factor of x1.5).


Since you will surely already have a kit lens with a zoom focal range, my personal recommendation is that you dare with a fixed lens. The value for money that the 35mm or 50mm has is amazing.

Do not deny yourself such good goals for fear of not living up to it, believing that everything will be too complicated. Of that nothing, you will see how you catch it on the fly in a short time. You will adore them 😉 and if you already have it covered, dare with a new focal point.

Each new focal length opens up a different world, increases your creativity and your possibilities.

What do you think of these Pentax objectives? Do you (like me) dream of expanding your family? With any in particular? If you want you can explain it to us in comments, we will love to read you 🙂
