1. Pentax 50mm f/1.8

Pentax DA 50mm f/1.8 allows the outstanding depth of field control thanks to its fast aperture. Super protect coating protects the lens’s optical surface, while rounded diaphragm blades create a circular aperture for smoothly defocused backgrounds.

The lens in matter offers the best from two worlds; it is lightweight due to plastic manufacture, yet, it does not feel cheap.

The plastic I am mentioning is of the highest quality. Even after some small beatings in the test, the lens didn’t show one sign of damage. Focusing points are utilized in the best possible way, although I like to shoot with a single focus point.

The focus system itself is reasonably fast and accurate, without too much hunting. In terms of sharpness, there is slight softness at an f/1.8, but this prime lens shines out around an f/2.5 to an f/3.5. If you shoot at these apertures, you will consistently get sharp images.

Portrait photography is gorgeous with this lens. All of the images I took with it came out looking sharply with defocused background and smooth blur.

Separations between subjects and the background are incredible, and the large aperture allows one to shoot even under the night sky. The only objection is the lack of a weather-resistance feature.


  • Fast shutter speeds
  • Great contrast
  • Excellent image quality


  • Made from plastic

Best Wide-Angle Lens for Landscapes


2. Pentax 15-30mm f/2.8

Pentax D FA 15-30mm f/2.8 is an ultra-wide lens with an incredible minimum focusing distance of 28 cm. Extra low dispersion glass elements of the lens are responsible for high-resolution pictures with an outstanding edge-to-edge sharpness throughout the entire zoom range.

This wide-angle lens is weather-resistant, and it comes with an SDD motor for quick and accurate motor operations.

I was mostly delighted with the outstanding color rendering this lens produced. Generally, I like nicely saturated images, and this lens delivers just that.

Sharpness is extraordinary as well, as this Pentax lens shines out even at an f/2.8. If you step down further, you can get even sharper images, but the results are negligible and relevant for print purposes.

I highly recommend using a tripod with these optics. The lens is massive, excellent. The design is superior to the competition, and this piece of equipment feels great when I shoot from the hand.

One thing worth mentioning is the silence and precision in which autofocus operates. Most of the time, I had trouble even hearing the focusing motor.

This lens acquires light-speed and precise autofocus that is way ahead of the other lenses from the category.


  • Build quality
  • Incredible color rendering
  • Sharp images


  • Distortion at 15 mm

Best All-Around lens for everyday photography


3. Pentax 18-55mm f/3.5-5.6

Pentax DA 18-55mm f/3.5-5.6 comes with a 3x zoom focal range that allows a wide range of shooting possibilities.

Pentax’s super-protected coating repels dust, water, and grease from the surface, while the original quick-shift focusing system ensures instant switching from autofocus to manual operation.

The lens is reasonably lightweight, despite its size and zooming capabilities.

I also like that the lens hood has a built-in sliding door, so I didn’t have to remove it to use the polarizer.


The front element does not rotate during focus, which is excellent for filter usage. The weather sealing is a big plus for photographers who like to take their gear in the rain.

This all-around lens for Pentax K3 ii provides fast focusing and smooth zooming and focusing rings. I have noticed slight distortion at full width in terms of image quality, but it was an issue that was easy to remove.

I was also delighted with the sharpness quality, which is quite good even at an f/3.5. Also, images come out very saturated with pleasing colors.

If you like to shoot macro, you will enjoy the 1:3 magnification ratio to capture great close-ups. For anyone who needs an all-around lens as a workhorse, this lens is the best pick.


  • Sharpness quality
  • Fast focusing
  • Lightweight


  • Slight distortion at full width

Best Telephoto Lens for Wildlife Photography


4. Pentax 70-200mm f/2.8

Pentax 70-200mm f/2.8 is a telephoto lens with a shake reduction mechanism and all-weather feature.

The matter lens also has a focus range limiter to minimize autofocus operation time by fixing the focus range to one of three sub-ranges.

Due to the lens’s considerable size, a detachable tripod mount comes in handy, and a new integrated lock mechanism secures the lens from falling.

The contrast and color rendering are both incredible with this lens. The colors are vivid and genuinely pop out if you are shooting under the right lighting conditions. Sharpness is a story of its own with this telephoto lens.

All of the images came out looking incredibly sharp, and the chromatic aberration is almost nonexistent. Pictures appear sharp all across the frame with minor vignetting, visible only if you use the Pentax 1.4x teleconverter.

The focal range is quite versatile, and I could shoot far away objects with ease, without compromising the image quality.

The only downside of this telephoto lens is the lack of image stabilization, but since the shake reduction mechanism does a beautiful job, it is not a deal-breaker.


  • High contrast
  • Good build quality
  • Consistently high sharpness


  • Considerable weight

Best Macro Lens for Macro Photography

 Pentax 100mm f2.8

5. Pentax 100mm f/2.8

Pentax 100mm f/2.8 macro lens has a maximum 1:1 image magnification ratio and a super protect coating for the front element.

The lens is weather-resistant and perfect to use in challenging environments. I like the quick-shift manual focus that helps when shooting moving objects, but the autofocus tends to be slow in fast-paced conditions.

The picture quality, however, is excellent. All of the images that come out with this macro lens for Pentax K3 ii are stunning to point beyond words. It is easy to notice a myriad of fine details and maximally preserved image sharpness.

At an f/2.8, I was able to get decent results in low light situations, but most of the time, when shooting in the dark, I recommend having an artificial source of light or a flash.

The lens construction is incredible; the body is water-resistant, and the metal makes most of the material used. It feels rock-solid and does great even if you mishandle it a bit.

The lens in the matter is a go-to lens when you want to take pictures of reasonably close things. If you are looking for a reliable macro lens that is not too expensive, this Pentax is a preferable outcome.


  • Detailed images
  • Great build focus
  • Bokeh effects


  • Focusing at night
