Best Prime Lens for Portraits

 

1. Pentax DA 50mm f/1.8

Pentax DA 50mm f/1.8 has rounded diaphragm blades that create a more circular aperture, which yields beautiful bokeh at large apertures.

Unfortunately, there is no quick shift focus system for instant switching from auto to manual focus.

However:

I liked the super protect coating that repels dust, water, and grease from the lens surface. 

This prime lens for Pentax K-70 is exceptionally sharp around f/2.5 to an f/3.5. When I opened the lens at maximum width, I could notice slight vignetting in the corners, but it was not an issue, especially on stationary objects.

Although there was a slight vignetting, I must stress that the lens consistently produced sharp images of the same quality throughout the testing. 

The lens belongs to a lightweight category due to plastic built.

On the other hand, although it is plastic, the quality is rock-solid, and it feels useful in hands.

This lens works great for portraits, but with enough creativity, this can be used for all sorts of things.

Pros

  • Outstanding image quality
  • Build quality
  • All-weather sealed

Cons

  • Chromatic aberration at maximum aperture

Best Wide-Angle Lens for Landscapes

 

2. Pentax 15-30mm f/2.8

Pentax D FA 15-30mm f/2.8 ED SDM WR is a lens with a supersonic direct-drive motor, responsible for smooth and accurate autofocus operations while remaining quiet.

The lens has a minimum focus distance of 28 cm, so you can be assured it will be convenient to capture subjects with a well-defined sense of depth. 

Since the lens is designed with eight seals, it will be safe to take it in the rain; the seals work well in repelling the water and preventing it from getting inside.

The image quality of this wide-angle lens for Pentax K-70 is outstanding. During the shooting in clear weather, all of the pictures came out with nicely saturated colors and much-preserved details.

In the more challenging environments, an f/2.8 comes in handy, especially if you decide to shoot from hands. 

The slight distortion at 15 mm is present, but it won’t mind if you are not a pixel peeper. Either way, it disappears entirely at 30 mm.

The only downside is the weight of this lens, which is not negligible.

However, for an ultra-wide-angle performance, it is one flaw I didn’t mind too much.

Pros

  • Build quality
  • Incredible color rendering
  • Sharp images

Cons

  • Distortion at 15 mm

Best All-Around lens for everyday photography

 

3. Pentax DA 16-85mm

Pentax HD DA 16-85 mm is a weather-resistant lens, ready to operate under challenging conditions, including cold and dusty environments.

Thanks to its Pentax SP coating, the exposed lens element is protected, while the ED glass optical elements offer outstanding performance. The newly implemented layer optimizes light transmission and minimizes reflection.

I found this HD technology to work exceptionally well since I have tested flare resistance, and I was delighted with the outcomes. 

This all-around lens for Pentax K-70 camera is quite sharp and is excellent for casual situations and landscape photography, where the fast aperture is not usually needed. The lens is well built but not heavy despite the size, and the lens hood is designed surprisingly well.

The aperture is sufficient for most situations, but since it is not fast or constant, it would be too much to call it perfect. It tends to get slower, especially towards the long focal length end, which can be tricky in low-light situations. 

The Ultrasonic focusing is high-speed and quiet, and as it’s also weather-sealed when it’s put on one of the weather-sealed Pentax bodies, you have a very versatile rig.

Also:

It is worth to mention there is only a small amount of distortion at all ranges, but she sharpness, color saturation, and detail amount are extraordinarily well balanced. 

Pros

  • Weather-resistant
  • Very sharp
  • Color saturation

Cons

  • Small amount of distortion

Best Telephoto Lens for Wildlife Photography

 

4. Pentax 55-300mm f/4.5-6.3

Pentax HD DA 55-300mm f/4.5-6.3 ED PLM WR RE has nine diaphragm blades and a rear focus system with a pulse motor. Its construction is weather-resistant. Implementation of HD coating has optimized light transmittance and has minimized the reflection.

I liked the feature of a quick shift focus system that instantly changed between auto and manual focusing by twisting the focus ring. 

Every picture I shot with this telephoto lens came out razor-sharp with a gorgeous color rendering. The bokeh effect is mesmerizing as well, and I didn’t expect it from this lens.

Autofocus is very responsive and accurate. When I needed a manual tweaking, I could twist the focus ring and switch to manual. The aperture could be wider, but even an f/4.5 in combination with K-70’s high ISO performance yields incredible results.

The wide zoom range makes this lens extraordinarily useful, and for most of the situations, this is the lens any photographer would keep mounted on the camera.

Considering its focal length that is quite versatile, the lens is not heavy, and it folds up into a very compact package when it is not in use.

Bottom line:

If you are looking for a telephoto lens to improve image quality you get with a Pentax K-70 camera, this is the right lens for you.

Pros

  • Weather-resistant
  • Razor sharp images
  • Amazing bokeh

Cons

  •  Aperture could be wider

Best Macro Lens for Macro Photography

 

5. Pentax 100mm f/2.8

Pentax 100mm f/2.8 WR D FA SMC is a weather-resistant lens with round aperture blades for the emphasis of a background blur.

The lens in matter features a full 1:1 image magnification ratio. I was surprised by this macro lens for Pentax K-70 because it has taken me a while to target my subject and focus out to infinity accurately. 

However:

This only applies if a photographer stands far from the focus point; if one is near the point, the lens locks the focus quite fast.

If this were the action lens, I would object to it, but it is not a deal-breaker for macro and portrait photography. Generally speaking, the lens is fantastic. It is made out of aluminum, and the weather-sealings do a great job.

Since it is relatively compact, it is not difficult to carry it around or shoot without the tripod. The image quality is outstanding. 

All of the pictures came out smoking-sharp all across the frame with virtually no distortion. At an f/2.8, the image quality is excellent, with fine details and well-exposed subjects.

In the low-light conditions, this is the lens that will not disappoint you. I did shooting in the late evening, with almost no external light source, and at an f/2.8, pictures looked shockingly good.

Pros

  • Detailed images
  • Great build focus
  • Bokeh effects

Cons

  • Focusing at night
