A review of the Pentax 15-30mm, f/2.8 lens.

Before I go any further, I have to state that I have been loyal to 
the Pentax brand since 1974!
I am therefore not making any comparisons between brands in this 'review'
This is a subjective and experiential posting about
 my recent use of this lens during a trip to KZN..
I have used the K1ii for some time and
 the 40meg images are crisp and sharp.
The focus (pun intended) of the review is the lens...

In all the images, the camera and lens combination remained the same.
The settings vary from image to image.
1/2000s, IS0 100, f/2.8. Tv setting
Lens at 30mm.

In the right-hand side of the image is the Tugela River
And on the right is the Spionkop Dam.

1/100s, ISO200, f/2.8. Tv setting
Lens set at 30mm
Sunrise on a bitterly cold KZN morning.
The Aloe and the trees in the foreground were sharp and in focus.
The tiny white dot is actually the moon!

Long exposure of the night sky in KZN.
14,5 minutes, ISO 100, f/8, Bulb setting
Lens at 18mm
This type of photography has always been 'hit-and-miss' for me.
But with the camera on a tripod and the lens almost fully opened
I was able to achieve consistent results like this image.
The camera was triggered by remote control, 
so as to avoid camera shake.
The trees were lit by the existing security lighting at Spionkop lodge

1/4000s, ISO 100, f/2.8. Tv setting
Lens set at 30mm
Sunset from the deck at Spionkop Lodge.
Being Aloe season currently, they tended to feature in many of my shots. 

1/50s, ISO 800, f/2.8. Tv setting
Lens set at 15mm
I could have made this image lighter,
but I was looking to capture the look and feel of the pub at Spionkop Lodge
This lens weighs in at slightly more than 1kg.
This is the first time that I have used an f/2.8 lens on a DSLR.
Back in 1974, my Spotmatic F had an f/2, 55mm lens as the standard.
This is a solidly constructed lens that focusses quickly and quietly.
Although heavier than most, it felt balanced in my hand
and carrying it for extended periods was not an issue.

1/1600s, ISO 400, f/2.8. Tv setting
Lens set at 25mm
Even close up, the detail is pin-sharp.

1/400s, ISO 400, f/2.8. Tv setting
Lens set at 15mm.
As part of my job, I do a lot of accommodation interiors.
The 15-30mm is the ideal lens for that.
This lens is designed to be used in conjunction
with a full frame camera like the K1 range.
I, therefore, did not have the vignetting issues that
 I previously had with my non-compatible 10-20mm lens.
The edges of the image are not distorted and therefore cropping can be kept to a minimum.

Lens set at 15mm
To truly show what the combination can do.
Sharp and clear from corner to corner.

This is a camera body that begs to be taken seriously!
Most DSLR bodies weight around 769gm, 
this beast is just more than 1kg, giving it a very solid feel.

Long exposure.
2 minutes, ISO 100, f/8. Bulb setting
Lens set at 15mm.
This was shot in the early morning and at a shorter time than the star trails
in order to get the stars to stay stationary.

Overall this combination exceeded my expectations as far as
 a wide angle lens on a full frame body is concerned.
In my next review, I will be trying the lens on a K3ii as a comparison.
