6- More pictures

The main goal for buying the 60-250mm was to resume wild life photography. Here are some examples of my very first outdoor test :wink: .

Some comments on the images shown before

My first pictures were blurred until I remember that basic rule on photography about distance and speed of the subject, focal length of the lens and speed of the camera.

Using a powerful zoom as the 60-250mm requires fast speed to avoid blurring. In order to avoid depth-of-field difficulties, small apertures (large f number) are welcome : the solution relies then on sensitivity. Pentax offers a unique mode for that purpose : the TAV mode.


First, select the ISO range you want to allow. On my K10D, noise starts at 800, so I selected the 100-400 range.

Image

Then, select the Pentax-exclusive TAV mode : you select the speed and the aperture through the front and rear dials, and the K10D automatically adjusts the sensitivity.

Image

The display shows the three parameters : speed, aperture and sensitivity. Ditto on the view-finder. If one of the parameters blinks, you're out of range.

7- Aperture test

For each picture, I provide the full image and a 400 x 400 top-left 100% crop.

Focal length 60 mm

f/4.0 1/2000s iso100 60.0 mm
Image Image

f/5.6 1/1000s iso100 60.0 mm
Image Image

f/8.0 1/500s iso100 60.0 mm
Image Image

f/11.0 1/250s iso100 60.0 mm
Image Image

f/16.0 1/125s iso100 60.0 mm
Image Image

f/22.0 1/90s iso125 60.0 mm
Image Image

f/32.0 1/90s iso250 60.0 mm
Image Image


Focal length 250 mm

f/4.0 1/2000s iso100 250.0 mm
Image Image

f/5.6 1/1500s iso100 250.0 mm
Image Image

f/8.0 1/750s iso100 250.0 mm
Image Image

f/11.0 1/350s iso100 250.0 mm
Image Image

f/16.0 1/180s iso100 250.0 mm
Image Image

f/22.0 1/180s iso200 250.0 mm
Image Image

f/32.0 1/180s iso400 250.0 mm
Image Image


Conclusion

I can't manage to notice vignetting at 60 mm. At 250 mm, it appears to be the same except with f/4.0.
Maybe better eyes :shock: than mine could identify more :?:

9- Pros and Cons and Wrap-Up

Pros
  • Build high quality
  • Silent and fast AF thanks to SDM
  • Lens and image quality
  • Versatile tilting system for the K10D + 60-250mm when attached to a tripod
Cons
  • Some slight vignetting at 250mm f/4
  • Weight and size
  • Specific handling of the K10D + 60-250mm to mount and remove the lens
  • Redundant range of 60-135 between the 50-135mm and the 60-250mm lenses
Wrap-up
  • With this new lens, we're dealing with truly professional gear. Pentax continues its DA* SDM line of high quality lenses.
  • As always with Pentax, ergonomics and ease of use are great.
  • But this comes at a price, in term of weight and size, which may imply a learning curve to mount and remove the lens, and also a strong bag :).
  • The tripod mount built on the lens with the tilting system offers great ease of use.
  • Pentax could have shift the range from 60-250mm to 100-300mm, more consistent with the actual range of DA*
  • Most important, image quality is here and I had a lot of fun.

I'm confident Gordon and his team are going to test vignetting, chromatic aberration and many more technical parameters, so CameraLabs readers will get a full picture of this new lens :!:

10- Two Questions

Now, two questions, and more than two answers :)

The DA* 16-50mm + DA* 50-135mm + DA* 60-250mm lenses together cover the range of the DA 18-250mm, but obviously not for the same price. The three DA* lenses sum at EUR 2650 (EUR 720 + 830 + 1100) while the single 18-250mm lens stands at EUR 500. That's a 5x difference!

The main answer is built quality and image quality. Also, DA* are dust and water proof. SDM provides silent and fast focus.


What is the legitimacy of the DA* f/2.8 50-135mm lens versus the DA* f/4 60-250mm lens? Is it worth the purchase?

I discovered it wasn't a problem beause each lens is dedicated to a special usage :
  • the DA* 16-50mm f/2.8 is perfect for landscape and architecture
  • the DA* f/2.8 50-135mm is highly suitable for family events and in-door photography
  • the DA* f/4 60-250mm lens is more convinient for wild-life photography, with a large zoom possibility. But the f/4 instead of the f/2.8 aperture makes it less versatile for in-door photography.

The gap between 50mm and 60mm is not that much, so picking two out of three gives the DA* 16-50mm and DA* 60-250mm.

More important of all, have fun and enjoy photography :)

White duck

f/4.0 1/1500s iso280 250.0 mm
Image

Image

Maybe some purple fringing on the left, but I'm not sure whether it comes from the lens, from the K10D sensor of from the JPEG conversion.

Image

The details and the white nuances are incredible :)

Duck river landing

This is a first attempt to shoot a duck landing in a river. Autofocus was set on continuous and central spot, as well as shooting mode on continuous. Shake reduction was off.

All pictures are un-processed. Some pictures are blurry, the duck was pretty fast and the central spot focused on the water. But you get the idea :!:

Help is welcomed to improve my shooting :)

rei_vilo,

That "continuos focus" about drove me nuts!!!
I now shoot in AF.S (Single mode)
The shot you tried with the duck is about the hardest one there is with it coming straight twds you.
That takes alot of practice and some luck to nail,or maybe some practice and alotta luck :wink:
It's tough to get the cam/focus to grab the duck but...it will.
I think alot of cameras/lenses would have a hard time to keep up at that speed.

Might bump your ISO to 400 on a sunny day :wink:

Bonjour kpr,

Thank you for the advice :) I'll try again...

Obviously, such a shot can't be done in auto mode :!: So welcome to the wonderful -and difficult- world of manual settings: that's the very reason I bought the K10D for.

ISO 400 is ok with little noise for my K10D.

Wildlife Pictures

The main purpose of the DA* 60-250mm was shooting wildlife pictures.

Here are some pictures. Enjoy :)

ISO200, 1/180, f/5.6, 250mm
Image

ISO100, 1/1000, F/32, 250mm
Image

ISO400, 1/750, f/4, 250mm
Image

I haven't realized before how difficult is to shoot a bird flying, especially when the wind is blowing :!: I tried first the continuous auto-focus with central point focus, then went back to self-select point green mode auto-focus. The birds were 10 to 20m away (3 to 6 feet) so auto-focus was needed.

Bonjour,

See how this lens performs on bokeh compared with other DA* lenses.

Please check my :arrow: Pentax DA* Lenses Bokeh User Review.

Bonjour,

I'm still very happy with my Lowepro Rezo 190 AW camera bag: it carries all my gear safely.

But it isn't exactly the best when going out-door, especially with the DA* 60-250 f/4 SDM tele-zoom. So I went for the Lowepro Micro Trekker 200.

Image Image

Check my :arrow: User Review on Camera Labs or the :arrow: full review with more pictures on my website.

Enjoy :)

Just a quick note about my website.

I closed all the accounts linked with Google, including webiste, mail, pictures, videos, ...

I've launched a new website about photography, available :arrow: here.

The content is currently being transferred to the new website.

See you there ;)
