Shuttershock and Olympus 75-300

Since a couple of months I own the Olympus 75-300 III. And since day one, I wasn't happy with the results I got. 
All the pictures shot at +/- 300 mm where soft and looked like there was motion blur. How's that possible? I tried it at a 1/1000th of a second, but still the motion blur in my pictures. I regret that I ever sold my Pentax with the 55-300 for this awfull lens!
But... Most reviews of this lens are positive. Is my copy of this lens bad?
I then figured out by reading forums that it could be a phenomena called 'shuttershock'. It that case, the shock of the shutter causes enough movement so the image is blurred.
For example:

How to fix this?
My camera has several drive modes, including one called 'anti-shock'. And that does magic.
In that mode The pictures are sharp again. No motion blur is visible! 
The downside of this mode is that the fasted drivemode can't be used.

I left Pentax for Olympus

A couple of months ago I didn't feel happy with my camera gear. My DA 16-50 has never been okay and the AF of my Pentax also.

At the time I bought my first Pentax, I didn't wear glasses. Since a couple of years, I really need that kind of protheses ;). Looking through a viewfinder with glasses isn't always easy. Since I could use liveview, that seems to be much easier. Also shooting with my phone was done by "liveview".

Key decision points

I decided I wan't a new camera with the next options:
liveview AF as quick or quicker than my Pentaxsmallbudget friendly good lensesbetter video quality and options My wife owns an Olympus E-PL1 since 2010. That camera has an horrible screen and the autofocus isn't the quickest there is. But...
The size of the camera and also the ease of use is great. Also the 4:3 image ratio is great.
I decided to look for an M43 camera and looked for the Panasonic G80 (G85). I really liked the options and quality, but I didn't like …


This afternoon, I toke a hike of 13k to enjoy the great weather (the first +20 degrees Celsius day of 2017). Because it's spring all animals where active. The birds were singing, the frogs where bussy with the spawn etc etc. 

Enjoy the result:

Pentax pixel shift resolution

Since the Pentax K-3 II, Pentax is using a Pixel shift resolution function. This function uses more info from the sensor by shifting it slightly and taking 4 pictures. How this exactly works can you see in the next video:

But what are the results of using the function?

I shot a picture of some velcro (click for 1:1 resolution):
There are two main differences:
1. no moire 2. much more detail. 
But looking at the full scale there's another difference:

The colors on the pixel shift picture are a little bit more saturated (watch the wooden box in the background)
The next image shows another difference:
There's less noise in the image and the gradiant is smooter (look at the gradiant from white to blue)
This function only applies to static objects and can only be used from a tripod. I tried it handheld, but the result is awfull:

As you can see, the alignment of the pixels is off and I lost resolution in stead of gaining it.

Walk through Meijendel

On oktober 19, I walked around 10 km in Meijendel, a area of dunes around Wassenaar, The Netherlands. Here some photos to give an impression of this wonderful landscape and nature

Comparison between the old and the new 55-300 from Pentax

Last june, Ricoh released a new affordable telezoomlens, The Pentax-DA 1:4.5-6.3 55-300 ED PLM WR RE

This lens is an upgrade from the older 55-300 lens with the screwdrive motor. This is the first lens with a nearly silent motor. This lens is also smaller than it's older brother (in this case, the oldest, non WR version):

The advantage for me is that this lens fits inside my camerabag when attached to my camera and with the hood extended.

The other big advantage is the autofocus. Using the phase detection on my K-3 II the speed is much, much better, but also the hunting is a lot lesser. The difference is like having a picture or not having a picture. I first tested the lens on the beach with some Seagulls:

With the old lens, I wasn't able to get a picture of an flying bird. With this lens, I got around 80% of the pictures in focus. Above pictures where shot with the 9 AF points in the middle.

Also the noise is a bit different:

Are there some disadvantages to the new lens? Yes,…

DXO 10, highlight correction even better

A couple of weeks ago, DXO Labs released version 10 of its image processing software. In earlier post, I complained about the highlight recovery in DXO. Lightroom did a better job and the results where much prettier.

In DXO 10, DXO promises a even better recovery of highlights. So I'd to test that. The results where great! I tested and tested again, and DXO managed to reveal details from my images, I didn't know they where there. See the results by yourselves:

As you can see, DXO is improving each version. Now it beats Lightroom. I easily managed to get all the details from the clouds, without the low contrast of the earlier versions. 

I also tested how much detail I could get from the clouds. The image is looking overdone, but show how much detail can be recovered: Even in the blown out area in the midle of the image (look through the building) has some detail left.
