Pentax K-3 Monochrome Conversion
After all these years of simply going to the B/W settings of my many Pentax cameras (including a K-3) when I wanted B/W or of using the computer, your remarks make me wonder what I have been missing or getting wrong. I cannot imagine what. I’m certainly happier now than I was in front of the tons o...

Pentax K-3 Monochrome Conversion
I suspect it's to do with demosaicing which is needed to reconstruct a colour image from a Bayer type colour image sensor. Demosaicing inevitable produces artifacts of edge softening. With monochrome sensors or other unusual colour sensors like what Sigma used in their dslr's demosaicing is not need...

The Pentax K-1…
Both versions share the same sensor and of course the feature set is the same, there was a lot of discussion at launch about how the "improvements" could be detrimental to some low light images (particularly Astro) but I think the general consensus worked out that there were almost no negatives to t...

The Pentax K-1…
This information from dpreview could be useful: Particularly look at this the 'Raw DR: ISO-invariance' image comparison tool, if you select the K1 and the K1 mark ii and look at a dark area say at ISO 640 it's apparent that what should be black looks fine in the K1 but has a purple tint with...

This might be of interest, unfortunately.
Small size, light weight, screen not optical? I'd be very happy with a new Q with built-in EVF as well as screen and with latest generation sensor. And, of course, integrated with social media for the new generations :evil:. Steve

I have invested even in the film days mid 80s, so I won't be leaving Pentax anytime soon and having the privilege of owning a K1ii, till death does us part or which ever comes first.:surprised: K70 as well and still building up my many lenses. I love the fact that I stuck with Pentax, It cost me...

This might be of interest, unfortunately.
It has been over a year since I switched from Pentax to a mirrorless system so I thought you might like me to share my thoughts, like everyone here I enjoyed the results from my K1 and assorted lenses but a few things started giving me doubts. Firstly, the weight of some lenses like the 150-450 mean...

Pentax KP
I have for many years been using both digital and film cameras (35mm and medium format). My digital cameras have for many years been the K-5, K-5iis and Ricoh GRii. These cameras all have a 16mp Sony sensor, and in many ways give similar (very good) results. The last few years I have been shooting l...

Pentax KP
I purchased the K70 from new as it was on sale for £350. I wanted the KP but it was just beyond my reach price wise at the time. I researched heavily about both cameras and found the following. The K70 has an excellent crop sensor that was developed independently, but the KP crop sensor was a de...

Pentax KP
I have both the KP and the K1ii. Both are superb cameras but without doubt the full frame sensor on the K1 wins hands down in terms of image quality. The versatility of a full frame raw image is a joy. In fairness the apsc offerings from Pentax are all great performers, particularly the later mode...

K10D in 2025
Thank you for comments. Now I have used it more, I'm making sure to check that the autofocus has locked on - it can hunt far more than I'm used to with the K5. I've also noticed some small dust bugs which will mean a sensor clean at some point. My K20 was the same - the problem seems to have been...

K10D in 2025
Welcome Oldaker and that's a beautiful image with vibrant saturated colour yet not so saturated as to look overcooked or blousy. It perfectly illustrates that an older camera and so called kit lens are just as capable of producing stunning sharp images as any modern cameras - (IMHO of course). As I ...

New to me - CCD Sensor....
I couldn't resist a K100D-Super and lens, DA18-55mm AL, because it was cheap as chips, so I convinced myself it would allow me to see what all this CCD sensor fuss was about - Having missed out on the early days of Digital cameras. Plus I thought it may come in use should I ever need a SDM lens t...

Numbers 3 and 5 show what the CCD is all about. I've seen good results with the Tamron on CCD sensors And your 18-55 looks decent - I have 2 but have not produced anything I like yet. Nice set
