K-1 Upgrade thoughts.
A little-advertised fact about the K1 which is mentioned in the brochure is the unique design of the mirror mechanism. In all other DSLR Cameras the mirror simply flips up when the shutter is pressed; as the mirror is scaled up to match the larger sensor this results in a deeper body. However in the...

Your thoughts on UV/Protective filters
... but apparently sensors are receptive to the UV part of the spectrum whereas film isn’t. It's the other way round! The new kids on the block are the clear lens protection filters. UV can be seen at high altitudes so a UV filter should help cut through it and reduce the blueness. Filters aren't...

Your thoughts on UV/Protective filters
I'm an old school film shooter mainly, I always* use a good quality filter of sorts (either UV or Skylight). The only exceptions are medium format lenses that I've bought used that would require huge (80+mm) filters** - these can be more expensive than the lenses! It's not about IQ but protecting th...

It’s gone a bit quiet recently
Don't know about flagship models because personally I will not buy another from Pentax until they totally revamp the autofocus. What I would buy though is a mirrorless in the form of Canon's M5. Having just bought one the only thing that lets the Canon down is lens lineup which is solved with an ...

It’s gone a bit quiet recently
There is absolutely no need to churn out new products every year in order to stay profitable and successful. I think it's more a bad habit we ,as consumers, have developed; constant expectation for stuff we most of the time don't buy anyhow. I'd much rather their time, effort and resources where...

PC advice Needed
I use ccleaner regularly, it’s free with an upgrade to pro level for a modest cost. Never had problems with wiping search history and temporary files, registry cleaning and defragging. Also secure disc wipe should you need that. Pro version is programmable to run in the background.

Shoddy customer service by Ricoh/Pentax
This man Man uses Silkypix and then PS .... https://www.dpreview.com/forums/thread/3984202 -- I do the same. If the photo just needs a raw conversion and cropping i will do this just in Silkypix and process the output as a jpeg. Silkypix does have spotting tools so sensor spots can be cloned out...

K3 shutter repair price
What was your shutter count up to? As he said? And what happened to it; just fall to pieces? Yes, I was getting a black bar over the photos so I locked up the mirror (sensor cleaning) and you can see part of the shutter hanging loose over the sensor :-(

Which Pentax DSLR to upgrade to ?
Moving to a DSLR without an AA filter will probably bring one of the most notable changes (increased sharpness without PP) - if you're after a Used Pentax then the K5iis or K3ii would be a great move - the K3ii having the higher density sensor and the K5iis being a bit older (but still very capable)...

Which Pentax DSLR to upgrade to ?
As comments above...what are your main interests, what is your budget and do you want new or would you buy used? I had the K-x as my first DSLR for over 4 years...loved it but then upgraded to a K-50 almost 3 years ago which i'm still using and have shot about 9000 images with. I valued the weat...

Which Pentax DSLR to upgrade to ?
Any, I went KX, KR, K5 and then both the K3's. i found the K5 a big leap in quality of camera sealing, pentaprism not mirror, quiet shutter, top plate control etc BUT in learning to use more demanding. Buy the best nick one you can. I never had a KX but I did have a KR with the same sensor, and w...

Which Pentax DSLR to upgrade to ?
The effect of a well designed AA filter on an image captured with a Bayer array sensor is not the same as a Gaussian blur. It just happens to be cheaper not to have the filter and rely on the sensor outresolving the lens instead.

XT1200
I still love my K-5iis Gary, In think it's a classic in the line of Pentax crop sensor cameras. These look great, very sharp and defined. Regards David

Renewed Sympathy for the Beginner
Yes, as a lad I was familiar with 35mm camera settings and became adept with a light meter so I thought a dslr would be the same but with a sensor where the film was. How naive! Quite a steep learning curve followed, and still on it. And we had never heard of bokeh then, just out of focus.

Hot weather
It might be a bird or a stray dust bunny to the left of the central steeple, about half way up and a smudge on the sensor to the right of the right hand spire as you look at the image.

Using ext tubes
If you accept that calculation to determine a lenses focal length, then I don't think adding extension tubes makes any difference to the focal length you should dial in. e.g. 1/100 + 1/100 = 2/100 = 1/50 1/150 + 1/50 = 2/100 = 1/50 i.e. if you add to the distance between the lens and the sen...

Go Your Own Way?
By following the clear step-by-step instructions on the Pentax/Ricoh web site, I found that updating the camera firmware was really quite simple, and not nearly as scary as the first time I cleaned the sensor! (I'm happy to report that both procedures have worked perfectly.) Philip

Sorry guys ☹️
No need to apologise. Sony is attracting customers from lots of DSLR companies because the’re innovating and are very competitively priced. This situation is cropping up more and more and the content is usually very similar. People want to stay with Pentax, they really do, but Pentax has not bee...
