K5 and all those digital filters and effects !
Are they wasted on the majority of users?? I'm still working my way through my new K5 manual and looking forward to the weekend - but I'm suprised at the amount of filter effects etc that have been built into the camera - a camera which, I would guess, most people using it would shoot RAW. ...

K5 and all those digital filters and effects !
you overlooked the previous post where I mention using "In camera raw processing".... my point was it is easier to convert a raw file to jpeg than the other way round which is not possible.... shooting both is ok, but harldy needed and possibly a time waster in post. digital filters is an occasiona...

Kr Review, undeserved bashing???
I must say I read reviews more for the factual content than for the opinions. The more in-depth reviews are useful because they often tell you things the manufacturer's official blub doesn't... provided you learn to extract the useful information and filter out the reviewer's biases. Of course, s...

Sensor cleaning?
Well tonight I did what many would consider a cardinal sin or pure stupidity. I cleaned the "sensor" - by which we all mean the anti-alias filter in front of the sensor, using a cotton bud and some pure methanol. I soaked the cotton bud in methanol then left it 10 minutes to evaporate. I then ...

K-5 number 2 after 1000 shots
I don't think GraphicConverter is a Microsoft product. Here is an example of the ExifTool data, ---- ExifTool ---- ExifTool Version Number : 8.28 ---- System ---- File Name : IMGP5137.PEF Directory : /Users/galoot/Desktop/Pentax_Lates...

K-5 number 2 after 1000 shots
I don't think it's that, Matt... the marks are uncleanable and some clever bods have worked out they are under the AA filter. Pentax stated that some units were shipped with stained sensors, not that the sensor was prone to being sprayed with oil in use. Dunno how the spots appear over time, some...

Help! Sensor cleaning made it worse.
I had exactly the same with my K5 the first time I cleaned it with my arctic butterfly. I think there must be some initial coating over the sensor. A clean with a cleaning swab cleaned it. that's really interesting. some people have noticed k-5 stains developing with time. perhaps some of this initi...

that's really interesting. some people have noticed k-5 stains developing with time. perhaps some of this initial coating you had wiped off might explain it. the coating might sneak in under the AA filter, then cause the stains? I doubt it to be the case. If coating sip between AA and sensor, it sho...

ME Viewfinder Cap (K10D)
Over in the IR thread there is plenty of evidence that the eyepiece stray light can mess up a picture. In that case the reason is the ten-stop difference between the ambient light and the light that comes in through the lens/filter, enough for the tiny amount of light that gets round the mirror...

K-5 Adventures
An afterthought. As we climbed up to Clitheroe Castle, I stopped and looked down at the ampitheatre below. The last time i looked at that scene I was using a Pentax MX with SMC Pentax-M 50mm f1.7 lens, Tri-X, and an orange filter. How's that for memory? :lol:

Filters cheap or expensive?
Ah the age old question of filters, love em or hate em:D I always used to have a UV filter on my lenses then I read a thread on this very forum and now have none at all, other than a couple of cheap CPLs for occasional use. Your going to get lots of advice on this one but at the end of the day...

Filters cheap or expensive?
There is a difference between 'budget' and 'cheap'. You can buy a perfectly good Hoya 77mm UV filter for about £35 and on a normal camera and normal lens it will do a perfectly good job. A B+W will probably cost more like £80 and is probably worth it if your lens is worth £2,000 but not if your l...

FYI I have £60 and £100 lenses so a £10 filter may be about right!

Filters cheap or expensive?
I was interested to read on the comments section of an article titled 5 Kinds of Photography Equipment That Waste Your Money One of which was cheap UV filters. Comments were to the effect that with them your pictures are not so sharp. I have always used fairly budget filters and i need to re...

Filters cheap or expensive?
Having had a camera strap break and send my camera with tamron 80-210 (we're talking sometime ago!) crashing to onto stone paving , I was glad to have had a UV filter on the front which bore the brunt of the impact. It smashed, leaving minimal damage to the lens itself. I am happy to have someth...

I must admit I tend to use UVs as protection, but only against dirt, not mechanical impact. A filter does not absorb any significant impact energy. What it does is stores it then releases it very suddenly and probably fires sharp glass fragments at the lens.
