how make IR photos with Pentax DSLRs
I was always of the belief that the in-built IR filter in a DSLR "opened up" the sensor's sensitivity range to allow it to "detect" IR wavelengths, and incorporate this additional information into the picture. Maybe I've got it wrong, or I haven't really explained it properly. I suppose the best ...

how make IR photos with Pentax DSLRs
Some cameras will allow enough IR through to make use of an R72 filter possible, some won't. The *istDS was quite good, the K10D less so. Using Photoshop to create a "presudo IR" images can be OK, but it doesn't get the ethereal whiteness of IR film, or the grain, unless you add it. Gaussian mono...

how make IR photos with Pentax DSLRs
Most IR shots from dSLR's you can mimic rather well in post these days. To get a more realistic effect you have to go a step just adding a filter on the lens. Now I just wish there was any dSLR's out there with 10 mp or higher that could handle up to 5000 nm, then moding a dSLR would become us...

how make IR photos with Pentax DSLRs
You cant beat a full spectrum conversion and a bag of filters . Ive got a converted bridge camera as apposed to a dslr so i dont need to worry about AF shift . This one done using an 850nm filter. heres another using R72 and colour channel swapping done

K7 to K5II - features removed or can I just not find them?
2) It is still there :- a) display a photo b) press the 'flash' button on the 4 way controller c) move to the icon on the left of bottom line of the icons displayed d) compare as per the K7 It's best to download and read the K5IIs manual from cover to cover (and repeat every now and again) ...

K5 II - £100 Extra part-exchange!
Chris, What's the best deal on K-5 Mk 11s with 18 - 135mm lens, spare battery and wasiba charger kit, UV lens filter. I would also need shipment to CYPRUS Tom

Anyone gone from K-5 to K-5II?
I might be tempted in a K5 11s, but am I right in thinking that without the anti alisaing filter it resolves better detail but can show more purple fringing ? Cheers Chris

Anyone gone from K-5 to K-5II?
I went from a K-5 to a K-5IIs and don’t regret it. The low light AF is much better – which in my case was, I think, reason enough to upgrade. I haven’t so far seen any big difference due to the missing AA filter (good or bad), but I think you would only really see a difference in a small percentage ...

How I arrived at my IIs
If you'd like me help out in anyway John just ask Mate. I've tried to get it to show moiré and so far I've only had one instance, but I think pixel peeping at over 400% doesn't really count does it :) My next test for it is some macro work to see what detail it can really resolve. One thing I ...

How are 'you' getting on with the K-5 IIs?
We're talking about a filter (over the sensor) - its purpose until very recently was to compensate for certain deficiencies in sensor technology, more so for smaller units I understand. If technology has now advanced to the point that the filter is no longer required, how can that be anything other ...

How are 'you' getting on with the K-5 IIs?
Developments such as removing the aliasing filter (and other changes consequent upon that) are highly unlikely to produce more than a marginal improvement in IQ. Even so, that slim margin may be worth having in some circumstances. Reviews of the Nikon D800E make it apparent that the real benefits ...

How are 'you' getting on with the K-5 IIs?
Wouldn't you expect the Nikon D800E to show the advantages of removing the anti-aliasing filter even more clearly -- because of the larger sensor -- than the Pentax K5IIs? Unless Pentax engineers have outperformed by some way their counterparts at Nikon. Yet Ken Rockwell (see http://kenrockwel...

How are 'you' getting on with the K-5 IIs?
I'm thinking the 's' version would not have any difference in AF performance above the standard K5II ? Under normal shooting (ie using optical viewfinder) on an SLR, ASAIK the AF sensor gets its light via the pentaprism / mirror directly, it doesn't depend on the sensor. Of course, this may be d...

K-5II vs K-5IIs
The K-5IIs lacks the anti-aliasing filter which might cause some daylight lit shots (landscapes) to suffer from moire fringing. The removal of this filter is aimed at benefiting portrait photographers. From what users have written here, there seems to be very little difference in IQ between the t...

K-5II vs K-5IIs
The removal of this filter is aimed at benefiting portrait photographers. The removal of the AA filter will result in increased/sharper definition of detail, so not really for portrait photographers. I'm sure most people don't want to see every pore and defect delineated with crisp, cruel definition...

K-5II vs K-5IIs
The latest models of the K5 are good cameras. They have an improved low-light focusing ability compared to the original K5, so if you do a lot of low-light shooting you might appreciate that. I have not found the K5 deficient in that respect on a day-to-day basis; it depends how much low-light stu...
