Yes, and sensibly they retained the base model number as 5, so it is clearly an 'upgrade option' and wider choice within the same main camera category. If the new models had been released with an entirely new number designation, then that could have been a disappointment and seen as just try-hard m...

infact I find both cameras quite uninteresting That's fine, but don't you find the trend towards having no AA filter interesting? It could prove to be the way for the future and I find that interesting enough in itself. I'm with Mike on this. Sure the removal of the AA filter is 'interesting' but i...

Nothing in these K-5II or K-5IIs to make me upgrade my K-5MkIs either. Not even the '-3ev' AF functioning? That's practically moonlight isn't it? It'll depend on where an individual is coming from and where they need to get to with their shots, and how much money they can easily burn through wit...

Have a look at the comparison review over on the other side... seems like the AF performance is only significant in low light. Still, could be worthwhile for some people. I was wondering, is this higher low light Autofocussing still fully dependant on thE green AF assist lamp, or does the s...

This is the issue that keeps bugging me - there's no response from others so maybe no one knows yet! Could we actually just obtain the same crisp detailing from a 'normal' K5II images by being clever and applying high quality sharpening techniques in software? This would be cheaper if it were true. ...

I'll be upgrading to a regular K5II from my present K5 which is one of the early ones and has seen two years of heavy use. It's already been in for refurb/repair once. I've had too many shots with focus troubles to want to continue with the autofocus on the original K5, if I can avoid it. The other ...

For general use, leaving off the AA filter seems pointless. It isn't left off - it is just a much weaker implementation, you can't leave it out altogether (same applies to the D800E).

K-5IIs At Chester Zoo
It was fairly gloomy in the Rhino House and I was surprised how well the AF locked on (ISO 4000). I think comparing results I got on my previous visit with a K-5 and the same lenses I ended up with more keepers with the K-5IIs. I wouldn’t expect the K-5II to perform any differently – I expect you wi...

K5IIs and PF?
I would imagine it's down to the individual lens to determine the mount of PF, just like the amount of CA I would expect to agree with you, but it appears that the lens, scene and lighting are common, so the only change is the body, the suggestion being that the AA filter seems involved in the produ...

how make IR photos with Pentax DSLRs
I may be wrong but I have a feeling that only the earlier Pentax DSLRs work readily with an IR filter, I have had some success with my *istDS. I think later models need permanent major surgery.

It is possible, but the built-in IR filter is a bit too good. You'll need a long exposure. This was taken with the K-7 through a R72 filter, f/5.6, ISO1600 and 15 sec exposure. It is not really worth the effort just to get tree leaves appear white :). by , on Flickr

this was with K5 and 55-300,hoya r72 filter, custom wb and some channel swapping, all info found on youtube tutorials. not the best perhaps but it is a starting point that i can go back to when the mood takes me

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 ...

I have had good results with the K-x and the Hoya R72. See a few images below: It's not as good as a converted camera, but for £11 for the filter it's not bad! Regards David

how make IR photos with Pentax DSLRs
turned out to be necessary... Yes, it is necessary - it cuts out all visible light and lets only the IR through. ...but not sufficient Just a thought - perhaps you are relying on the metering?? The built in metering will not help at all! You'll probably get a black image if you try ;) For IR ...

Another quick thought - IR taken with the Hoya filter needs some time spent in Post processing to get the best results. I've just had a quick tweak of one of the images posted above to get the levels a bit better: Regards David
