K5IIs versus K5
sportyman - that's a good question.....well I usually don't print larger than 20x30, sometimes 30x45....still since I haven't tried camera without AA filter yet...I wonder - theoretically image from such camera should be able to record slightly more detail, since no blurring occur - in that case if ...

Finally! Pentax K-1 is official... Pre-order and Open Day information
I was comparing SRS prices. I see no reason not to buy it with the K1 body at the bundle price rather than separately. It will come down to similar to the Nikkon 14-24 and I think that will be reasonable as I can't see why the Nikkor could be significantly more expensive to produce that the Tamron...

Finally! Pentax K-1 is official... Pre-order and Open Day information
it looks to me like the k-1 with 15-30 with astro tracer is going to be a great little night sky kit, perfect for shooting landscapes with stars.... is pricy but I'm betting you won't miss having filter threads at night... plus it seems like a nice walk about lens.. I always wanted a WR version of ...

Finally! Pentax K-1 is official... Pre-order and Open Day information
From memory this is (has this been confirmed?) the original Sony A7r sensor, which is over two years old or so now? If it is that sensor then there may be on sensor phase detect AF points. This is the bit I don't understand, as in why a dslr can't have that sort of AF tech as well for live view m...

Pentax K20D
i had the k20 not for long as i use to have the k10 even though the k20 was basicly the k10 with an upgraded sencer i preferd the k10 but it was still better than the k5 Oi I've a K-5 :P I've largely come to the conclusion (after spending a fortune on several hobbies before I got a mortgage) tha...

typical pentax
I really do get extremely bored and irritated with the negativity around Pentax lens options... I use Nikon (D3 and D7100) - one is getting long in the tooth and the other has a pathetic buffer - and I am interested in the D810 and D500...To get the best out of them you need fantastic lenses.......

K-1 Lens Bundle Decision (for mainly low light work)
I defer to John Riley's review so I am putting my experience to my own shortcomings. I have noticed an improvement in using spot focus but not quite the effortless crispness as with the 100mm macro, and I must say the Sigma 150-500 before it was quarantined. My pics were taken with a polarising filt...

Certainly ditch the filter except for situations where you really need it. Filters can affect some lenses quite noticeably.

IR conversion - K100D Super or K7
As I have both the K100D and the K7 lying around and I quite fancy giving IR photography a shot, figured I'd convert either one of the cameras. I can get it done in Poland this summer for 100-120 quid, depending on filter choice; which makes it a rather tempting opportunity. Since I know very li...

IR conversion - K100D Super or K7
Unconverted the K100d works better than the K7, but that's because of it's weak hot mirror. Conversion removes the hot mirror so the K7 would be significantly better. It is possible to focus without the filter on & shift as required for the change in focus. It's not too awkward with many older le...

K70 Rumoured specs online
I know the back story, that Pentax envisaged the K-S line to be different to the K-50 line, but in practise the K-S2 (at least on paper) is everything you would have expected from a K-50 replacement. I think making the K-S2 weather sealed really sealed this for me, as now the two lines are extremel...

Pentax K1 - pulling the trigger
Don't forget the very budget alternative for the wide angle, the FAJ 18-35. It's great value by comparison and does the job! The design is similar to the DAL18-55 and can't see why fitting any filter would be a problem.

Interval composite shooting
Hi all, I am very confused about how to use the 'Interval composite' feature of my K1 (or the K3 previously). My understanding was that one could make a composite image after taking a number of shots and, for instance, would be able to get smooth flowing water without having to use an ND filter. Th...

K10D for IR?
Hi all I appreciate IR conversions have been touched upon in other posts, but I've a couple of specific questions I'd appreciate any thoughts on. I have an old K10D in pretty sorry state after my wife went a*** over t** in Brecon whilst carrying it round her neck a few years ago. Luckily, t...

K10D for IR?
The metering is complicated by the fact that the amount of IR light varies and, as you say, the meter measures visible wavelengths by and large. Live View would be helpful. The technique is to meter without the IR filer, then fit the filter and adjust for the IR focusing mark and simply adjust th...

K10D for IR?
Hi Mattie, that's a pretty good use to put it to. I'm afraid I can't really help with the metering question, as I shoot manual and at this stage I can pretty well get it close enough and if not it's easy enough to tweak after looking at preview, as you would be mostly shooting landscapes this shou...

K10D for IR?
Great, many thanks John and Derek both - I'll look to get a screw-in IR filter and give it a go! Some great images there Derek, btw. I've only got older K series 50mm lenses but I'll be shooting full manual, so can easily manually stop down - I might keep an eye for an a-series 28mm in the upcom...

K10D for IR?
If you are using the older lenses the best resulst i got were generally iso 400 max and adjust shutter speed as needed so it was usually between 30-60 second exp times. I have a hoya R72 72mm IR filter here I have taped a 49 mm ring to the back so it can be used with lens with 49 mm thread. Or if...

K10D for IR?
@ petrochemist are there advantages in using a mirrorless camera for conversion? Yes, several. With a filter fitted to the lens the viewfinder still shows the scene - my camera is full spectrum converted, so I usually have a filter fitted many of which you can't see through. AF works from the...
