Thanks Joostdh,

I've a mix of FF and crop glass so, my sigma 17/70 walk about lens is a very well used and bettered ( dropped, but still works ) so I can see that being replaced at some time. What's your opinion on the focussing speed, better than your crop bodies or same ?

I don't have a problem with its size, it'll be smaller then the 645

I shot a lot of images with the K-1 and 150-450mm at Exmoor Zoo and I was very pleased with the speed and accuracy of the focusing. Significantly better than my K-5.

There was no juddering to lock on, no hunting through the whole range as can happen with the earlier bodies and particularly the 55-300mm lens.

Incidentally, don't overlook the SMC Pentax-FA J 75-300mm lens, still available from SRS at a miniscule £119. This is full frame, dates from the release of the *ist film SLR, but is very good for the price. It's light and effective, not quite as sharp as the 55-300mm but stopped down it takes close inspection to be sure. Not the quietest lens, it wallops into sharp focus on the K-1, but it's light, so gets away with somewhat vigorous operation. I can now add it to my list of lenses I've had, sold, regretted selling and then bought again.....
Best regards, John

Thanks John,

I was trying to shoot some Red Kites at the weekend, and with the Sigma 150 - 500 it did hunt a bit, going up the Mach Loop again in a few weeks and whilst the K5iis has produced some excellent stuff, that tad more focussing accuracy and speed will be most useful. The Sigma 70 - 200 was also good for the jets but need that extra bit of reach at the top of the hill.

I think I'm pretty much decided to go for a K1 next week

Regarding AF speed: that’s hard. I would say it feels a tad speedier and more assured but I realise that is purely subjective. I think the camera as a whole seems more confident.

As for AF accuracy I think that is always a combination of camera and lens. You have a lot of Sigmas which I have had less experience with but the Sigmas I had were always a bit hit or miss for me on crop.

If I look at a classic screw driven lens like the FA43 which I have used quite a lot so far: its accuracy has been really good. At first I though it might be about equal but if I consider the shallower DOF but not more rejects (if anything less) then I must conclude the AF system has to be better. And of course: when the AF is spot on with a sharp lens then the amount of detail you capture is so much more.

I read you”ve made up your mind. I’m sure you won’t be disappointed. I forgot to mention the incredible amount of extra dynamic range with the K-1. You get a lot more exposure leeway.

Thanks Joostdh

Appreciate your post, its one of those things where after looking at all the reviews, taking into account comments from PU where the camera's been used a fair bit now, its several months since its release where you have to take a leap and go for it or stay with what you have and accept the limitations.

What I'm likely to do is downgrade the K5iis to the misses, she shoots as well, but not to the extent I do and have the K5 she uses converted to IR, its not worth much on the market and I fancy some IR stuff having seen what a fellow photographer has produced that I shoot when we've been working together.

I'll probably take the K1 and K5iis to the Machloop and shoot with both the Sigma 70 - 200 and 150 - 500 on both as a non technical comparison and I've the 100 - 300 F4 to play with as well.

Don’t forget those Sigmas might need their mount replaced. I still haven’t found out if they do it no questions asked or if you need proof of purchase, etc. Back to your lenses: both the 70-200 and 150-500 are on the list.

No problem, in hand and being sorted next week,

I spoke to an excellent technician in their Service dept, he's put aside the mounts for me and I'm delivering them on Monday. They've not asked for Proof of Purchase ready for a shoot next week and the Machloop the week after.

Nice, good to hear how well Sigma is handeling this. It seems they are trying to make it as painless as possible.

Personally I would think hard about chopping in all 3 for the 150-450mm.

I rarely use my 70-200mm/100-300mm on the K-5IIs now and I sold the 50-500mm OS to buy the Pentax lens.

Would there have been even the slightest chance that it would have been a no?

I'm a little confused at your OP Chris. I see that you use a 654Z and then asked other their opinion on the performance of two very different cameras.

Am I reading this wrong, as from what I've seen of your work you don't come across as some one who needs input from others as far as selecting camera kit.

Best regards
I could't put it better way ..

I have upgraded progressively

1. K7 to the K5 IIs
2. K5 IIs to K3
3. K3 to K3II
4. and now K1;

I am a little pedantic about evaluating the claimed advantages but only two of those upgrades steps brought tangible advantages to the fore that justified them and as I still have the K3, K3IIs and the new K1I would say that there was definitely a tangible difference between the K3 and the K3II and it is really about focus and the usefulness of Pixel Shit two aspects I didn't expect.

The K1 is a natural process of evolution as far as I am concerned but I think it needs the new lenses and then the question comes as to whether it is in fact these superb the lenses that give this feeling of enhanced performance in the field when using FF or the camera.

However I don't feel that my performance on BIF is enhanced by the K1as compared to the K3IIs, in terms of getting more sharp shots of "high speed flyers " but I do think:

a) HD 150-450 is an advantage whether on the K3 IIs or the K1; of course the IQ is not going to be conspicuously better lenses .

b) The real advantage comes with the bigger window you are working with in tracking flying birds; it is much better that the cropped version.

In an earlier post today there was a request for advice on how to get more well focussed sharp images of Puffins in flight ;

Last week I was on Skomer Island working with the K3 IIs and the K1(on Puffins) and it was clear that if you compare both cameras with a 300mm DA* mounted, after getting used to the FF field of view, the narrower window of the APS C is quite restrictive and disadvantageous when tracking a puffin at 20 meters distance at around 50mph; it passes through the critical "capture point" in fractions of a second so a burst of several frames on Hi Speed drive mode is all that is possible.

In my experience; Focus tracking will not do it.

It is quite simply like looking at that subject it through a small window when using the K3 IIs vs the "Big Window" of the FF.

My technique on the Puffin in flight is to set focus at the 20 metre distance and pan on the blurred image of the approaching bird, pressing the shutter as it flies "into focus" just before it is at an angle directly in front of me, perpendicular to it's flight path.

Set -Up: Anti-shake off, Focus Hold Off, shutter priority set as 1/2000th (+) at 800 ASA. AF set at9pints and drive set at Hi Speed shooting.

Fact: the HD150-450 resulted in a greater number of sharp shots.

So in summary I don't see to much difference in the K3 IIs and the K1 apart from the bigger field of view

But I do see a different practical performance from both in comparison to the K5IIs and the K3.

So my view is; think carefully whether there is an advantage in FF given the disproportionate cost of the lenses and the shear bulk and remember using a K3 IIs with a 150-450 does not produce images that are in anyway inferior to the K1.

K3 IIs is unequivocally a great buy (if you are not worried about built in flash being chopped) .

K1 is superb when you consider what you get for the money and I love this camera

However, I won't upgrade again until there is a significant technology leap over the K1 and in hind-sight (which I hate) would probably have waited for the second or third generation of FFs.

Upgrading from a K5IIs: my advice would be to go for a K3IIs and gradually convert over to a couple of good FF lenses gradually.

Hope this helps

Regards

I have voted "no" in the poll, but I have done so without having touched the K-1 at all (I am starting to feel a strong influence from Ken Rockwell in my forum activities...). Anyway, I am very happy with my Pentax K-5iis, and I very much appreciate the small size of my DSLR kit. For instance, the K-5iis fitted with the DA15/4, constitutes a very powerful photographic tool within a compact package. There are also many DA and K, M and A series primes that are very small, that can be part of a compact K-5iis kit. I am sure that the K-1 is a superior camera to the K-5iis in most aspects, with compactness is also part of camera performance in a way. Another thing to consider is lenses. The DA 15/4 is a wonderful lens, and right now there is no corresponding Pentax D-FA full frame wide angle prime for the Pentax K-1. The D-FA 15-30/2.8 is a very expensive and heavy beast, and quite different from the DA15/4. As a conclusion, my "no" is based on size and lens selection.

Early days yet but I feel I am seeing improved tone and detail in my K1 shots. This is particularly evident in landscapes/cityscapes. For example this shot I took of Waterloo Bridge between the showers on Monday has good detail although it was taken with the nothing grander than the 28-105 mm lens.

Edit: you will have to take my word for it because re-sizing has destroyed the detail I was trying to show I will try posting it in the gallery to see if it fares any better.

From what I have read, the FPS of the K-1 is a slow 3 frames per second. I think I'll wait and see if there is a successor to the K-3iis.
