When to Upgrade K-X ?
I also would not recommend upgrading the K-x to the K-r. In performance terms they will be almost the same, maybe the K-r is marginally better in low light, but this will be negligible as the sensor in the K-x is already excellent in this regard. I noted your reference to 'focus issues' with the...

When to Upgrade K-X ?
stub - interested to know why you thing a newer model d3200 would be a backward step... I'm not Nikon bashing but the noise levels on the Sony 24mp are well documented as pretty poor - check out the results for cameras using this apsc unit. Also no focus motor in the body, lower fps than the kr ...

K-5 II vs. K-5 IIs - why the price difference?
The images are very different with, and without the AA-filter. Without it the images are actually easy noticable quite a lot sharper. The drawback is of course moiré, and then especially in movie mode. People do forget that they don't just simply remove the low-pass filter from the sensor. Sure...

K-5 II vs. K-5 IIs - why the price difference?
The IIs is definitely the one to get. I have long called for a small sensor camera with no AA filter, given that the 645D and similar don't have them to begin with. It took Nikon to do it, but at least Pentax are copying the right thing!

So is the K5II And K5IIS Worth buying ?
I have hung on for a sensible upgrade to my K-7 and it's been hard not to go for the 5 especially when you see how good it is in low light and high ISO. But resist I have and now, after seeing the demo pictures, I am glad I have done the right thing, I will be opting for the IIs. It won't be until M...

Sample shots from both the K-5 II and IIs. Shame they're not directly comparable.
I'm swaying towards the K-5II (without the 's'). I'm not sure I need 'extreme detail'. Extreme low-light, yes. What I'd like to know is, does removing the AA filter let any more light onto the sensor, and if so, is it significant? (1/3-1/2 a stop more light being significant, less and I don't really...

I find that the green hexagon usually comes on, stays on, then goes off, as I move the focus ring. I think this may be because the focus sensor picks up other objects in it's range. Say if you want focus on the *front* of one particular apple on a tree, there may be other things (twigs, leaves, othe...

One thing you should be aware of when fitting a new focussing screen for accurate manual focussing is that you may also need to fit a new focussing screen "shim" as well. The "shim" is a little washer type thing that ensures that the focussing screen is positioned at the correct distance from the le...

Pentax FF DSLR - confirmed
I wonder who will actually buy a FF Pentax DSLR. I doubt if many professionals will unless Pentax can organise a full professional backup service with fast servicing, lens hire etc. That leaves the enthusiastic amateurs. With recent advances in sensor technology the improvement in image quality i...

Pentax FF DSLR - confirmed
Hmmm. I would hypothetically speaking be interested in a Pentax 2013 model FF camera. I have quite a few lenses that would be well suited to FF, and had in any case decided to do nothing before the new generation of Sony sensors are introduced next year promising a major step up in capabilities. ...

Pentax FF DSLR - confirmed
Shaky, you may have answered my question above about how to tell which DA lens will work on FF - are you saying that all the Limiteds have a full frame image circle? Nope. Strictly speaking the newer ones with 'DA' somewhere in the name are intended for APS C. You might nevertheless find individual...

Surely the 645 is a largely specialist / extreme minority type of item? No doubt image quality is there, but as far as camera features and performance goes then it would not have the versatility of a top end DSLR for Professional work out and about in the world, and presumably not as quick and easy ...

Surely the 645 is a largely specialist / extreme minority type of item?..... So is a FF :shock: I think the Nikon 600 and 800's were somewhere in the 50's in the Japanese top sellers last week. Mind you the Pentax K-30 was in there with them. Precisely. The 600 and 800 are expensive and high end pie...

Surely the 645 is a largely specialist / extreme minority type of item?..... So is a FF :shock: Sure, for now! But the rapid advances in sensor technologies (increased performance + improved value) over time will soon start to take effect in the FF arena as well. Once this has more effect then grad...

K5 IIs images
Sure, that'd be good to know. There's nothing to suggest its not a good quality lens that I can see. The pictures do look to me like ones that would, with a normal sensor, have had some PP sharpening done. So if they had not had this, then that would be showing us the effect of the removed filter on...

Why are you expecting difference in image quality. After Afterall its it's the same sensor. Expect better and quicker focussing, esp low lowlight

K-5ii & K-5iis studio test shots
Why are you expecting difference in image quality. I'm not some people are because of the removal of the AA sensor. The K-5 probably only has a weak AA sensor anyway. It's compacts that have and need a strong AA filter. I usually MF so faster AF isn't a high priority although I would like to s...
