Can you avoid mirror slap during bracking and other issues
Simple is best. Try this: Mount the camera on a tripod. Set to Av and select your aperture of choice. The aperture needs to remain the same otherwise the images DOF will change. Manual focus is also best, to make sure the focus point remains exactly the same. Simply use exposure compensation ...

Can you avoid mirror slap during bracking and other issues
thanks John for coming back to me. I understand the process, but i always create too much movement in the camera fiddling and can see a bit of change in the corners - its probably down to my crap £10 tripod - i assume a good tripod and head locked into place would solve this issue? I am going ...

Noise and intermediate ISO settings
Just read this which I'd not seen before:- "Here is one ISO tip that many photographers aren’t aware of: keep your ISO setting to the industry standard numbers – 100, 200, 400, 800, 1600, 3200, etc. All digital cameras offer ISO settings between these numbers (such as ISO 250). But, what is really ...

Noise and intermediate ISO settings
I've posted this many times before on here, but people just don't seem to read :shock: Goes back to the K10D days at least. If you know YOUR camera you shouldn't need to be told :mrgreen: --

The Front / Back Focus Debate
As mentioned in an earlier thread I have narrowed my lens choice down to two lenses now (at last!) Namely the Tamron 17 50 2.8 and Sigma 10 20 Is it ok to buy a Tamron 17 50 2.8 that might need a little front focusing and adjusting done to it? I imagine it wouldnt be too much of a prob if I toy...

The Front / Back Focus Debate
What body do you have? The Tamron 17-50 does have a front/back focus issue but once adjusted it is fine. The camera remembers the settings for the lens. It goes well with the K-5 and it is very sharp at f5. Wide open is handy for portraits without showing all the creases and spots. It has a...

You'll be fine then, it saves the adjustment. Good value lenses the pair of them :D It would be silly to just buy one, they are complimentary and necessary.

The Front / Back Focus Debate
Advice? There are some excellent wide angle exponents on here, I'm not one of them :D I carried it about a lot but rarely used it. A 77mm CPL polarizing filter is not cheap. And apparently you get weird results at wide angles. Carry a tripod with you, I was using it on a K-7 and needed a b...

The Front / Back Focus Debate
For the Sigma, my advice is choose the earlier version which is probably the slightly better performer of the two. After obsessive testing at SRS one day, I also thought it was more consistent across the frame than the Tamron 10-24 alternative. You do get a slightly weird moustache distortion from...

The Front / Back Focus Debate
I am happy to be corrected, but I thought the AF Fine adjust feature only recognised Pentax lenses? Even if I'm wrong, however, using it with a zoom is a compromise; it's really best with primes.

I am happy to be corrected, but I thought the AF Fine adjust feature only recognised Pentax lenses? Works with non Pentax lenses as well. Only problem with Sigma is they tend to use the same ID number for multiple lenses which can be a problem if you have 2 with the same ID.

Rechargeable battery issue
Not so much an issue, more of a mystery. I have a number of rechargeable high capacity (2700 and 2900 mAh) NiMH AA batteries. For various reasons these don't get used very often nowadays, and when I went to them they seemed non functional. The battery charger that was supplied with some of them s...

Rechargeable battery issue
You should never let the batteries fall to 0v. They can sometimes be brought back to life... oddly usually in a cheap charger for a few seconds. Most of the the better chargers won't charge a 0v battery. But once the battery shows a small voltage the better chargers will do a better job and go thro...

Bracketing HDR Mirror Issue Part 2 - Can anyone help?
HI Back to this again! ARGH!!!! Earlier in the week (John Riley thanks) I was asking about HDR, bracketing and more specifically mirror up function. It appears that the K-5 cannot mirror up in between bracketing exposures before goin into Photomatix. When I set the camera up, focus sho...

SDHC card in a K-30 - Unusual problem??
Today I took the K-30 to work with a 7-Day shop 8Gb card (which I have had for a couple of years and not had any trouble with in either the K-5 or K-R)) in it and took some shots. Then the trouble started!: a) The camera could see the images on the card, but two different PCs kept could not us...

Viewfinder query
yes, an angle finder. I have an old Olympus "varimagni" which rotates and has a 2.5x focus magnifier; goes straight onto the K5ii.
