Even the girlfriend's Lumix pees all over my K5 when it comes to focusing. A compact camera with it's small sensor and massive relative depth of field will always 'pee all over' any DSLR when it comes to focussing in the type of situation you refer to. This is one of the primary reasons a compact ca...

This isn't a new issue and it's not an issue that relates only to Pentax, I am on enough non-camera specific forums to note that it is an issue that DSLRs in general seem to have problems over-coming in low light. At least the consumer/prosumer cameras, probably the people using the top of the range...

Accurate focusing with any DSLR just isn't possible :shock: See: http://www.slrgear.com/articles/focus/focus.htm

My personal experience from working with people using other brands and getting the chance to use them occasionally myself suggest that the Nikons have a slight edge when it comes to AF. The Canons fare about the same as my K-5. This, of course, is purely my personal impression. I have a similar ex...

After reading this thread I decided to use a gap between family commitments to fine tune the AF of my lenses for use my recently acquired K5. The ability to fine AF was one of the key drivers for me, as I was always compromised with the K10. On my K10 the DA*16-50 and DA*50-135 both back focused (...

I agree with Mark T's and Pentaxophile's comments. I almost always use manual focus in artificial light, or alternative use the live view in magnified mode if focus is really difficult and critical. I have no complaints about the AF abilities of my Pentax DSLR's although I don't have a K-5, only K...

How can you use manual focus? Are you using a focusing aid? When I have tried it I can get it pretty close but not close to get an exact focus point at f1.4/f1.8

When I have tried it I can get it pretty close but not close to get an exact focus point at f1.4/f1.8 I don't seem to have an issue with manual focussing - I can usually get it spot-on. If the light is really low I use 'Live view' and magn...

In the days of 35mm film SLR's we had massive magnification in our viewfinders and split screens, and focus m...

yeah I can't get manual focus spot on either. I usually just use a torch to give some light to the scene and sometimes to expose it to - I oft work in very low light and sometimes pitch black - so never without a good cree LED torch :)

I went shooting with a friend today me armed with a K-7 and him with a Canon 500d, both of us struggled to get AF to work in poor light. The only difference was when we were forced to pop up the flash, his sends out a strobe like effect with the light from the flash and pretty much nailed the focu...

I just did a very quick test between an Olympus E-620 & my Pentax K-5, dim light, a sheet of ukulele chords shot from a 45 angle. I was using a DA 18-55 WR on the K-5, and a 14-42 ED on the Olympus, so both were the supplied kit lenses. Exposure was f5.6, 1/50sec at ISO 1600 - metered same on bo...

I think anyone that is saying they can sharp focus in manual is probably using a larger depth of field and therefore a large margin of error. I cannot see how it is possible to manual focus otherwise.

If anyone is finding it difficult to manual focus a lens then first of all make sure the viewfinder dioptre adjustment has been adjusted properly. Point at a blank wall or area of sky, alter dioptre until the lines etched on the focusing screen are sharp. Do not try to focus on something the camera ...

I'm sorry but this is just plain wrrrrrong ! I bought MF Cosina 55/1.2 and K50/1.2 to use at F1.2 ! Achieving accurate focus is slightly more difficult than at say f2 but with the nice bright viewfinder that a 1.2 or 1.4 gives you, and a custom screen (though one of my K5s has the stock screen and...
