Does the built in K5II flash adjustment effect an external flash?

The +/-ev adjustment for flash in the camera affects the pop-up flash or any P-TTL flash unit attached to the hot shoe. As mentioned above it can also control external wireless P-TTL units.

As a matter of interest, I've found that with my K5-II and 18-135WR I get the best results with P-TTL on my 540FGZ if I shoot with the camera in manual exposure mode and a flash compensation value of about -1ev (either set in the camera OR on the flash - not both as they are cumulative). I've also found that using the A setting on the flash unit gives more consistent exposure results than P-TTL but is not as convenient when you want to alter things, for example aperture in order to change DOF.

I agree completely. This looks to be a terrific camera at a very competitive price which will suit the vast majority of Pentax users very well.

The negative comments and complaints that it doesn't do specific things (eg it isn't a perfect video camera) are in my opinion pretty pointless if not entirely unexpected. I remember reading the same sorts of nonsense when the K3 was released.

Pentax/Ricoh: De-cripple the K-mount! PETITION

I have no idea what point you were trying to make by quoting that very long list of voters?


I'm also struggling to find a valid point in your comments above. Wanting older lenses (which many of us have) to work properly (as originally intended) on our modern DSLR bodies has nothing to do with 'sentimental feelings'. It is simply a wish to have some functionality which really should always have been included in the current K mount.


As others have commented, describing old lenses as 'outdated glass' is a pretty strange thing to say. They are old, not outdated. They work very well on current Pentax DSLRs, and would simply be easier to use if the aperture feeler was incorporated into the mount, exactly as it was in all of the K-mount film cameras. My SMC Pentax 50mm F1.2 lens is far and away the sharpest of all my lenses. Describing it as outdated is ridiculous.

I stand corrected. I was just trying to get across that the crippled mount is about metering, not focussing.

Yep, any lens with an A setting will work on the crippled mount, because they have an electrical contact for the aperture. Similarly, any lens which you can manually step down will work because the camera is metering through the stepped down lens.


The problem is with K or M series lenses which do not get stepped down until you release the shutter (or use the green button). Because the mount doesn't have the aperture feeler, the camera doesn't know what aperture is set, and cannot meter correctly unless you use the green button.

I assume you are talking about M42 lenses? A manual aperture K mount lens doesn't get stopped down until you either hit the green button or push the shutter release, and without the aperture feeler the camera doesn't know what the aperture is set to until the lens gets stopped down.

That's interesting, but what does that have to do with wanting the aperture measuring lever built into the mount? Decripling the mount is about being able to use aperture priority exposure rather than manual. It has nothing to do with focusing a manual lens. If you are using live view with a lens with manual aperture adjustment, you still have to use the green button to meter and set the shutter speed.

That's certainly what Ricoh/Pentax say. The DA*s are categorised as water-resistant, whereas the WR lenses are weather-resistant. The former being more sealed than the later. I also suspect that due to the fact the DA WR zooms extend with zoom, this must cause air (and potentially some moisture or dust) to be drawn in.

I get very good results bouncing flash with my ancient auto thyristor sunpak. The fact that the flash unit measures the light returning to the sensor means that the exposure is good nearly every time.

Good advice. The experience of sitting in front of a computer with quality PSU, case and associated fans is far more pleasant than sitting in front of one that sounds like a jumbo jet warming up on the tarmac. The difference in price isn't very much either in the overall scheme of things.

Most people don't care if the mount can take old lenses either, or about a lot of features a particular camera has. As is obvious by the number of comments in this thread, there are a significant number of Pentax users who would like this particular feature. The fact that the majority of users don't want or need a particular feature isn't a valid argument for not having it. If you applied that argument universally all DSLRs would just have a progam setting with no other exposure modes.



Adding this feature would not disadvantage any user in any way, and as has been pointed out previously, the mechanics required are neither complex or expensive. You cannot be seriously suggesting that adding this feature would would cause Pentax to fall over as a brand? Nikon seem to have survived just fine and they have included this feature on a number of their camera bodies.



Only two changes (Hoya, then Richoh), and totally irrelevant to the argument in any case.

I started with the 18-135 on my k5II (along with the SMC 50 1.2 I had from my film camera).
It's still my most used lens, unless I'm doing macro work.

The 18-135 is surprisingly sharp in the middle even when wide open pretty much right though the zoom range and I reckon the edges are reasonably sharp except maybe wide open at 135mm. Stopped down to around f8 it's pretty sharp across the frame at all focal lengths. It's better than I expected it to be. Focus is quick and accurate, and it focuses reasonably close. I reckon it's a really good walk around lens and good value for the money.

Both Tamron and Sigma make 17-50 F2.8 zooms. Both get pretty good reviews.
Neither are WR though, and I'm not convinced that the construction quality of the Tamron is within a bulls roar of the Pentax lenses.

You can push the ISO a bit on the K3 without getting too much noise, so the 3.5-5.6 aperture on the 18-135 might still do the job for you. They are pretty versatile.

I'd also recommend the 18-135. It covers a broad enough range that you can leave it on the camera as the default lens and it will do a pretty good job most of the time.
That's basically what I do with mine. I swap to other lenses as the need arises, but if I need to just grab the camera to capture a moment, it's the best bet.

The water proofing and quick-shift focus over-ride are both handy too.

You can get diffusers for the pop up flash too, and they help a bit.

I've got an SMC Pentax 50mm F1.2 (otherwise known as the K version) and an SMC Pentax A 50mm F1.7
They both produce terrific results, and fit into the short tele range on a crop sensor camera.

It's also worth noting that by definition, a DSLR camera is a combination of electronics and mechanics.
Mirror, aperture blades, shutter.......?

Pentax bodies already have the mechanics to stop the lens down to meter, and for when you take a shot. Having the necessary mechanics to detect the aperture set on an older (non electronic) lens is not particularly complex, nor would it be expensive. Many people have chosen the Pentax system to take advantage of older legacy lenses.

It's not like Ricoh would have to start from scratch, this 'technology' is existing. It was included in my 1980s K2.

So you are correct at least in your closing comment. It is really simple......

Interesting. BTW, as a disclaimer, a decade or two ago I was a bit of a computer nerd, but these days I'm more of a user, and my knowledge has dwindled regarding newer stuff.

The board I'm getting in my new system is a Z97, but I didn't even discuss faster RAM with the guys who are putting it together for me. The Graphics card is a Gigabyte GTX750 TI 2GB which I understand is 'okay' for gaming, and pretty good for rendering, video editing etc. It was only about $AU160 which is around 85.

One thing the computer guy did say was that having a SSD is a very good idea and improves overall performance markedly.
