Sticky: About those WR body weather seals...User responsibility and best practice
Posted By JinDesu

One thing I think that should be brought up is that internal condensation due to moving from a warm to cold environment is to be expected, and is not a failing of the seals. Humidity levels inside and outside of the camera is the same regardless of seals or not - and temperature changes will condense the latent humidity.

I second this test. I freaked out once thinking my k-3 was dead when I left the door open and didn't pay attention. It looks practically non-functioning in that mode.

Anybody else disappointed with focus peaking?

When I had my K-01, focus peaking was pretty hard to use. I remember my friend's NEX-5N or something with adjustable peaking colours, strength, and so on, and that made it a lot easier to use - but it was sometimes overwhelming with the red.

My k-3's focus peaking is pretty solid, I can clearly see even when zoomed out where the peaking occurs. The silvery highlight of the peaking is visible, and if I rack the focus in and out a little, it makes it very clear where my focus is.

That being said, I wish they gave me adjustable colours, even if it's just 3 different colours (green, blue, and red).

Silly question - Exposure Scale on the GR

Ah, good to know that M has the exposure bar, I suppose I could change my shooting style to use M instead of TAv. Thanks!

Silly question - Exposure Scale on the GR
Posted By JinDesu

So this may be a silly question, but on my k-3 and other DSLRs, in the viewfinder, I have a little exposure scale that tells me if my scene is brighter, darker, etc. I don't know if that's the name for it, but it's something I've gotten used to using. On the GR, I can only find the option to show the histogram on my screen - and I don't like to use that for two reasons:

1) I don't know how to read it (not a big deal)
2) It takes up a ton of the screen in my opinion (bigger deal)

The alternative that I know is in the GR is that if my shutter and aperture settings cause overexposure at ISO100, it'll give me the !AE sign. This isn't a problem in the other direction because I shoot in TAv and I'll see my ISO jump, and I can adjust my shutter/aperture based on the ISO value. So my trouble is when I have a daylight scene and I'm at ISO100 and it gives me the !AE sign, and I don't know by how much I am overexposing.

When I have the scale in my k-3, I can see if I'm 3 or more stops, 2 stops, or 1 stop overexposed, and I can very quickly adjust my settings to match. On the GR, it's a little bit of a crapshoot for me if I don't have the histogram on. Does anyone have a solution for this?

No, he may be making a joke, but it's just going into live view which runs the sensor continuously. Similarly if you go record a video for too long in normal or warm temps, you'll get the sensor overheat symbol. This is just taking that into a cold temp situation.

Hi Chuck,

I submitted an inquiry into the B&H customer service, but I was hoping you might be able to help expedite things if you see this before they do. I recently had a charge to my credit card that I did not make, and (somewhat amusingly) the person who used my card sent it to my house address. I assume they wanted to take the box from the front steps, but someone was home.

Please PM me if possible and I'll give you the details. Again, I'm just trying all avenues as quickly as possible to get this resolved. Thanks!

Thoughts on ISO
Posted By JinDesu

Image noise is the sensor (of film, or music recorder, or whatever) lacking enough distinct signal to differentiate from general ambient signal - in the case of a image sensor that ambient signal is the general electrical field around the sensor. Where the incoming signal is not distinct, the local ambient signal may trigger the sensor pixels to register as red, green, or blue, and create the noise. Just as if you had a microphone and you hear static from the ambient electrical fields around the signal delivery circuits within.

ISO determines how much electrical amplification is applied to the sensor. A higher ISO is a higher electrical amplification to improve sensitivity to the lower input signal. Higher electrical amplification has the side effect of having a strong electrical field around that sensor, and therefore has a better chance of triggering the sensor with noise instead of the incoming signal.

Darker parts of a scene will have noise as the incoming signal from those areas may not be strong enough to differentiate from the electrical ambient signal. If you shoot a sunlit scene with a dark shadow even at ISO 100, the electrical ambient signal on the sensor may be stronger than the few photons you receive from that region in the shadow.

Similarly, out of focus regions may generate more noise because the incoming signal is seen as indistinct by the sensor.

Anyone actually use their OVF on their GR

I tried my GR out for the first time (ish) on Saturday, and I have the GV-1 OVF. After a few shots walking around with it, I sort of felt that it wasn't worth using for me. Partly because my glasses made it harder to see through the OVF, and partly because I kept having a slight tilt that would show up in the photos.

Maybe it just needs a bit more practice on my part though.

K-1 tilt screen support mechanism froze
Posted By JinDesu

The concern isn't so much that the camera is going to die randomly, but that the small joints in the articulation arms will react badly to any non-lubricating liquids being introduced into them. But that said, if you accept the responsibility, then that's your choice. I don't know of any coating that makes things freeze resistant. Most products in this category tend to be hydrophobic to prevent water from staying and freezing.

I'm confused. If the concern is to unfreeze it after your shots so that you can pack the gear, why not use the hand warmer as suggested? The poles are small and unlikely to take a large amount of heat and time to unfreeze them enough to pack, and it's not like the sensor will be affected at that time.

If the concern is to keep the poles unfrozen during the shoot, that might be quite difficult. Any joints on the articulation pole could be adversely affected by an anti-moisture repellant, and to be fair when it's that cold, even anti-moisture coating may not keep snow from collecting on top and then freezing anyways.

I think what Photolady is saying is to put it on a tripod, set it at the troublesome shutter speeds, turn off SR, use a remote or something - and then take a shot. If it's still blurry, then something is wrong with your camera.

Probably ensures the complete lack of shutter vibrations on the image. I don't think it specifically does anything to the image. Good to know though.

Archimedes, you have a typo in the second set of images:

"For comparison's sake, here's the DA 50mm f/1.8:

DA* 55m f/1.8 at f/1.8, DA* 55m f/1.8 at f/2.0, DA* 55m f/1.8 at f/2.8"

That threw me off when I scrolled up into it.

Any way to state that you had wobble since owning it and therefore the impact damage was prior to you owning it? I understand that while you do have the Squaretrade accidental coverage, but manufacturer/distributor damage should be covered by the manufacturer - and they should be made to cover it.
