Lens Issue?

Personally, I prefer a clean, dry cloth. You could use a tiny amount of alcohol on it if you want, but I've never needed to.

And yes, the metallic "beads" around the camera and lens mounts. Just buff them clean with a soft cloth. They can easily accumulate a film of grime that's almost impossible to see with the naked eye, but still enough to interfere with connectivity.

Even if it doesn't solve your current issue, it's good practice to clean them every so often as a preventative measure.

Clean the contacts on both the lens and lens mount. If debris is interfering with the proper connection between lens and body, you can get some pretty strange effects. It's also remotely possible that the lens is damaged.

2 years in (with a break for the last several months), and still very happy with my K-r, but still extremely unhappy with the direction Pentax is going.

I'd like to stay with the system when I eventually do have to upgrade/replace, but if they put themselves out of business with these stupid lens hikes and lack of new bodies, I'll be jumping with my next camera.

Pentax K-r JPEG image style setting

I think you'll find the vast majority here shoot in raw, so as to take full advantage of what can be done in post. There is an awful lot of data lost by using jpeg, and it makes correcting exposure and white balance more difficult after the fact.

Personally, I keep the jpeg settings as baseline as possible. The natural setting will work in a pinch. I very rarely shoot jpeg though, and when I do, it's usually raw+jpeg.

What editor are you using to process your images? And how well versed in using that program are you?

Yes, I've had the same issue. I figure it's because the camera is calculating the flash without "knowing" about the diffuser, which cuts light by a significant percentage (depends on the diffuser, but they all do to some extent). If you're using Av mode or something along those lines, EV compensation might do the trick, but you would have to figure out how much of the light from the flash is lost in diffusing it.

I haven't handled the K-30 myself, so I can't vouch for it, but I can say that other Pentax models that have come in bright colours (red and white K-x/K-r) do hold their colour and appearance very well. I doubt Pentax would want to change that reputation now.

Horrible. Very disappointing. Maybe I'm expecting too much from a compact camera sensor, but the artifacts in that... If they released this as a sample of what they think is good, imagine how it will perform in real life situations.

Personally, I have no use for this, but I see it as a VERY good move from Pentax. This is an important market segment, as it reaches beginners who would be enthusiasts. Someone who has a good experience with this camera would be much more likely to select a K-5, or its successor, down the road.

The popularity of the Panasonic FZ series shows that there is a market for this kind of bridge camera. Good on Pentax/Ricoh for recognizing that. I wonder what the size of the sensor is in this.

For some reason this made me chuckle. For a LOT of people who start out on digital, film seems very daunting for just the reason you feel it's simple. I think that you will have no trouble at all going the other way, from film to digital. Just being able to "chimp", to instantly review your shots on the camera, that has to make it a lot easier to find your way through settings and finding the proper exposure, as you get used to it. I'd say don't even worry, try one out in a shop if possible, and then go for it.

What is a good zoom lens for reverse lens macro?
Posted By Philoslothical
Replies: 5

Speaking generally, you will get better results with primes. Zoom lenses can also be quite unpredictable in their working distance when set on tubes, sometimes with the focal plane ending up inside the lens, making it useless. You have a good pair of lenses right now for working with tubes. Another option would be reverse lens stacking, which would get some higher magnifications quite easily. If you picked up something like a 135mm, and reversed either of your current lenses on it, you should get some good stuff (as long as the host lens is decently sharp, too). Your 28mm reversed on a 135mm will be a bit shy of 5:1 magnification (too much for handheld, really, but it can be pretty wild on a tripod with a rail), while your 50mm will attain a little better than 2:1, which should be good handheld, too.

If you really want to try macro with a zoom lens, I'd suggest getting a Raynox or Opteka addon lens. This will keep your working distance constant, while your zoom will affect magnification. Both of these are better than simple +dioptre lenses, in that they use multiple elements to correct for chromatic aberrations, and are generally much sharper, too. The Opteka one is both stronger and cheaper than the Raynox, while still giving pretty good image quality. If you use too long a focal length, it really brings out the worst in your host lens, with some pretty wild distortions around the edges if the host lens isn't flat field sharp. Still, it's plenty usable at the 1:1 through maybe 3:1 range, which is all you should be doing handheld. This is the lens I'm talking about. Below is an example of it in use on my cheap Sigma 70-300mm.

Everyone seems to forget the Sigma 70mm f./2.8 macro, which is scary sharp, perhaps a bit sharper than the 105mm even. Slightly less working distance than the 105mm, but a nice focal length for a lot of purposes outside of macro, too.

Which lenses do I keep and which do I sell ?

I'd agree with that statement, too. I was careful with my wording, and based it on other comments I've seen throughout the forums. Some people will definitely feel as you do, some will prefer to use something less staggeringly sharp than a macro lens. It all comes down to individual style and preference, I was just suggesting that OP shoot with both and decide for himself.

The 85 f./2 is a little faster, too, which might be useful in some circumstances. I still say OP should not be in a rush to sell anything. He doesn't have anything excessive, at all.

One more thing to consider, with the 85 and 90: Some people don't prefer macro lenses for portraiture, because they are extremely sharp, and they bring out every blemish on a person's skin. This can of course be subdued in pp, but your 85 might have a better character for this kind of shot. You'd have to experiment and see.

Don't think along these lines. 35mm equivalency is only a useful metric for those that shot film first, and moved to APS-C digital. ALL your lenses are "for full frame", but focal length is focal length, there is no use is going through mental conversions if all you shoot is digital.

You have a nice little collection going. I wouldn't sell any just because. I'd go out and shoot with each, several times, and then decide if I wanted to part with any based on the character, quality and convenience of each lens. Honestly, I think you have a good start here, with something for most purposes. There's nothing wrong with leaving a few on the shelf when you go out, and taking a different set with you on different excursions.

Someone else had this issue with a particular lens recently, and it turned out to be a slightly bent aperture lever. Have a read here and see if it matches your problem.

If that doesn't solve your problem, try cleaning the contacts on both camera and lens. This is good practice anyway, but contact issues are common and can cause all kinds of weirdness.

Is the mount on this lens bare metal, or painted/anodized black? If it's the lens causing the issue, then it must be a case of the lens improperly shorting some of the contacts. Try insulating the lens from the body with a small ring of paper or something, to test this idea.

I don't know too much about Canon, but with Pentax, the pixel mapping feature that masks hot pixels is only active when shooting stills. If your Canon is the same way, then capturing stills from the video output wouldn't use pixel mapping either, so they would show up.
