Pentax 100mm Macro - Non WR vs. WR
All of the 100mm Macro lenses are reasonably quick to focus, but all can suffer from hunting if the subject is of low contrast/dynamic range. Given the increased travel of focussing a macro lens, this can be a real pain.

Pentax 100mm Macro - Non WR vs. WR
I also changed mine from the non to WR (Only because of a good deal) and have not noticed any difference in the focusing. The focus ring is smaller on the WR but not a problem for me. You loose the aperture ring on the WR so not so useful for the film cameras. The feel of the lens is more solid b...

DA* 300 AF noise
Hello, I just received my DA* 300. Everything looked fine at first but I noticed an annoying "whining" sound when the AF goes from 1.4m to infinity. Is it something I should worry about? Would you send it back for a replacement? I tried to record the sound with my phone for those caring to hav...

That does not sound good. Something is rubbing in there that shouldn't.:shock::shock: I'd take it back and get it replaced!

which wide to hire for Olympic Park architecture?
Same dilemma as me, Sharon, though we didn't get any Olympic tickets:( After lots of research and head scratching I had decided on the 8-16mm too, for the same reasons as you - great reviews and (sort of) affordable. I also considered the hiring route for an upcoming trip to Italy, but thought...

which wide to hire for Olympic Park architecture?
I have some concerns over the 10-20mm as well, but any lens will have it's fans and detractors. On the whole there are plenty more people who love it than hate it. I've bought mine from a forum member who has good feedback for selling before and says he has had great images with it. That's probab...

I had the same problem with the K5. Had to pre-focus.

I've had the K5 since my May holiday. Huge improvement with the 55 -300 DA over it on my previous KX and KR models.It had no issus in sunny Greece. On my KR I found centre focus the best method but on the K5 the 11 point auto settng seems better even at extreme telephoto. I guess this is because ...

poor af pentax 55-300
I brought a 55-300 back to Oz to sell but due to the wonderful light here and its IQ, I have held onto it. It may well be a different story in dull weather. However, that’s one reason I use other kit. I don't really see a difference in AF between the K7 and K5; even the K10 is good with this lens...

I thought this lens worked best in manual focus. The ideal body would be the K30, IMHO - focus peaking!

poor af pentax 55-300
For ANY fast moving objects, I always recommend disabling the "Focus on Half Press" and pre-focussing using the AF button on the back ;) (see custom settings) That way the camera will shoot instantly when you press the shutter - it doesn't care if it's in focus. You learn to focus with the thumb...

That way the camera will shoot instantly when you press the shutter - it doesn't care if it's in focus. Personally, I use centre focus only with this technique. Works exceptionally well in dark conditions too (e.g. stage work) K-5 allows you to bypass AF lock so you can shoot instantly using th...

I would rather eat Brussel sprouts I too love brussel sprouts! I wouldn't even attempt to take a picture of something so challenging PERIOD let alone with a DA55-300mm. In general use (inanimate objects) I found the DA55-300mm extremely obstinate in it's focussing, so for me, manual focus was a bett...

poor af pentax 55-300
Must admit I don't worry about it as I always shoot raw and process accordingly but I find Pentax cameras have always get it wrong when doing air shows on cloudy days using AWB. I experianced the same when I went to Shuttleworth. Slow prop plans and a Tamron 70-300 actually worked very well for m...

I don't process everything, but do have a quick and easy batch process set up that could do it. It really doesn't take that long at all, unless you are aiming for something very specific. The tower picture that won the weekly comp a while back took a fair bit longer as do some of the HDR's (which ar...

Overcast conditions will lead to poor contrast and make focusing difficult. Couple that to the slow focusing of the 55-300 and it will be tough. If you're photographing planes, surely pre-focusing manually will do the trick? But only up to a point as this lens (more so than others) will often "hun...

Using a teleconverter
I am using a Pentax K10 with a Tamron 18-200 lens, and it works fine on automatic settings I have a Bower MC 2X Pz/AF teleconverter, but when I added this, it did not seem to want to "auto" focus. I manually focused and got a great shot. Shouldn't it auto focus? (I was shooting through a window)

Using a teleconverter
Mike-P, Yes it is 6.3. I understand what you are saying, but don't know why at f13 it would not "auto" focus. I am way over my head in the equipment I have...I try to learn, but forget so rapidly.
