Sample images from the Pentax HD PENTAX-D FA 150-450mm F4.5-5.6 ED DC AW
Blimey Pentax is this the best you can show us? That flower shot is 'orrible. The out of focus white flowers and stems look like they are either suffering from motion blur or internal reflections causing ghosting. I'm certain it can do better than this. Get rid of the photographer before you post mo...

Sample images from the Pentax HD PENTAX-D FA 150-450mm F4.5-5.6 ED DC AW
Pentax have never turned out a poor lens in the sort of price bracket and market segment we're looking at, so when I buy I'll just be buying, with confidence. I agree, my comments related to the photo which is probably not a good demonstration of the lens's capabilities. On a slight tangent I have p...

Well, it's starting to happen in a big way. It looks as though the only thing holding back Pentax may have been the cash to realise the plans. No doubt other manufacturers are starting to feel there's some serious competition coming their way.

Wow - really good to see this and you're right, it will be expensive if you want to assemble the ultimate lens system around the new FF body but as ever it's a case of slowly assembling the system for most of us. I actually think Pentax would do better if they made the FA series lenses somewhere be...

Easiest way to mount M42 lenses on K-3?
Using the Pentax Adapter K, the correct technique is to screw the adapter to a lens. Then attach that lens to the camera. To remove the lens, simply unscrew it and then screw in another lens as required. In other words, the K-3 will have been changed into a screw mount body. When you want to go b...

Easiest way to mount M42 lenses on K-3?
I have various Pentax and non Pentax 42mm screw lenses. I Had some original screw to K adapters and bought more Chinese made ones. (Very cheap) I unscrew the little spring on the adapters and tightly screwed the adapters on to each 42mm lens. You can leave them on the lenses and they will h...

So which lenses will you buy for the new FF
I have three FA* that I am eager to test on a 24x36 DSLR: FA* 24/2, FA* 300/4.5 and the FA* 28-70/2.8. Besides that I have some nice manual focus lenses that I hope will function well on fullframe, amongst them: K28/3.5, A50/1.2, M100/2.8 and the Voigtlander Ultron 40/2. I dream about the FA limited...

So which lenses will you buy for the new FF
When the K-3 was launched I was hoping the investment Ricoh had put in would indicate a FF body was on the horizon. I'm also still shooting film so it made sense to get some FA lenses (for coverage & aperture rings) to add to various manual focus lenses I have historically. Before I knew it, my 'K3 ...

So which lenses will you buy for the new FF
. . My 300mm f4 has been tried on my 35mm MX and KM camera`s and looks fine so that should be a safe bet for FF (it looks optically the same as my old 300.f4 that I bought in 1977) (SRS Microsystems very kindly tried it on a 35mm film Pentax for me before I purchased it too!) .I have a 100mm Macro...

So which lenses will you buy for the new FF
The Sigma 24-70 f2.8 remains as one of the best PK zooms ever made; also a full-frame lens. It will be interesting to see if Zeiss ever brings back some of it's PK. The Schneider (currently highest priced PK) tilt and shift will become considerably more appealing for full-frame. I'll still end up...

So which lenses will you buy for the new FF
Thankfully at least three of my existing AF lenses (the two DFA Macros and DA70 Limited) already work with FF. Though if I was getting back into DSLRs I'd probably go with the K3 rather than an FF at this stage.

To repair or not to repair? DA* 16-50.
Just another option.... I believe there is a software hack that can make the 16-50 revert to screw drive focus.

To repair or not to repair? DA* 16-50.
The Pentax 16-50 (Sudden Death Motor, SDM) is simply not a reliable lens. One could never rely on having that lens without having a back up. Quite sad really. That one would actually have the genuine need for a secondary lens in case of failure of the Pentax 16-50. That 16-50 is by far one of the...

To repair or not to repair? DA* 16-50.
Loved both my DA* lenses and they where regularly used and both bought used and never suffered any focus issues. I went from a tamron 17-50 to a DA* 16-50 and the difference in image quality was there to see, as was the WR and silent focussing. My Tamron also hunted for focus far more than the 1...

I'd forgotten about this thread! The quote was for around HUF 40,000 to 60,000, need to get back in touch with them to confirm but I have to put it back now as I have to have a trip back to the UK this month. That's in the order of £100-140 or so. Will have to confirm obviously, they were waiting fo...

To repair or not to repair? DA* 16-50.
old thread i know but ive been using a 16-50 that the sdm failed on for ages now as a screw drive. it doesnt bother me one bit that it makes a bit of noise (like the majority of the pentax line up). its one of my most used lenses along with the 50-135. dont get me wrong id prefer it to be silent bu...

To repair or not to repair? DA* 16-50.
I had what I thought was a SDM failure on my 16-50 but it seems if you don't use it often it "goes to sleep". I found that by twisting the focus ring back and forth and pointing it up while pressing the AF button then down and press the AF button many times it appears to have woke it up. Try it bef...

Pentax Forums first impressions of the new 16-85mm
Bit surprised they didn't compare it to the DA17-70/4 - OK it's not weather sealed but it's more appropriate than the 18-55 IMHO. If I didn't have the DA17-70 I might prefer the extra width, WR & DC motor of the 16-85 (but, it's a bit slow at the long end) although I don't use focal lengths between ...
