An alternative 28-105 for the K1 ?
Seems like a reasonable lens, especially for the price. Wonder how it stacks up towards sunlight versus the HD coating on the D-FA 28-105mm WR and how much louder the focus is (not an issue for most but may be an issue for some).

Wonder how it stacks up towards sunlight versus the HD coating on the D-FA 28-105mm WR and how much louder the focus is (not an issue for most but may be an issue for some). All these shots were taken without a lens hood (it didn't come with on...

An alternative 28-105 for the K1 ?
I managed to get a genuine Sigma lens hood and also work out how to set the Auto Focus to spot focus so took a few more shots today. For completeness here is another 100% crop of one of the magnolia buds. Taken at 1/500s and f/8. Again the camera jpg with no PP except for the crop.

HD Pentax D FA 70-210mm f4 ED SDM WR - First impressions
Delivered less than an hour ago (thanks to the SRS guys) I thought I'd give my initial impressions of the latest release from Pentax. It has a nice feel to the lens, the zoom and focus grips are of the more recent type (as on the D-FA*50/1.4) and do feel slightly more positive than previous versi...

HD Pentax D FA 70-210mm f4 ED SDM WR - First impressions
Looks like you have all your ducks in a row with this lens John :D:D Quite literally Peter :wink: I tried it out this afternoon with some indoor grandchildren shots - with and without flash - and the focus is fast and accurate in low light, my 60-250 was a great lens but wouldn't keep up with thi...

HD Pentax D FA 70-210mm f4 ED SDM WR - First impressions
Ok, wasn't aware of that one, thanks John At over £1k more then the F4, it'll have to go on the back-burner for a while, particularly as no bonuses will be coming my way for a while

DA* 16-50 SDM motor failure...
First point would be to try and get the SDM working by turning the focus ring while attempting to AF. If that won't work then get yourself an old body (K-5 or older) and convert it to screwdrive yourself, it's pretty straightforward. If you need help then let me know.

[quote:3496ace15f="BruceStrachan"]Been Quoted £300 to get SDM fixed... Only paid £360 for lens.... Anyone know a place who will convert to screw?.. That is twice the price I paid at John Pyle, the official repairer, for my 50-135. Do you have contacts for John Pyle could be handy.[/quote] I str...

SDM in general
Sometimes I wonder how Pentax managed to survive at all. I own four Star lenses - supposedly professional standard lenses and now only my 60-250 is working as it should. The sdm drive in the others either doesn't work or only works occasionally and one will not even manually focus within a certain...

SDM in general
I'm really sorry to hear about your SDM * lenses, Cborg, you've been unlucky and are right to say that this is an issue that Pentax should have addressed a long time ago. Fortunately the new range of D-FA* SDM lenses have a completely different ring motor SDM mechanism which I understand if far str...

SDM in general
I at one time owned three of the DA* lenses. 16-50; 60-250; and 300. The 16-50 was troublesome in that it needed me to manually focus a few times throughout the range, then AF throughout the range after which it behaved normally. The 60-250 and 300 both worked perfectly. I only own the 300 now and i...

SDM in general
I own two star lenses - the 60-250 and the 50-135 plus the 17-70 which is also a SDM lens. I haven't had a problem with the SDM on any of them. The 17-70 hunts for focus and seems to have got worse as it gets older, but that isn't an SDM problem. It sounds like you have been really unlucky with yo...

Conversion to screw drive.
Is the conversion reversible? i.e. put it back to SDM?
Posted by JAK on 25/02/2020 - 20:45
Conversion to screw drive.
Yes I believe so - the camera saves a file automatically on your SD card during the process called BACKUP.LNS or LENSEEP.LNS and it is recommended you keep copies of these files on your computer, before deleting them, in case you do wish to go back to SDM.

Conversion to screw drive.
Now completed sdm to screwdrive da*16-50, da*50-135 and da*300mm lenses. All focus faster and, in at least one case, more accurately. Because these lenses are so solidly built, the mechanical noise is well dampened and is, for example, well below that of the F zooms. Roger

Pentax lenses are weird but wonderful
The FA20-35 is hardly ever off my K-1, It's a very versatile, compact option that doesn't need dinner plate sized filters. It's a very wide zoom, CA will always be a factor (even the ££££ modern lenses still suffer from it). Yes, it's plasticky and the focussing ring isn't the best, but it's reasona...

Pentax lenses are weird but wonderful
I have accumulated a number of Pentax primes with focal lengths between 50 and 55mm. All have their virtues, and vices, but that with the most distinctive and pleasing character, particularly, to my eyes and at apertures of f/4 and below, is the K-series 55mm f/1.8 8) An example illustrating what I ...

Still some third party lenses in K mount
the Irix 150mm f2.8 Macro has almost enticed me in once or twice It's a really, really lovely lens. Repeat after me: "Resistence is futile, resistence is futile, resistence is futile ..." :twisted::twisted: Seriously, if the 45mm is as good as the 150mm, those who like that FOV are in for an opti...

I'm looking for a decent 50mm FF lens for my new K1 ii
Are you happy with manual focus? If so, this really opens up the playing field for you. There's a swathe of excellent film lenses that work nicely on full frame. I recently enjoyed using the SMC-M 50mm f/1.7 for about a month. Decently sharp wide-open, nice bokeh, smooth to use and an abundance of g...
