Pentax K1 K1ii advice
I cannot compare with the K5IIs but I will say the image quality is excellent, with the qualification that it depends of course on the lens being used. The Sigma will give excellent results BUT you should check if the mount has been modified - if so it will have a chamfered edge; the original moun...

Pentax K1 K1ii advice
Hi All After the announcement of the K3 iii delay I decided it would be a long time before second hand K3 ii's came down in price so I took the plunge and bought one from ParkCameras. Just under 12000 clicks on the clock. Ordered yesterday afternoon and arrived 10am this morning, it appears in exce...

Pentax K1 K1ii advice
Agree with Mike-P as above, I use the plug in from Nik collection for cleaning up noise I've run my K3ii @ ISO 3200 fairly often particularly with fast moving jets, the files are pretty good and do clean up in post, I though I'd run it higher but cant find any examples and again all in camera pro...

Dust particles inside lens
I've always regarded anything claiming to be weather or dust resistant (or proof) as meaning that you can take it out in bad weather or dusty conditions and it's unlikely (but not impossible) to come to any harm. However, if I do anything that affects the protective barriers, all bets are off. A bit...

Infinity focus gone on my early version Super -Takumar 35mm f2
I sent it to Alan Marlow -- he quoted £40 for setting the Infinity focus and £60 to strip down and clean and re-grease the SMC Takumar 200mm f4 with correct grease. The SMC Takumar 200mm f4 cost £61 NEW in 1972 from David S.H. Leung camera dealer of Goodmayes ! Repairs are a big chunk out of my r...

DA* 50-135 focus issue
Sounds like you have something with AI installed... always when threatened with mechanic the symptoms miraculously disappear...our old Golf was a pig until it got onto the road the VW garage was, then it ran perfectly. Is the problem with AF at low light? It's been a problem with my lenses and ...

DA* 50-135 focus issue
Is the problem with AF at low light? It's been a problem with my lenses and the lens hunts (not limited to DA* glass either). If SDM works on other occasions it doesn't sound like the SDM motor but maybe the sensitivity of the AF sensor... Battery maybe? Light level made no difference. What I c...

Bigger lenses
As I suggested in your '250mm limit' thread, one of the Pentax 55-300mm lenses is a good starting point. Apart from anything else, get one with quick-shift (not sure whether they all have it) and you can manually tweak focus if auto-focus is having trouble (as it very often will if the background is...

The new DA* 16-50mm f2.8
So the recent trend in Pentax pricing is for APS-C gear to be significantly more expensive than the FF equivalents? Optically, the closest FF lens to the new 16-50 is the 15-30 f2.8 and that's about the same price. Comparing with the FF 24-70 is a bit of a red herring, optics cares nothing for senso...

The new DA* 16-50mm f2.8
So the recent trend in Pentax pricing is for APS-C gear to be significantly more expensive than the FF equivalents? Philip It's starting to look that way. Fujifilm have lead the way in producing top-notch lenses for APS-C and pricing them as top-notch, regardless of sensor size. Perhaps Pentax ...

Filters?
The thinking is that UV filters are not needed on digital cameras as their effect on film doesn’t come across on a digital sensor - don’t ask me why, I am not that technically minded. They were more often kept on for lens protection as you say, I do sometimes use them but you are probably better off...

Filters?
Generally I always try to remember to install a lens hood, not only to exclude stray light but also to protect the front glass from accidental impact damage. However, I also agree with Rob - always using a filter removes the risk of accidentally damaging the front element when cleaning. I mostly h...

A tomb with a view
All the chatter about lenses recently got me to visit a favourite place, (St. Lawrence's churchyard in Meriden) with a macro lens. I put my preset 50mm f4 Takumar on the K1 and used it for anything but macro work. It is generally agreed that most macro lenses can be used at infinity but I was quit...

Buying from Japan
Useful to know. Thanks to both. My only trouble now is that I'm thinking of saving my money and getting a top quality bridge camera, one of the 1" sensor jobbies.. They seems to have got a lot more going for them in the last couple of years.

Tair-3 300mm f4.5 GRAND PRIX Brussels 1958
I owned one of these strange lenses many years ago and never really got on with it, but with more experience and a different expectation I now know to use lenses for their character rather than just looking for ultimate sharpness. The copy I picked up yesterday was under £50 so I thought I'd give...

Back Focusing HD DA 70mm F2.4 Limited
This is the first time that I have found a lens to be this far out, particularly with it being a new Limited. Back/Front focus issues have been with us since AF first appeared in the 1980's. Only with higher MP cameras and the ability to pixel-peep do we notice them as much. They can be caused by...

Pentax DFA*50mm 1.4
I’m just curious about it, I’m thinking of purchasing the dfa*50 1.4 ,maybe by Christmas I’ve very recently got my hands on a k1ii with 400 odd shutter count and I’m thrilled to be back in full frame or 35mm as was to myself in the film days. I know some of the members on here have far more skill...

Lens for shooting family around the home?
I would suggest one of the "plastic fantastics" - if on crop sensor the 35mm f/2.4 and if on full frame the 50mm f/1.8 Pentax lenses.

Lens for shooting family around the home?
Given your standard zoom lenses are APS-c lenses, I think suggestions of the 35mm f2.4 DA or maybe an SMC-FA 35 f2 will be better, or if you can find one of the wider FA lenses cheaply, or the DA 21 Limited. I think you'd find a 50 mm too restrictive on a crop sensor body. Alternatively a DA*16-...

A macro lens that is not a macro lens - Radionar 50mm
There is a whole series of Schneider Kreuznach Radionar lenses, all of which have quite a following. I have shown results from the 1:4.5 105mm in the past and I have now found time to have a play with my latest acquisition - a 1:2.8 50mm. Here it is on my K1. (image taken with a 1936 105mm Triopla...
