When is a Pentax not a Pentax?
I've just had a call from the shop to say that Pentax have agreed to replace my 16-45. So although I reckon they broke it when they were adjusting it, implying that Pentax QC isn't what it's cracked up to be, the fact that I now have a shiny new lens suggests that they do indeed look after us and va...

When is a Pentax not a Pentax?
If you want fragile then the "F" series 50mm F1.7 auto focus is extremely fragile. The whole front where the filter would screw in is plastic. The number of these I've seen with ciplled, cracked or missing bits is very high. I kept a filter on one of mine just to keep the chips ...

Sigma 400mm f5.6
Any good? I've seen a few of these on eBay recently - some went as low as £110.00. There seem to be black ones and grey ones!!! :D :shock: :? Anyone know the difference? If this is the Sigma A-Series 400mm F5.6 (non APO), there are black ones, grey ones, MF ones and AF ones. There's no differe...

fixing lens distortion on sigma 10-20
You can also try a compromise at the time of taking the picture. Just because you can't zoom out or move back far enough to get the whole subject in frame without tilting the camera at all, it doesn't mean it's not worth zooming out a bit - to enable the camera to be less extremely tilted. Just cr...

What lenses for a wedding??
I did a wedding for a friend a couple of months ago and shot with one lens on a K10D. This was a Sigma 17-70 2.8-4 and I found the extra length to be very usefull for individual portraits as I don't like getting too close to my subjects and also the subject has a bit more of their own space. I found...

What lenses for a wedding??
I'll be doing a family wedding in a few months time and was wondering what lenses i should take with me. Not exactly the same, but I covered a family party (90th birthday) and I mainly used the DA* 50-135, my reasoning for this was that the objective was to get candids, may being shot at about the ...

What lenses for a wedding??
I've found myself in the same boat as you Clarky! Original plan was 2x K10s + DA*16-50 & DA*50-135, we have one flash, need another. Then I bought a 43mm Limited fairly cheaply 'just to see what the fuss is about' and realised that if we want to pursue this more professionally, there is de...

What lenses for a wedding??
also my experience with the 50mm macro lens is this: the af on a macro will go slower and hunt more, than a comparable fast prime). so it's best to use manual focus, if you're good at focussing in low light. if not, do tests to find out how good your lens works in the dark. let me know that work...

Shake reduction on manual focus lens
When I attach a manual focus lens the K10D asks me for the focal length and so, with my 90mm Tamron I choose the nearest it will let me (85mm). If I use my 1.4X Tamron teleconverter am I then to choose the nearest to 126mm (120mm) or do I stick at 85mm. Thanks.

Well, because you need to stop down to get good front to back sharpness and always go to ISO 200 unpunished on the K10D you could consider ditching your kit lens and get the: Sigma 18-50mm F2.8 EX DC Macro instead. A wonderful piece of glass and well within your budget. Or you could go for the: smc ...

Sigma 30/1.4 Razorsharp in the middle, slightly wider. -Linus- thanks Linus, one question do you have the Sigma 30/1.4 and if so, what body do you use and any disadvantages with it you can name. Does anyone else have this lens: This seems to be my favourite choice at the moment, any exp...

F2.8 zooms are becoming less expensive. The Tamron for example is £259. Pentax-FA 28mm F2.8 is better than Pentax-F 28mm F2.8 according to some reviews and tests, but actually I found my F version was sharper wide open than an FA I tried. Its auto-focusing is very fast and reliable, and it's re...

:( Blimey, what a can of worms I have opened for myself :shock: I will have to go away and a very quiet think about all this and try and understand once and for all about this aspect of digital photography.

Pentax 31mm - Advice needed!
Bought my 31mm from Canada, £409 with postage, £55ish duty, took just under a week, no problems. Also bought a lens from Japan took 3 days, no duty, no problems. I would suggest putting in an offer at about the import prices, then drive down to pick it up, at least if it is not as described, you ...
