What lens Are We Waiting For?
I would have bought a quality 180mm or 150mm macro lens that has internal focus, has silent fast af and designed with flexible focus limiters. However having found a beautiful Sigma 180 F3.5 macro that is sharp and fast to AF on my K3, my need has now diminished a bit. 2nd, would love to replace my...

I think Ricoh should develop lenses going forward that will suit the needs of both aps-c and FF users, much like the D FA28-105 is enjoyed by both now, and current aps-c users can buy with a view to keeping when they go FF in future..... so forget the big, unnecessary 50mm and 85mm f1.4 ..... I a...

What mock-up primes were those? Back in February Ricoh exhibited pre-production models of the forthcoming 50mm and 85mm lenses, but it’s all gone very quiet on the lens front since.

There are two fast primes in the works, so maybe you could save yourself a bit of cash by waiting a little longer? There are also plenty of other makers providing fast lenses, although some are quite expensive. Who makes a 500/600 f4 for Pentax? I've never found one, and the 560 f5.6 is slow to focu...

Who makes a 500/600 f4 for Pentax? Who's got £8,000 to buy one (or even up to £11,000 depending on the make?) But this one's close and affordable: https://www.srsmicrosystems.co.uk/sigma-50-500mm-f4-5-6-3-dg-os-hsm-lens-pentax-fit.html That's the thing. Pentax would charge more than equivalent C...

I really don't see the point of suggesting £1000 Sigma zooms, manual focus lenses or 2x teleconverters. If he has the cash then nothing Pentax currently has (or is going to have) is going to compare with a Nikon/Canon 500mm/600mm prime ... especially when matched up with their top crop cameras. K...

I really don't see the point of suggesting £1000 Sigma zooms, Why? Because he asked who makes a 500/600 f4 for Pentax. Can't see where he says he's awash with £££. I didn't say I was, but I would invest. I've looked around for an FA 600, but it's still stupid money, it's also screw drive, and it's...

For wildlife it appears Canon is favourite with focus capability and lens choice, Pentax is not alone in concentrating more on other fields so if you have a particular area of interest it makes sense to go where that is served best. Kevriano, a camera or lens is not an “investment” unless it generat...

Dissatisfied with my mid-range zoom
Many thanks for all your helpful comments and suggestions. Mike-P: yes the images are still fuzzy at the edges, testing from f4 to f8. Worst at wide-angle (19mm) but still noticeable at the long end (50mm - see my example below). Algernon: I have wondered if I should have rejected it, as the blur ...

Dissatisfied with my mid-range zoom
FWIW, and going back in this thread a bit, my very early Sigma 17-70 is doing pretty well - not had any real issues with the edge definition, but then, generally, I'm not a pixel-peeper :D

Dissatisfied with my mid-range zoom
For a rough and ready lens test that actually means something, try pinning up a large newspaper on a flat wall. Make sure the camera is centred and parallel to the wall, on a very firm tripod, focus very carefully using live view and take several runs of all apertures. Use the 2 second delayed actio...

Wide angle
Hi Brian - I picked up the older version (not the f3.5 one) a couple of months back thinking I'd give it a bit of a try then probably sell it one - but a trip to the Lake District a few weeks back revealed it to be a superb lens on my K5iis. If you want to get an idea of what it can do then this m...

DA★ 11-18mm coming soon !
I'll take a look John, that would be interesting obviously I guess the closet the focus distance then the more obvious the difference.
