Helios on k20d
Hi I tried my Helios lens with pentax converter ring on my k20d and I am a bit puzzled. When I used it previously on my k100d, camera asked me what focal length this lens is. Then it worked nicely with manual focus, but everytime I focused on something manually with half pressed shutter it beeped ...

Helios on k20d
Should k20d ask for the focal length Only when SR is turned on. It needs the FL to calculate the amount of sensor shift. it beeped when in focus. K20d does not do any of this is the beep option turned on in the menu? And what will shake reduction help with? Apart from reducing shake? Absolutel...

Seven Lenses
As it happens, I'm in the process of rationalising my lenses down to seven: Sigma 10-20 DA 17-70 FA 50 1.4 DA 55-300 A 50 1.7 A 100 F4 Macro Sigma 50-500 Both my 400mm primes are going. It'll be very sad to say goodbye to both of them, for very different reasons. The Sigma is compact, ...

Seven Lenses
I am surprised with the amount of DA*s listed. Going by the other forums they are Pentax's version of the antichrist. Howls of despair anytime someone mentions SDM :) I don't hang out often over there, but I've not heard much if anything bad said about the 50-135 here. The 16-50 certainly, seems ...

Robbie, Mike & Chris. It's not strictly true that they feel DA* zooms were forged in Hell but they definitely prefer primes. Here's the survey I ran over both forums a while back :

advice please on 35mm and/or macro lenses
I'm looking for a good standard/wide angle lens maybe 35mm or so of similar quality to my other good lenses, and also a macro lens. I'm tempted by the 35mm f2.8 limited macro since it seems like it might do both things. I'm a little skeptical about such a short focal length for a macro though. OT...

advice please on 35mm and/or macro lenses
I don't have the 35mm macro, so can't speak first hand about it, but did go through a similar exercise to you, resulting in the purchase of the 100mm macro. My requirements were different, however, which led to the choice of focal length; I wanted a reasonable working distance between the lens an...

advice please on 35mm and/or macro lenses
summary of what I've read/seen so far is the 35mm f2.8 limited is significantly sharper and has macro, but is more expensive and has less smooth bokeh compared to the f2.4. Since i think i'd mostly use the wider lens for sharp shots i'm tending back to that, i'm pretty happy with my other lenses ...

advice please on 35mm and/or macro lenses
The 35mm macro is a fantastic lens but IŽd say two things. First, take care at infinity because it can focus slightly "off" and require manual over-ride to get it tack-sharp (but it is tack sharp when properly focused). Secondly, the macro function at this focal length is limited in use because yo...

Chipped lens element
If it's a WR lens there surely shouldn't be condensation inside? Or is the pathway for the aperture lever not sealed? Take it back and complain, there is clearly a manufacturing fault.

I'm sending it back for repair. It's only about a month old. Should I accept this or request a replacement?

According to the consumer act. The sale item has to be fit for purpose, if it isn't then you are entitled to a replacement or refund. Don't let the retailer fob you off by telling you that it is a manufacturers problem. They sold it therefore they are responsible. afterall if you bought something of...

Chipped lens element
Hence my post about Pentax QC which got locked As a self confessed fussy person, the lens was not like that when I received it or after my trip to the North East. Took it with me on Sunday for a walk and only noticed it when I got back home to look at my pictures. Was just looking at ...

F* 300 f4.5 or DA * 300 f4?
Anybody able to offer a direct comparison of above? Am aware of the differeces in weight and weathersealing, but how do the different focus mechanisms compare? Davex.

F* 300 f4.5 or DA * 300 f4?
No weather sealing on F* and screw focus compared to SDM (actually faster imo) IQ wise there is very little, if anything in it. F* 880g gets 100% DA* 1160g with hood (F* has built in hood) and gets 9.75% :wink:

Point taken about the 250-600 Mike it's not a hand holder, but certainly usable on a monopod! To be fair it's one of those lenses where you sit and wait for the wildlife to come to you rather than going to find it, as such, as a 'one location' lens there is no issue as you tend to make plans for...

Great shot David. You have chosen wisely. In all honesty it is better than the 170-500mm I have, I tried one at focus and it is faster focusing and sharper. Big thumbs up.

Any advice on Pentax 18-135mm -v- Sigma 18-125mm
I have the Sigma 18-125 but haven't used it for more than a year. It is actually a decent lens with nice IQ and a great walkabout range but of course IQ is not as good as lenses costing x2 x3 more. I have actually had it back in the UK all packed and ready to go for the last 6 months ! However I...

Any advice on Pentax 18-135mm -v- Sigma 18-125mm
Don't underestimate the value of quickshift focussing with the Pentax lenses. The ability to manually tweak focus without trying to find a switch is very nice Pete
