ebay:New DA 300mm f/4 £659.99!!!
Amin - I loved Tanzania! I was so impressed with everyone there. Their ability to live in harmony irrespective of race or religion, and their desire to learn and improve themselves was truly an eye opener. So often you get this depressing view of Africa, not only of starvation but also of corruption...

Night Photography.
There are some dangers associated with night photography. I took the image below, tonight, on a fly-over near Falkirk, Scotland, where there are 'on / off' ramps, and I thought they would add to the picture. The amount of abuse and honking horns I got was unbelievable!!! One guy even stop...

vario macro lens
Has anybody seen or used one of these? I have been loaned this one. It is a M42 screw mount with a fixed focus, that appears to be 160mm from the sensor on the K20d, leaving a working distance of around 100mm. The image below was taken with the lens set to f4. Hopefully the weather w...

vario macro lens
I've no experience of that particular model but lenses lacking a focus mechanism are designed to be used with a set of bellows - you find the focus point by moving the bellows in and out. No reason to suppose it shouldn't be an excellent performer, dedicated macro lenses generally are. :D

vario macro lens
I have just used it with an M42 adapter direct to the camera and with some extension tubes, moving the camera to focus.

50mm A 1.7mm
Thanks for the info. SHould I be inputting the 35mm equivalent, or just putting in 50mm. Reason I ask is that although it "tells" me when it is infocus with the hexagon, I have taken a few pictures of a focus chart and I would say it is front focussing by about 10mm, which is way no good when you ...

50mm A 1.7mm
No. You'll get super results from the 50mm once you've got the hang of it. Treat the green hexagon as a rough guide only. You can actually often focus more precisely by judging by eye. Failing that, take several shots with several slight adjustments of focus. If you want to get more seriously in...

Jessops to close 17 stores
Back at the end of 2007 they closed over 80 stores and since then odd ones and twos have been disappearing. At one time I believe they had 350 or so ...

55mm ??
Hi All SRS sent me an e-mail Monday, got back to them Tuesday and my DA*55 arrived this morning (Wednesday) just as I was leaving for work. Excellent service as always. Cameras not allowed in work so I've only been able to take a few wallpaper shots at home with flash this evening. First im...

55mm ??
The review agrees with Tyr, focus off with the K10D and purple fringing wide open. Focus ok with other bodies though (how odd...). Cheers, Kris.

55mm ??
I'm still wandering if to get it or not over the FA 50. It's so far as I can see quite a bit sharper wide open and the bokeh is pleasant to my eyes atleast so nothing against the image quality besides the purple fringing wide open but I can live with that. The focus thing is another matter. For ...

pentax 100 2.8 smc dfa VS sigma 105 2.8
The Sigma is very good but if money is not an issue I would take the Pentax over it just for the quick shift focus. To be honest I have never seen a bad macro lens.

pentax 100 2.8 smc dfa VS sigma 105 2.8
Virtually all of my lenses are Pentax but I did select the Sigma in preference to the Pentax after an exhaustive study of the two. My Sigma stays permanently on manual focus.

pentax 100 2.8 smc dfa VS sigma 105 2.8
Thanks for all your quick responses. The Quick Shift is something that is very tempting. Has anyone noticed the lens hunting for focus. Some reviews have mentioned it hunts quite a bit and the Sigma does not because of the focus limiter. Anyone experienced this? I guess it could be limiter vs qu...

pentax 100 2.8 smc dfa VS sigma 105 2.8
. . . Has anyone noticed the lens hunting for focus . . . Hunting will always be an issue with any AF macro lens when used in AF. For that reason, most macro lens users prefer manual focus. AF in macro is a hindrance, not a benefit.

55mm F1.4 DA *
I was only joking...I'm only 36 and I do remember these :lol:. I suppose you could say they were the forerunners to the Clubcard & Nectar card schemes? Back to the OP with this lens out does this mean that the long awaited 60-250mm is just around the corner? Rob

50-135mm DA*
Has anyone had a problem with this lens? I was doing some publicity shoots on Thursday and put this lens on the K20D. Problems I was having was that the lens would not focus at all, whether in AF or MF. After taking the lens off and on the camera many times, I would focus, but the images were...

Conclusions with thepentax 55-300 mm
Had a field day yesterday with this one as the sky decided to turn blue for the day. A few conclusions I have come more about my own inexperience in the field rather than the lens itself are the following: I realised after coming home and processing the images that I might be shooting at subje...
