Filters for the Bigma
...this Bigma has such a big front element i am worried something is going to hit it eventually. But in saying that the hood gives it pretty good protection so maybe i am being a bit paranoid. Just keep the hood on. If you think about it, if there was a filter on there, anything that might damage t...

Filters for the Bigma
The real worrying thing about salt is the fine spray you can feel on your face but not really see, as this can get into the camera and lens and cause internal corrosion. Back in the early eighties a friend of mine took some great pics on a cruise ship during a gale. he cleaned the camera carefully a...

Sima 100-300 F4 EX
I got a 100-300mm EX F4 second hand and soon got rid of my 80-320 Pentax, the Sigma is a very good lens but just a bit heavy for a walk-about lens. I do mainly wildlife photography and have found the auto-focus a little noisy so have a DA* 300mm F4 pre-ordered. I will be keeping the 100-300 Sigma t...

Sima 100-300 F4 EX
Had a quick go on the Sigma at the weekend... It's very big, and heavy(ish). Wasn't too bad using hand held in sunset light on the K10D with a grip and SR. Like all the Sigma EX lenses, it's well built, and the image quality is excellent too! Focus is quick and quiet too :) As has been said, it'...

K mount 300mm (K, M, A or F but not FA or Digital) wanted
Going on Tiger Safari and need something big, fast or reasonably fast and not too heavy. In ideal world would want to rent/borrow 300mm F2.8 ED for 2 weeks, however it looks like will have to settle for something less. I think 500mm F4 is just too long and unwieldly on back of jeep or elephant. ...

K mount 300mm (K, M, A or F but not FA or Digital) wanted
My wife and I went to Ranthambhore (another Tiger reserve in India) over the Xmas holiday. I used an M*300/4 and my wife used an F 70-210 (both on digital). My experience was: The F70-210 is a great lens but was not quite long enough and the 300 was much better (although a lot heavier to lu...

K mount 300mm (K, M, A or F but not FA or Digital) wanted
I used a shoulder-pod to keep the 300 steady, but I'd wished I'd taken one of those pods that attaches to a car door - would have been perfect for using in a jeep (but not so good from the back of an elephant :)). R Take an empty beanbag and fill it up with rice locally - makes a great car door sup...

K mount 300mm (K, M, A or F but not FA or Digital) wanted
I used to have the K 300mm f4. Super image quality, but heavy, and slow to focus. I was using it in East Africa, and didn't get many memorable pictures from it because it wasn't the easiest lens to use. Although you say you don't want an F or FA lens, the F 300 f4.5 is a superb, compact, lens, ...

K mount 300mm (K, M, A or F but not FA or Digital) wanted
Well, now back from India and have 10 rolls of film to be processed as well as 2 memory cards worth of pictures from a Fuji and a Nikon digital compact. Results: - bought a Manfrotto monopod, worth its weight in gold, many people had big lenses and were relying on image stabilisers to get good sh...

K mount 300mm (K, M, A or F but not FA or Digital) wanted
The F and FA lenses work well in continuous focus, and will allow you to shoot birds in flight very effectively. I would rate an AF 300mm as much more useful than an MF version. G

Porst 55/1.2
Hi and welcome! Niblue has one of those, I guess, and he seems to like it. Nevertheless, the Pentax-K 50mm F/1.2 is going for very affordable prices on the Bay. I sold mine a couple of months ago for less than that value (and now I kind of regret it... but the money for the 77mm had to come from ...

Sigma 18-50 ex - problems! with focusing
Hi All Sage Ones, I bought a Sigma 18-50 EX DG (do you ever wish they were just called Dave) from ebay for my K10. This is not the new macro version. And on tests I keep getting a focus problem. The lens seems to be focusing behind the the subject. Through the view finder it seems to focus ...

Sigma 18-50 ex - problems! with focusing
Which camera? The only reason I ask is that my K10D had consistent back-focus on all lenses ;) I see from your signature that you have the *ist-D - try it on that as well. The wider the aperture, the more critical focus becomes! There's some info here: https://www.pentaxuser.com/forum/viewto...

The limit switch will stop the lens hunting all the way out to infinity and back when doing close up work.

You did well for £50 :shock: Full = focus all the way from infinity to macro Limit = either infinity to 1m (ish) or 1m to macro. If you're using the lens as a fast telephoto, setting it to "Limit" will help with focus speed. It will hunt far less. If you have it on "Full" ...

you got the AF version for £50? I am SO jealous! Hope you grow to love it, my older Tamron SP F2.5 90mm manual focus version has yet to let me down and the newer ones are reputed to be at least as good.

Pentax A-50mm / f1:1.4
Galoot, Can't work out the f/1.4... but the DoF will be incredibly shallow. At 2m it is pretty unforgiving :roll: Personally, I found I messed up the SMC-A a lot... turned out it was mostly because I was using the red dot as a focus aid. Doh! Should use the green octagon at the bottom of the vie...

Pentax A-50mm / f1:1.4
Looks like a focusing problem to me. The number on the side of the red boat is nearly in focus. You said it was quite dark and this may be the reason for the error. Now, if we had split screen focusing like in the good old days, this probably wouldn't happen.
