Tables for 50mm and 135mm lenses assuming it will apply to film and digital cameras

Macro on the cheap (and suggestions for focus rail, please)
Books like "The Asahi Pentax Way" always contained lots of depth of field tables for various lenses. These might be helpful and the books can be found quite readily from second hand booksellers, including eBay, Abebooks and Amazon.

Dragonflies and Butterflies
Some beauties there - I especially like the small copper as it has such an out-of-focus background. Lovely colours too. Nice one! Regards

Dragonflies and Butterflies
Very nice set Gary ! Classic pose for #1 but I really like the Ruddy Darter too. What is the minimum focusing distance for that Sigma ? closest focus : 400cm / 157.4 in. (source : SLR Gear) sorry, the question wasn't directed at me .. :oops: ;) :D _____________________ impressive and usef...

Dragonflies and Butterflies
That lens looks like one heck of a sharp piece of kit Gary. The focus on these shots is stunning and they also seem to have a fair amount of Depth of Field. Some of the best Dragonfly / Butterfly shots I've seen in a while. Regards David

More B/W Beasties
Hello all. Last week I posted some pics I had taken a few years back with my old K10d of various big and small cats, processed into black and white. I really enjoyed going back through them and re-processing so I thought I would do a few more... This time it's birds, again all taken with the Sigma 7...

More B/W Beasties
Thanks again - much appreciated. Frogfish - these shots were all taken at a Falconry centre in the UK where I had gone with a Wildlife photographer (Chris Weston) on a 'photo day' (highly recommended BTW). There were a load of beautiful birds there and kindly some were in more 'natural' surroundings...

Finches at Fairburn
Thanks to all - much food for thought as usual! Alan, I've sent you a message on the back of your Bury station appearance - was it you at Fairburn last Saturday? I remember you posting a shot some time ago of a sparrow hovering next to a feeder - I thought of that when I posted the tree sparrow top...

Pentax mafia.
I look like I'm about to fall over, NO! I hadn't been in the bar, John can't hold his camera level:D So a few more faces to names, Cliff, John and John, who looking at the pics posted so far knew what they were doing with railway photography, not that they gave me any tips as you can see by my ef...

50-135mm + AF1.7x TC
Thanks chaps. The 50-135mm works very well with the 1.7 AF. The focus speed is ultra-quick due to the short throw of the TC focus range. Obviously you need to pull manual focus first and then let the TC snap to final focus. No doubt that on a K5 it will be even quicker. Best regards

Newbie photos with K-R and A 50mm 1.7
Thanks for the replies. Yes it was a pretty dull day, and I was using AV mode, ISO 200, f1.7, not sure about shutter speed. I was using manual focus and catch in focus, but not sure which method was used for the photos I posted. Neil

Went somewhere I hadn't been before ..........
Went off my usual track on saturday to a place where a Kingfisher has been seen quite frequently lately. As luck would have it, it decided not to visit :( Here are some consolation photos I took with the K5 and Sigma 150-500. The blue tit is a bit soft, but it was a fair distance away and very sm...

Went somewhere I hadn't been before ..........
Lovely pictures!! Just a question for you, do you find the focus speed on the K5 faster with the 150-500 than you did with that lens on your Kx ?,that is meaning the actual speed the lens motors from close to infinity. I wondered as the voltage that I've read the K5 battery puts out is 7.2v ,Where...

*flicks hair back and walks away* *I'd be happy to see ONE of those birds on any of my walks* Another lovely set. I did see a flock of Yellowhammers last year - they were very easy to spot by all of the CaNikon big guns lined up shooting them !

Streets of Newcastle
Another vote for 'Three's a crowd'. Funny, I never think of the 50-135mm as "travelling light" :D K. When I see other photographers laden like pack horses with camera bodies clamped to motor drives, heavy back packs and loads of lenses plus a tripod strapped on for good measure I consider myse...
