Bempton Cliffs 30th May 2014
Thanks guys, much appreciated. For what its worth, taking a second look .... the sparrow doesn't look quite right, although I'm very impressed with the detail. Problem was shooting against the sky. LOL at Barrie and the kittiwake. I've got mountains of out of focus fulmars. The flight pat...

Some Recent Macros with a Butchered Zoom
Damn, I knew someone would start asking questions! Like I said, I copied the setup. perhaps Nass will come and answer the technicalities. Charlotte might know more than I. The Nikkor is a very sharp lens. That I know. But I've no doubt you could use different combinations of lenses to do the j...

Some Recent Macros with a Butchered Zoom
I don't hink Nass has actually done this - I got the idea from his thoughts on using a prime lens. The reason you use the reversed lens wide open is that you are using the aperture from the butchered zoom - ie. the reversed lens becomes the front element of the zoom. Stopping down the reversed le...

Some Recent Macros with a Butchered Zoom
Thanks, Charlotte. I'd not quite got the history right. I'd like to see the results of your new experiment. I'll post a few more examples later. I might even go out now and see what I can do. Mind you, my K5 have just developed the mirror slap problem, so it's boxed up ready to go back to S...

Some Recent Macros with a Butchered Zoom
These are superb and by the looks of it no insect was harmed in the process. I only wish I could master this form. Look at the foot detail in #15 - it's his/hers front left - you can see how they hang on upside down. No dead insects. Well, not yet, anyway. If i find a dead one in good condition (if ...

Some Recent Macros with a Butchered Zoom
I'll need to get back to you, dr. I'll do comparisons of the Nikkor on a DFA100 to the butchered zoom setup. But I gae up on the 100 pretty much straight away, as I'd also heard that Charlotte didn't like it. I have no vignetting with the butchered zoom if I stay at 80mm or a little bit less. ...

Some Recent Macros with a Butchered Zoom
There isn't any vignetting on the butchered zoom with the reversed lens wide open at f32 full extension 80mm. It kicks in as soon as you zoom in. I'm sure one of us can try the different zoom lengths and post them with the vignetting. I don't generally crop my photos here's a wasp from today uncrop...

Thanks, that sounds good. I have finished processing my efforts. I'm off to see if I can find an optimal depth of field setting. Now I am making progress with the Nikkor then there can be no going back. Do you have a display of your macros somewhere?

Some Recent Macros with a Butchered Zoom
Just done some tests re above: Got vignetting a bit before you, Charlotte, around 68mm, but only the tiniest whisper. That's probably because I wasn't that clean when removing the plastic on the front of the zoom. I'm quite prepared to say that I could probably see the same results as you if I cl...

Some Recent Macros with a Butchered Zoom
I have concluded my testing. I tried the Nikkor reversed onto the DFA100 and the 77. The Nikkor wide open and the other lens stopped down as much as possible. The 100 works best with the focus set to 0.35m. There is just a little vignetting but the focal distance is a little less than 3cm which ...

These are great images that make me want to go and up my game :) As much as the technical I'd like to know more about your stalking technique, I couldn't get that close to a butterfly in a month of sundays Kind regards Pete A Thanks, Pete. Like I said to smeggy, I only take photos of the...

Some Recent Macros with a Butchered Zoom
Thanks to Neil (darkskies), Charlotte and Adrian (Dr O) for this superb thread. I've now managed to buy a Pentax FA 28-80 F3.5-4.7 and remove all the elements. This was quite a task, unknown to me the 28-80 seems to have a lot more elements than the 35-80 Neil mentioned, and there is no plastic ...

Weekend water
Last week I visited Clifton Lake and lost the slide out piece from my 16-50mm lens hood. So yesterday on the way back from Bunbury, I called to Lake Clifton and spotted the black plastic piece just below the jetty in shallow water. So Mrs K10D was dispatched over the side to retrieve it. Job well...

Bearded Tit
Everything about this image is wonderful and perfect except for the out of focus foreground blade of grass which cuts through the subject and is simply bad luck. I imagine that the lens is not at all easy to use and this augers very well indeed. Good image, nearly much better than that.

Barn Owl
K3 and DA*300mm all taken RAW. I was experimenting a bit with settings but found AF-C with AF-select (expanded Medium) with +1 exposure compensation for shots against sky worked best. For shots against grass/trees I found AF-C spot/center focussing with minus 0.3-1 exposure compensation seemed t...

Thanks for the details, sounds like you work as I do adding/subtracting ev as required, only you're much better at it than me! Also sounds like you are fighting the same issues trying to get the af to lock on when the background is not sky. A couple of weeks ago I was out taking manual focus shots o...

Barn Owl
Most are cropped slightly, I never crop smaller than 6mp (3000x2000) so I know I can get a decent print of at least A4 size. The 300mm does get you close enough, I watched the Owl hunting for a few evenings and noted it's regular route back to it's nest and placed myself on that route and waited,...

Farne Islands 31st May
Thanks Alan. There weren't that many puffins going about with the Sand Eels so you might be OK waiting a while. I took the 1.7x with me and used that with the 300 as needed. I was hampered getting the terns when the 50-135 SDM focus packed in. Pentax SDM lenses are not my favourite just now:evil:...
