Unsure if still available in England as I just got my copy of the April issue of "Photography Monthly" in Canada and features a review of GX -10, and didn't like the KIT lens as I just did a quick scan when reading your post. I use the Pentax *istDL2 with the 18-55 and 50-200 in RAW a...

I had problems with getting manual focus exactly right. So bought a split screen See post https://www.pentaxuser.com/forum/viewtopic.php?t=4018&highlight= If you use MF on the K10D with any screen you will get a confirmation light in the viewfiinder when correctly focused. :wink:

DSLR Advice

All Pentax AF cameras provide focus confirmation with any manual lens, provided there is sufficient light for the AF sensor to operate. I've never tried, but I would presume it would also work with a black cat in a coal cellar provided the camera or flash unit had a focus beam. G

All Pentax AF cameras provide focus confirmation with any manual lens, provided there is sufficient light for the AF sensor to operate. G I can even get that with an f8 mirror lens (most of the time) in good light and with enough contrast, (that being the key to AF afterall) which is way past th...

DSLR Advice

Hi UIS.. ;) I must get some filters for mine as well. Maybe the same choice as you. Does anyone know of a good make to go for. I am a bit out of touch with whats available. Go for Cokin.. or Lee when you win the pools.. :) The advantage of a system like Cokin, is that when you add a new lens ...

Dummy question on istDL2 from a newbie

Welcome to the board :) The sequence was something like this: *ist-D, *ist-DS, *ist-DL (and the "2" versions followed though I'm not sure in what order - some of this was down to market areas). The DL has only three AF points. I believe you can choose to select the centre only throug...

Question about mega pixels and printing

All this "who needs A2 printing anyway" stuff is fine if you use the whole frame. But assuming that a) sharpness of the lens is not limiting, b) you can get the damn thing in focus anyway (not always the case) and c) noise is not an issue, any time you need to crop and enlarge, the more...

Banding Not Exclusive to PENTAX...Canon 5D!

Just Copied this from e Photozine. It seems that the apparent problem with the K10D is not exclusive to PENTAX: Quote: Hi, I have had terrible problems with chronic lining/banding appearing on images across all isos. I sent my camera back to Canon U.K. 3 tmes each time coming back with same p...

3 different cameras sharpness and image quality test ???

For the choice for Pentax came out of a number of reasons. 1) I had previous good experience with them 2) The handling and overall "feel" of the camera 3) I had very bad experience with Canon (dead USM motors) 4) absolutely no experience with Nikon Allthough the camera could have ...

First Image Attempt using HDR in photoshop UPDATED IMAGE

Hi Chris Yes I noticed the flowers didnt quite show focus or sharpness. This maybe to do with PS merging the 3 images and trying to automatically aline them together. I will check all three. It may have been slight breeze or if I remember I did focus on the tree with the camera. Also could it be ...

First Image Attempt using HDR in photoshop UPDATED IMAGE

Quick update all three image appear a bit out of focus on the flowers so it must be slight movement. If ALL the images show out of focus flowers, it's unlikely to be movement of the subject unless your shutter speeds were very slow, and you didn't say what these were. The reason I asked was b...

First Image Attempt using HDR in photoshop UPDATED IMAGE

Pete, good first try, but as Chris pointed out there are some weaknesses. One thing that hasn't been mentioned is the halos around the tree trunk. There are lighter areas directly next to the tree that don't make sense. I also had a go at the technique a while back, here are original (i.e. strai...

First Image Attempt using HDR in photoshop UPDATED IMAGE

Just my penny's worth... * For true HDR you must take multiple exposures - you can't take a single RAW and process three times. However, that technique has its place - but it won't work for HDR because there simply isn't enough dynamic range even in a single RAW file ;) * The HDR process is sp...

First Image Attempt using HDR in photoshop UPDATED IMAGE

I see what you mean but would rephrase/clarify a couple of points. * It seems to me that you are implying that the noise floor is sufficiently high that the bottom several bits of a 22bit file would essentially be too noisy to use anyway. I can well believe this. * In 24bit audio actually I ha...

First Image Attempt using HDR in photoshop UPDATED IMAGE

there must be a time factor involved too. 80,000 photons over what time period? you could reset the sensor and then keep counting from 1 again to up the total. EDIT - i've just read that wiki, to do the above you'd need an interline sensor rather than the always on sensor and mechanical shutter o...

First Image Attempt using HDR in photoshop UPDATED IMAGE

Hi All This is a similar image using 4 images taken at different exposures. It seems to have better focus on the flowers and the sun is more pleasing to the eye. The composition is not as good though. See what you think

It seems to have better focus on the flowers and the sun is more pleasing to the eye. The composition is not as good though. Agreed. You can crop it to get much the same view as the original though. It's the left hand side that's rubbish in this one.
