Best air blower for camera?
Going back to original question, I don't think its a good idea to use a blower into the camera with the lens off is it? I think you're more likely to blow dust into the camera. I would suggest not worrying about dust getting in - just change the lens indoors and point the camera downwards while the...

Best air blower for camera?
Normally, when I change lenses, the shutter is shut over sensor ... quite! I've never bothered about which way up the sensor is facing and I've never wet cleaned the K20 or the Q, the built in sensor shaking seems to do the job for me. However, getting back to the original question, the Giotto...

High & Dry Customer Service
Thought I would share this with other members. I sent a DA*55 off to Johnson’s for repair in late June of this year and Johnson’s informed me that they would have to send the lens to France for repair. Well the days and weeks rolled on and despite contacting them to find out the status of the repai...

High & Dry Customer Service
I can sympathise I do hope this is an exception to the rule but I fear it may be not be. These days many big multi national and national companies seem to be more interested in profit and don't value customer loyalty. I suggest you write registered post to the highest person at Pentax you can find ...

Why we don't need FF
When I bought my *istD body I only had 35mm format lenses. All of a sudden my wide angle lenses were crippled. Indeed, for several years I was under the impression of why should I have to buy new glass just to get back to where I was with 35mm format. I finally gave in and decided that if I ha...

Why we don't need FF
A few years ago there was a lot to be said for the bigger is better argument but advances in sensor design and processing mean that even very small sensors such as that in the MX-1 (sorry to bang on about this camera again, it's not as if I'm obsessed or anything) can produce images of a quality uni...

Why we don't need FF
I think it was Einstein who said 'If you need to look at Youtube to see if you need a FF Camera..... Then You don't need a FF Camera' :mrgreen: :wink: Of course if you shoot birds you will already know that FF isn't the correct tool to use :lol: You do don't you! :shock: https://www.youtube.co...

Pentax Camera Image Controls vs Computer Editing
I wanted to lay down some thoughts on the recurring theme of 'in-camera' capture and computer image editing. It would be good to set out some goalposts and try and establish some common understanding for these debates, as I feel they are often confused by misunderstanding, termonologies and people a...

.... Like I say, I'm not looking to derail this conversation with the 1 hour lab comment, .... :D No worries Richard, frankly these sort of debates tend to take on a life of their own .... certainly I, as the instigator, usually find it's hard to keep the troops in line! :) Look, already just abov...

Pentax Camera Image Controls vs Computer Editing
Hi petro, good to have you joining in :) The division I'm defining here between 'input' and 'output' is really based on whether the particular control or function is a 'physical' or optical function (like aperture, time value, focus) or a quality 'burned' in to the sensor data (like ISO) ... these ...

Pentax Camera Image Controls vs Computer Editing
I'm looking at ISO as being a setting that 'burns in' certain IQ characteristics at point of capture - noise levels being the most obvious, but there are tonal and colour changes at higher ISO's also. I see it as in the same category as aperture, time value, focus and flash lighting because it has n...

Pentax Camera Image Controls vs Computer Editing
HDR is often used for excessive effects, but for severe dynamic range, such as church interiors, it can be used to deliver impressive, natural looking images with full detail throughout. Interesting comment! Do you remember ? The concensus conclusion, which included the HDR evangelist who ...

Pentax Camera Image Controls vs Computer Editing
Have you tried this Andrew https://www.pentaxuser.com/forum/topic/newcastle------again-----51425#comm542413 The images in that thread use HDR and look very nice - but, without a direct A-B comparison between the HDR version and one that was optimally processed, but without HDR, it is not possible to...

:D Well I did say this sort of thread can go any which way! All interesting stuff chaps ... I did think you were asking for it John, in telling Andrew that HDR was good for churches ! :mrgreen: In fairness, I'm hardly the most committed HDR evangelist ... I too have not fired up Photomatix latel...

Monitor calibration devices - something fairly good, straightforward & not too expensive?
Hi John, I use X-rites's ColorMunki Display. I found that my monitor was not in agreement with photos coming back from the printers and since calibrating with this thing all has been well. When first using it, you'll go through a calibration sequence after which it is left connected with a smal...

action dog photography
Aperture priority, using a wide aperture, ISO say at 3200, better at 1600 if possible, using single shot and anticipating the action. Manual focus would do this, just prefocus on the track and release the shutter just before the subject arrives at the required spot. There's always a slight reaction/...

action dog photography
Thanks John, I'm really not sure I can nail the shot in one tbh, I'm stood bout 75 feet from start gate and by time the dogs get to my spot there doing nearly 40mph. I did wonder if a smaller f stop say f8 might have helped keep more of the dogs in focus but, with the light on sat it seemed to...
