k5 video and lens aperture
Sometimes I wish that the centre of the Live View image was blown up to 4x for focus checking while in video shooting mode my thoughts exactly

you can set it to zoom in when focussing and then start the shot...that's why follow focuses have white skirts to mark focus points..... Bret

you can set it to zoom in when focussing and then start the shot Thanks Bret I always do that it is the subsequent refocussing that is the problem.I do like the idea of the Loupe though,will try to find a decent one and give it a try,would also be useful for liveview macro focus

no, it won't, because the resolution of the rear screen becomes the limiting factor and it's only 920k dots. So that's 300k pix - meaning we're talking about 200x150 real life res. Which is pathetic. Alternative? arm and 10" TFT in native 1024x576 res (set the HDMI output in the menus to 576p). M...

k5 video and lens aperture
I disagree based on practice; focus gets far more critical with Video because you regularly shoot as wide as the lens will go, meaning you have a front of eye in focus and not the back. You also have the unfortunate problem of your viewers expecting a *lot* more from video than stills. If you want ...

k5 video and lens aperture
This is probably fair if you are expecting Kubrick-quality from your video shooting! However I doubt the f4 lens Roy is talking about is of such shallow DOF that you could tell whether both eyes are in focus let alone the front and back of someone's eye... The subject's face being acceptably in focu...

I disagree based on practice; focus gets far more critical with Video because you regularly shoot as wide as the lens will go, meaning you have a front of eye in focus and not the back. With wider focus length you often have less magnification so more DOF right??? Also since the video is a dynamic ...

You mean the close up shot at the 15 second mark? DOF depends largely on the magnification not so much the focal length like most think, so if you've 1:1 magnification the DOF is almost just as great with a 50mm lens as with a 200mm lens. The DOF can even be wider with the 200mm lens as with the 5...

it's a canon 17-55, no close focus, so there's nowhere near 1:1; max magnification according to the stats is 0,17. Bret

K-5 Anti Shake
Hi folks :) I've always left the Anti-Shake on my K-5s. For a while now I've noticed some pics blurred even though I Know focus is spot on and shutter speed is very fast. 1/1000 or over. I've now sussed out why .... A lot of my shooting style is "See it, Autofocus it and snap it" - however ...

K-5 Anti Shake
SR mechanisms are fine when the camera is intended to be held still and the subject is still. They don't help at all with rapidly moving objects, panning, and probably much of sports photography. Even a simple picture of a flower, which may be moving in the wind, can be an action photograph. W...

You can't apply the same rule of thumb to everybody :shock: as you get older you need to use a faster speed :oops: 20 years ago I used to regularly use 1/8th second with 6x6 on weddings (candlelight. church interiors etc. ) nowdays I don't think I could go below /100th although I haven't noticed muc...

[quote:3496ace15f="johnwhit"]I'd like a firmware update to manually override SR settings so I could set in a multiplier for SR, 4 options in the menu 1.4x, 1.5x, 1.7x and 2x. That should cover all TC's in use and optimise SR for the focal length actually in use:shock: John Why not just the option...

An interesting read. I've had a K-5 since last November [the original one swapped for new a couple of months ago when it developed a sensor stain plus another minor problem] - my last Pentax was a K-20D in 2008. I returned to Nikon at the end of 2008 when the D90 came out and changed to the D300s wh...

Curious that no mention was made of older lenses, either Pentax or 3rd party, as there are a plethora of really long lenses that will fit given a suitable (and often cheap) adapter will find an extended life. My own longest is a Tamron 500mm mirror from 35mm days. regards Bernard Indeed, is that...

The main problem I have is the lack of a fast focussing zoom that goes to 300mm and competes with the Nikkor 70-300 AF-S. The Pentax 55-300 is optically very good - in the kit form is fantastic value given the results - but just so noisy and slow when it loses focus. We could do with a Tamron AF 70...

Only snag then is that the more clueless reviewers (like the one who thought the chrome trim on the K-m was more important than the images it can produce) will whine that it doesn't have a zoom lens! :lol: I do think Pentax should offer both as kits. Go back to boxing bodies and lenses separately...

The reviewer did not mention the flash systems. I shoot Pentax and Nikon. I find them so close in operations as not to be an issue. Best IQ ??? Pentax. Best current lens range, AF and flash ??? Nikon. Only tools at the end of the day. Best regards Actually I think he did mention the ...
