ND Grad kits - what to go for
With most things I'd say buy the best you can afford, however, with ND grads I'll take a slightly different route. My anecdotal evidence points to the fact that most folk who buy a set of grads end up using them once or twice before relegating them to the back of the cupboard as they're unwieldy ...

Driving your camera
Can I throw in my four penny worth. As a wearer of varifolcal specs I find using my wifes Olympus compact camera almost impossible to use without tipping my head right back. My brother has a Sony with a rear screen - equally dificult to use for the same reason. My K10D has a viewfinder (I know...

teleconveter on a macro lens
I`ve used the Teleplus MC7 2x on the Pentax A 70-210 Macro, @ 70, which is the macro setting and have obtained very good photos, at about 2.5ft it won`t fill the frame with a Dragonfly, and are very sharp as well.this lens combo is all manual, but you can use the green button,and manual focus which ...

teleconveter on a macro lens
I, too, have been using a kenko 2x converter (MC7), but with my 100 DFA macro. Although I haven't done a like for like comparison, with & without the converter, I don't see much (any?) loss of IQ. I usually use the on-board flash on my K7, with a (plastic milk carton) diffuser, so loss of 2 stops ...

teleconveter on a macro lens
When used for macro, you will double the minimum working distance (the 1:2 will now give 1:1) and the maximum magnification ratio (the 1:1 setting will become 2:1). Almost right. The minium focus distance will stay the same but your focal length is doubled, that's why the magnification is also dou...

teleconveter on a macro lens
No, Stefan is right. A 2x converter will double the magnification from 1:2 to 1:1, for example. The focus distance remains the same, hence the extra magnification. You also lose two stops, so a 50mm f2 lens would become a 100mm f4.

Halogen studio lights
If you want to put the effort in you can make modeling lights for your flashes. Simple lamp holders for light stands are cheap, or clip-on lights from IKEA are even cheaper. You'll need dimmers for each, and a bit of patience to adjust the relative brightness of the modeling lights versus each fla...

The K5 in low light at a wedding
You will get much better atmosphere without flash, so that's a good choice. Don't forget that sometimes swirling dancers with lots of coloured lighting can look pretty good, so maybe don't try to stop the action all the time. The 35mm f2.4 should be quite versatile, just up the ISO setting with c...

Lightroom Update
You're welcome. 8) I spent three frustrating hours on the phone with several techs and a manager to get them to look into the issue. I found it funny because I just had the problem (never tried before), and two days later noticed that the beta out. One of the fixes... the exact same issue but...

Lightroom Update
Yeah, I had actually been going between Pentax and Adobe on the issue. It is interesting to know that if you adjust the color controls at all, the image will still go wildly out of control. This is a separate issue form the Adobe magenta cast problem. It exists even with most programs including...

removing colour cast
You could try using the remove colour cast tool in photoshop or PSE; or, to simply remove magenta tones, you could select the adjust hue/saturation tool, pick 'magentas' and wind back the saturation. Obviously you may need to do some nifty work with layers or similar in the second case if there are ...

I've the Think Tank Retrospective 10 now, it's more then big enough, if i manage the bag a bit better i should be able to fit every lens i have in it plus the flash :shock: So it's bigger then it appears on the inside and that's a good thing! The quality is also great and there are so many pocke...

GPS for Pentax K5, Kr, 645D
FYI, the Nikon version (which is GPS-only) is £199.99 from SRS. So the Pentax one seems pretty reasonable to me! Especially as it'll give you up to 5 minute tracking times using a plain tripod. How much do you reckon an astronomical tracking tripod will set you back?? :shock: Neat! I'll be ...

I knew this would happen and of course everyone has their own preferences depending on their specific interests and capabilities, I have seen some wonderful shots in the gallery and your own websites taken with lenses I wouldn't have thought of but then I am still learning. Unless anything else ch...

Holiday lenses
Well I am back from my summer!!!! holiday in Austria and weather was not what I expected but I suppose you have to expect the unexpected in the mountains. I ended up taking all but the 35mm DA lens with me and for 96% of the pictures used the 18-135mm WR lens. I am not very happy with pictures not...

Infrared with K7
Are you talking about a permanent conversion (ie. replacing the low pass filter with one that blocks visible light)? If so, handholding would be fine. I have a converted k10d and exposure times are on a par with a normal camera. Not sure if the aerial aspect changes things but I wouldn't have tho...

Infrared with K7
Thanks for the reply! Yes I am thinking about a permanent conversion. I go to China with work, Guangzhou, Shanghai and Beijing, so would be very interested in your contact there, and some idea of price.The other option I have considered is selling the K7 and getting a Km to convert. As far as lenses...

Infrared with K7
I've sent you a PM with his details. He usually has some Pentax cameras already converted which may interest you. From my experience I would make sure that any camera you use has focus adjustment available as it makes things much easier. Manually focusing is possible but you need to adjust th...

No problem. Hope he's happy with me sending his details out like this :D I've sent them to quite a few people now. Has anyone actually contacted him and heard back/ordered anything?
