Break the rules......
It's because your rules are crap :D 1) a good lens is a good lens and a MF lens on APsc is just as good per pixel or per sensor area as it is on MF. It just won't be as good as an equivalent price APsc lens is. 2) yes but a converter doesn't,t degrade MF lenses any more than APsc. 3) and ther...

A.F. Fine Tuning.
Live view is through the sensor so assuming the focus doesn't change from viewing live to pressing the shutter button it should be in focus. Live view is WYSIWYG :D

Mike P, you bin buying primes again???
I already have the 400mm Jules, it was the second lens I bought after the MP-E65mm. Just purchased a EOS-M kit, price has gone through the floor (much like the Q did). 7D sensor in a small mirrorless metal body, that's what the original Q should have been. Just waiting for Photokina now ... Penta...

Which lenses should I take to Santorini in a couple of weeks time?
https://www.pentaxuser.com/review/pentax-xg-1-ultra-zoom-review-841 The trouble with bridge cameras is the quality isn't any better than a good compact, such as the MX-1, and the very long zoom is dim and subject to camera shake. You also still need a camera bag. I'd be inclined to think of th...

New lenses How Exciting!!!
I knew they would start the full frame dreamers dreaming again :D. If and when they do announce a FF no doubt there will be a thread complaining about the price/FPS/sensor/ISO/you name it.:roll::lol:

Looking for lens suggestions Pentax K10D
Hi Chris I think you need to clean the sensor on your camera, loads of dust visible in that shot.

Looking for lens suggestions Pentax K10D
ROFL! I noticed the spots when I uploaded and thought Blimey, I need to clean the laptop screen. Going to clean my camera right now. I have to say Mike, you version of my picture is a vast improvement. Thank you all very much for the advice, just what I wanted Chris - do you know how to clean ...

Looking for lens suggestions Pentax K10D
Make sure it's a rocket blower and give it a few test puffs before you start, to clear any dust out. Hold the camera facing down as you puff, and any dust will fall out rather than in. Don't touch the sensor. Try a few good puffs before using the dust removal system in the camera several times if...

Looking for lens suggestions Pentax K10D
Well. thanks to everyone who contributed to my question. As suggested by Darkmunk I went for a Tamron 70-300 for which I paid £50 second hand (although I've found they are only £70 new on Amazon) The K10D is a splendid thing, but you'll need lots of light as it is not the most sensitive thing. ...

Pentax Forums reviews the Sigma Art 18-35mm
Interesting how it gets slated for poor AF performance; but could that not be down to the camera AF sensor not able to work well with such a wide aperture as the DOF is too low? Pentax make the point that some of the sensors can cope with f2.8 for example and so is 1.8 (and 1.4 for the other art len...

Pentax Forums reviews the Sigma Art 18-35mm
Wonder if there is a difference in focus accuracy between the K5 and the K3, the focus points on the K5 series are some eight times bigger than on say, a Nikon D7100. it may well affect accuracy somewhat? K3 would be a bit nearer the D7100 in that regard, the sheer angle of the light hitting the sen...

Setting 50 1.7 to the k5
I believe you should set it at 50mm as that is its length no matter what the sensor. Of course if you turn the Shake reduction off you won't be asked ohhh myyyy goddddd, its sharp.Just had a quick go of the lens on the K5 and its incredible. One thing though, when the K5 asks you to insert the fo...

tv lens
Many CCTV lenses are CS rather than C mount. Exactly the same thread but a further reduced rear focusing distance. Normal C mount must be ~17.5 mm in front of the sensor for infinty focus, CS reduces this by 5mm. Coverage varies considerably but I don't think any are designed to cover more than a 1...
