For example all dkl, asahiflex and topcor lenses were aquired relatively recently, and I haven't shot enough with them yet, nor done the formal tests (brickwalls and such) yet. Hopefully I will have time this comming summer to catch up with that. It is hard in winter when the sun here is not up when I go to work, and it is down again when I return from work...Douglas_of_Swedenhttps://www.blogger.com/profile/03610361457048882192noreply@blogger.comtag:blogger.com,1999:blog-7826160928979421619.post-80873195078521387682015-03-17T05:31:32.458+01:002015-03-17T05:31:32.458+01:00Using your [5*] ratings to add you my collection. ...Using your [5*] ratings to add you my collection.

It behaves (in terms of image angle) as how a 35mm (or to be more precise a 36mm) lens would behave on a full frame or 35mm film camera.

I understand it...Thank you for your comment Kamran. I understand it as you want to say that my whish for sensor based image stabilizatoin on the Samsung NX does not apply because I use old mechanical lenses with adapter. This isn't correct, thought I can understand that you arrive to that conclusion if you experience is limited to Sony. Pentax allow image stabilization for any lens, however old and non-electronic it may be. As soon as the camera conclude that you have mounted a lens without electronic info on the focal length, it prompt you to enter the focal length on the display (you simple swap through a long list of clasical focal lengths and pick the nearest...it goes quite rapidly). This works the same way on both Pentax DSLR and Pentax mirror-less cameras (K-01 and Q). This is what I wished for on the Samsung NX. Why Sony doesn't offer the same possibility on their cameras I don't know. But a guess would be that it is simply true as people say that Pentax are very concerned with comming up with user-friendly solutions, especially to please the enthusiasts, and very good at tweaking different functions one step further than the competition.Douglas_of_Swedenhttps://www.blogger.com/profile/03610361457048882192noreply@blogger.comtag:blogger.com,1999:blog-7826160928979421619.post-85729840058736267422014-01-30T06:09:29.949+01:002014-01-30T06:09:29.949+01:00In order for the In Body Image Stabilization to wo...In order for the In Body Image Stabilization to work, Lenses need to have electronic contacts which communicate with the camera so that it knows on what focal length you are working on. Unfortunately, this is not the case when you mount legacy glass on mirrorless bodies.

I agree about the shutter and the mirror should cover the sensor that is 16x24 so it would fill at least 24mm in each direction not 16mm as in your draw. ;) <br />Thus I believe the mirrorless cannot be thicker than 3cm or little more (not so bad anyway). <br />I'm a little sceptical they could use this concept mainly because a mirror placed before the sensor isn't the best for optics (problem with the rays' angles if lens not telecentric, a little loss in EV, ecc.). <br />Anyway, till CP+, who knows.. :)Chelidonhttp://www.pentaxforums.com/forums/members/41004-chelidon/noreply@blogger.comtag:blogger.com,1999:blog-7826160928979421619.post-37829089497578420072011-12-27T15:32:58.365+01:002011-12-27T15:32:58.365+01:00Perhaps like the Panasonic Lumix DMC-TS2, a prism ...Perhaps like the Panasonic Lumix DMC-TS2, a prism can be used in lieu of the mirror?<br /><br />That's how they managed to keep the lens inside the camera body and still provide a zoom (the camera is waterproof).<br /><br />pproPaul M.

Since the mirror doesn't have to flip you can move in a few mm forward, further reducing the depth of the camera.<br />2. I think the shutter is better placed in front of the shutter, to reduce the risk of damage - dust on the mirror doesn't seem to be a problem for the Sony SLT-A55.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7826160928979421619.post-40083489196460282382011-01-29T11:08:04.572+01:002011-01-29T11:08:04.572+01:00great idea! than you can keep the (phase) focusing...great idea! than you can keep the (phase) focusing under the mirror (maybe lose some small part of the light for that cause)hrvoje_filahttp://www.flickr.com/photos/47391781@N04/noreply@blogger.comtag:blogger.com,1999:blog-7826160928979421619.post-51294132917822175822010-08-03T22:32:34.947+02:002010-08-03T22:32:34.947+02:00Glad you like them!Glad you like them!Douglas_of_Swedenhttps://www.blogger.com/profile/03610361457048882192noreply@blogger.comtag:blogger.com,1999:blog-7826160928979421619.post-14165436374273834382010-06-11T21:24:42.205+02:002010-06-11T21:24:42.205+02:00I love your pictures!I love your pictures!Hanne, DKnoreply@blogger.comtag:blogger.com,1999:blog-7826160928979421619.post-23800886130174004332010-02-19T15:29:28.647+01:002010-02-19T15:29:28.647+01:00Very nice.
