Exposure problems with Irix 15mm lens
I thought I should update this topic which I started in case it has put off prospective buyers! The problem I reported appears to have disappeared. It has not reoccurred for months. I contacted Cameraworld about the original tests and they said to return the lens to them for examination by Irix...

I can't tell anything from your loaded images as they are a very small. My feelings about this lens having owned it for a few months are generally very positive. It has very even sharpness across the frame BUT it is not the sharpest lens I have. In the centre part of the image I think my 18-135mm is...

I've come back for a fresh look. I can see the trouble now (I think). The building on the right looks crap compared to the rest of the image, as in very fuzzy. My first Sigma 10-20 was like that, I sent it back and they replaced it with another that was a much better lens. If this is a constant issu...

The second image is out on the right but not the left so I concur, send it back.

Thanks for the comments. It is the right hand side, and so the bluebell wood - the flowers to right of foreground tree are mushy, from front to back whereas they are sharp in the rest of the frame (and that is stopped down to f8 ). And yes Nigel, that rhs on boat image is awful. I have printed t...

Perhaps you should let them have the camera too and they can check a brick wall out back for themselves. Thanks for the comments.

Hi Jules Stupidly, I only made a note of the last one (although I thought I had noted one of the earlier copies) - wondering if perhaps one might have been recycled! I had wondered whether all my copies were from a duff batch. The second copy I had did get sent back to Johnsons and on to Pentax Fra...

Gallery Help Please
IThought you just uploaded the new one to replace it! i That's what I was trying to do. After I pressed "update photo" (an option I presume is approved by PU, otherwise why give everyone that option?), I pressed "delete photo", and this brings up a yes/no question, that is, do you want to delete ...

Out of focus or blur?
I can't understand if this photo is out of focus or blurred. I can't find the focus plane, but at the same time, if it's blurred, I must have a freaking shaky hand! https://www.flickr.com/gp/sebaslab/TbRo48 please check the original size.

Out of focus or blur?
Nope, i couldnt find it either. Is this repeatable with the lens and settings the same? Perhaps a one-off glitch with the SR ?

Out of focus or blur?
well that would scary me, btw the setting was f/8.0, 1/250. I have another couple of photos of the same series at the same location with the same problem. On other location instead was very sharp. My wife told me I was just too excited :D

Out of focus or blur?
The focus is perhaps on the cheek rather than on the eye, in other words a bit closer than it should be to the camera position. It's a nice shot though, so maybe you could do it again, locking the focus point firmly on the nearest eye. Then a bit of sharpening in Photoshop and it should look very go...

Out of focus or blur?
Looks like a crap lens :shock: or it could be very slight camera shake. The focus is OK especially at f/8 on 88mm. It's actually on the near shoulder, but the wall isn't sharp anywhere and it should be. Do some tests on just the wall. --

Out of focus or blur?
it's the DFA 28-105! I have super sharp photos taken with it, even on that day. This luckily was just a session test, and I am not going to use that lens for the real photoshoot, but if it's a problem with the camera SR, it would piss me off :(

Out of focus or blur?
All I see is a pair of jumping jean clad legs, no eyes and the cheeks I suspect are not those being referred to by others. Then something about ad free browsing. Obviously I'm seeing something different to everyone else. Do I need to subscribe to flikr to view it now?

Out of focus or blur?
Don't forget models move as well as cameras and sometimes even the slightest variation in distance can make a shot softer. Just take lots of images to make sure one is spot on.
