Thank you all for your great feedbacks. It seems that the problem with the panasonic 7-14mm and its purple fringes and haze is quite serious although not completely unsolvable. For 20-30% more, I ...

Hi everyone, I would be very interested to have the feedback of people who have used the panasonic 7-14mm on an olympus camera! My understanding is that there is quite some bad purple fringing and ...

Hi there, I would recommend you to start with the double zoom kit lens that is usually offered as a bundle with the camera. With these two zooms (14-42 + 40-150) you have a wide range of ...

Well actually it is more of a thought experiment rather than for a real magnifier. I was just wondering to which extent aberrations and field curvature could be controlled with a spheres in ...

Thanks for the information. It seems indeed that aspherical magnifiers are rather standard. Can you really flatten the field curvature with aspherical surfaces or does it just help to control ...

Just wanted to thank you all who contributed to this thread, it is very much appreciated. I have read carefully your reply and I think I understand the differences between DOF and infinity ...

Hi everyone, I have been interested in the history of camera lenses lately and read a few things about Wollaston, Petzval or Dallmeyer lenses among others. I also read a few things about magnifying ...

Hi, I would say you should buy a entry level DSLR with its kit lens and add a cheap fast prime lens (50mm f/1.8 or 35mm f/1.8). The entry level DSLR will be a great first camera you can evolve with ...

Hi there, I have also been experimenting with landscape astrophotography. It is quite possible to achieve interesting results with a wide prime (12mm f/2 or the 7.5mm F73.5) and a clear sky. The ...

Thanks peter. I actually think this is my preferred picture. I had not really noticed the black object near lower left before (it is actually a tree) but now that you pointed at it, I indeed think ...

Hi everyone, It has been snowing at quite low altitude last night and there was some snow in the Lavaux vineyard along the lake of geneva. It makes quite a few interesting geometric patterns. C&C ...

Hi everyone, It is common belief that short focal length lenses have greater depth of field than do long lenses. However, if the subject distance is changed adapted with the different focal lengts, ...

This unfortunately does not work. At least it does not work if the file is already uploaded in lightroom. Maybe the changes in the preferences has to be done before the import. I'll try to delete ...

I am afraid it does not work with my version of lightroom 5.6. Whatever the option of aspect ratio I am selecting gives only a crop of the 16:9 image but does not retrieve the initial 4:3 raw ...

Thanks Ido, it is good to know that the 4:3 image is not lost. I just need to figure out how to retrieve it in lightroom. If I do not find a way, I will indeed go to an other raw converter as you ...

Thanks Dick, I think Lightroom somehow merges the jpeg and raw files in one. As soon as I find some time, I will try to display the jpeg and raw as a separate image and see if I can retrieve the ...

Hi everyone, just a short question. I have just had a photo session where I have been shooting raw + jpeg with my Em5. The final image should be with a 16:9 aspect ratio so I have set the camera ...

It would indeed be interesting to have a comparison between the two 40-150mm (the 40-150 pro vs the 40-150 standard) when the 40-150mm standard is fully extended. That would show us how much ...

Yes you have a good point. Actually he really likes to take pictures a lot and always looks for original compositions and nice angles. Therefore, I thinks he would not be happy with a Rebel body. ...

Yes you are most probably right that the output of the Rebel T5i would probably be very close or just as good as with the 70D. The process of taking the picture is completely different though. ...
