jeremy jackson Posted January 16, 2010 Share Posted January 16, 2010 <p>I have posted 3 images at the bottom of my portfolio on photonet. Each image contains 2 images of a scene made with 2 separate camera systems. One of the systems was the Leica S-system with the 70 mm 2.5. The other was made with.....I'll tell you later so as not to bias the ratings. Each of the 3 images represents a specific area/segment of the test shot. Test1 image is a 100% crop of the top left corner of the image. Test2 image is a 100% crop of the left middle and Test3 is a 100% crop of the center of the test image.</p> <p>Both camera systems captured RAW images that were converted using Photoshop. I did not touch either image other than converting it from RAW to TIFF and then to jpeg (I did use Photoshop to convert the non-Leica image to the same size as the Leica image though). Both images were made with a tripod. The Leica image was made at ISO 160, f16 and the other image was made at an equivalent ISO and f16. </p> <p>Pick which side you like best (left or right) in each of the 3 images. Just for fun, report your conclusions in this thread - you can even try to guess what the other system is if you like. In a few days I'll tell you which is the Leica and what the ? system is. You are going to be surprised! NOTE: The Leica is not necessarily on one side or the other in all 3 images.</p> <p> </p> Link to comment Share on other sites More sharing options...
kim-maru Posted January 16, 2010 Share Posted January 16, 2010 <p>Hi Jeremy,<br> My favs are: Left, left, right (ratings of image pairs from far left on my screen to far right).<br> Can't wait to find out what the other system is! : ) kim</p> Link to comment Share on other sites More sharing options...
nathangardner Posted January 17, 2010 Share Posted January 17, 2010 <p>right, left, left...may I ask why you chose ISO 160 and not 100? I read on another board where a guy did a test with a Canon, I don't remember which model, and ISO 160 performed better than ISO 100 because it was closer to the native ISO or something like that. Is this why you chose this ISO, or is it coincidence?</p> Link to comment Share on other sites More sharing options...
jeremy jackson Posted January 17, 2010 Author Share Posted January 17, 2010 <p>I chose ISO 160 because it is the lowest ISO the S-System is capable of. The S-System does have ISO 80 but it's not a real 80. I just wanted the best IQ the S-System was capable of. JJ</p> Link to comment Share on other sites More sharing options...

jeremy jackson Posted January 17, 2010 Author Share Posted January 17, 2010 <p>OK guys, I know you are looking....115 people have looked at the test images, 3 people have rated. If you rate the images here, the results will be a lot more fun.</p> <p>And thanks Kim, Nathan and Stephen for putting yourselves on the line.

bill_tuthill Posted January 18, 2010 Share Posted January 18, 2010 Agreed L L R, although the first L is only marginally better. Link to comment Share on other sites More sharing options...
bruce_t Posted January 18, 2010 Share Posted January 18, 2010 <p>I also think L L R is best.</p> Link to comment Share on other sites More sharing options...
ilkka Posted January 19, 2010 Share Posted January 19, 2010 <p>R L R<br> The first and last pairs confuse a bit because of different magnification, but I tried to imagine the larger image to be the same size as the smaller on the left, and in this case I think R would be better. L looks sharper at first glance, but I think only because it is smaller.</p> Link to comment Share on other sites More sharing options...
krooshof Posted January 19, 2010 Share Posted January 19, 2010 <p>My first impression is L L R. And it's only the first impression that counts anyway when looking at pictures. I think most people would agree on that. Can't wait to find out what the mystery system is. You really know the photo.net psychology, teasing us with this test!</p> Link to comment Share on other sites More sharing options...
thomas_janik Posted January 19, 2010 Share Posted January 19, 2010 <p>1st: L, L, L.<br> 2nd time through: L, L R.<br> I can convince myself of R, L, R as well. <br> I wonder if images 1 and 3 are more of a perception/psychology test rather than a camera system test.<br> Terrific portfolio of images by the way, much better than those in the test :)</p> Link to comment Share on other sites More sharing options...
jeremy jackson Posted January 19, 2010 Author Share Posted January 19, 2010 <p>OK all, here is the verdict. The second camera is a Canon 5D mk2 with the $100 50 1.8. </p> <p>So we have:</p> <p>1) A $27,000 camera vs a $3,000 camera.<br> 2) 37 megapixels vs 21. <br> 3) A sensor that is 50% bigger<br> 4) A $5,000 lens vs a $100 lens</p> <p>Out of 24 ratings, the Canon was selected to be best 16 times. The Canon wins!</p> <p>Now can you pick out which one is the Canon?</p> <p> </p> Link to comment Share on other sites More sharing options...
matthijs Posted January 19, 2010 Share Posted January 19, 2010 Now run Canon or S2 vs the M9... That might be fun. Anyway, great initiative. Link to comment Share on other sites More sharing options...

jeremy jackson Posted January 19, 2010 Author Share Posted January 19, 2010 <p>Scott, we checked the focus on both cameras and all images. Plus, these images were shot at f16 from about 8 feet away. The focus is good. JJ</p> Link to comment Share on other sites More sharing options...
doug herr Posted January 19, 2010 Share Posted January 19, 2010 <p><em><strong>"these images were shot at f16"</strong></em></p> <p>Do I need to comment?</p> Link to comment Share on other sites More sharing options...
scott_ferris Posted January 19, 2010 Share Posted January 19, 2010 <p>Well the fine lines look better resolved on the right on the middle one but the womans face is smoother on the left on the middle one. If I had to guess, I would say the right one for the middle too, but i still think the focus, or something, is off on the middle one.</p> <p>As I said on the similar thread on the EOS forum, these kinds of crop mean next to nothing, <a href="http://www.luminous-landscape.com/reviews/kidding.shtml">even prints can deceive.</a></p> Link to comment Share on other sites More sharing options...
jeremy jackson Posted January 19, 2010 Author Share Posted January 19, 2010 <p>Douglas, I also have images shot at F4 and F11. I am a landscape photographer. F11 and F16 are what I care most about.</p> <p>I assume your post is sarcastic but I'll put the F4 images up if you'd like to try to tell them apart.

scott_ferris Posted January 19, 2010 Share Posted January 19, 2010 <p>My choices were for the ones I thought were the "better" camera, not as you stated halfway down<em> "Now can you pick out which one is the Canon?"</em> . I didn't realise the challenge changed half way down the thread.</p> Link to comment Share on other sites More sharing options...
ilkka Posted January 19, 2010 Share Posted January 19, 2010 <p>No reason for sarcasm. But smallest aperture is rarely if ever a good one. Most short lenses start to get visibly soft around F/11 due to diffraction. 5.6 or 8 is probably ideal for the cheap Canon lens, while the Leica is probably sharpest around 4. This test does prove two things. Cheap normal lenses can be optically very good (at least when stopped down). I have and use a similar lens, but seldom wide open. And the current crop of full frame DSLRs are very, very good. Whether 5D2, A900/850 or D3x.</p> Link to comment Share on other sites More sharing options...
jeremy jackson Posted January 20, 2010 Author Share Posted January 20, 2010 <p>Understand, sorry Scott. I was just being silly for changing the question. I don't know if this helps but the crops are all from the same exposure. So if focus is off on one, it's off on them all.</p> <p> </p> Link to comment Share on other sites More sharing options...
