Interceptor121 765 Posted March 5 Those two images are taken with different optics on the same A1 body at similar settings f/11 ISO 100 Which one looks best in your view? There are some little framing differences the second is a cleaner shot as there is nothing behind but just focus on the diver 1 Share this post Link to post Share on other sites
Architeuthis 155 Posted March 5 (edited) My impression is that the first image is sharper and has more contrast. The second one is softer... Wolfgang Edited March 5 by Architeuthis 1 Share this post Link to post Share on other sites
diggy 54 Posted March 5 Without getting into technicalities the second one is more pleasing to the eye. It's also better lit. This is just straight first look. Diggy Share this post Link to post Share on other sites

It is not out of focus the focus point is exactly where it needs to be the images are at 2048 wide but yet it is possible to compare Sent from my iPhone using Tapatalk Edited March 5 by Interceptor121 Share this post Link to post Share on other sites
Interceptor121 765 Posted March 6 (edited) To provide some context Shot1 is Canon 8-15mm with 1.4 TC focal length 21mm Shot 2 is Sony 28-60mm with WWL-1 focal length 28mm equivalent fisheye 20mm The first shot is an adapted lens with a teleconverter this should make it harder to focus, the second is with a native lens with a wet lens. Both are f/11 1/125 ISO 100 As photo the diver in image two looks better she is a small built young diver overall this is better framed and the pool wall behind acts as a reflector In the first photo a bulkier male instructor teaching a student, the background is messy as there are others there but when I took the shot I did not have in mind a comparison and the pool was much busier I do not have a neat shot like the other What I am asking is how the diver looks, not feedback on composition or lighting purely the lens although there are some differences between the images they are minor when it comes to the main subject Edited March 6 by Interceptor121 1 Share this post Link to post Share on other sites

Vive la différence... As to the photo, the lighting is so different between the shots that it makes it difficult to judge as lighting affects contrast and texture and can mae a shot look softer or more crisp. Second shot also does appear to be somewhat out of focus. Perhaps inadequate contrast at focus point to get adequate focus? Share this post Link to post Share on other sites

Second shot also does appear to be somewhat out of focus. Perhaps inadequate contrast at focus point to get adequate focus? The lighting is the same two strobes at the same power the distance is very much the same too one guy is bigger than the girl identical strobe position. One is mid water in the deeper end of the pool the other is on the bottom on the shallow end of the pool. with the female diver the light travels until it bounces on the wall, with the male diver to an extent it bounces on the bottom and then goes through A real demonstration that there is more than strobe positions and camera settings that make the image The second image is in focus the focus point is where it needs to be. Looking at the 50 megapixel images you can clearly see it is in focus However when you scale down to 2048 wide the image of the male diver looks sharper and this for me is simply due to the lens The canon 8-15mm with kenko 1.4 HDX in a dome at the same field of view produces more contrast than the Sony 28-60mm with WWL-1 I did not shoot systematically the first combination to compare as I was looking more for a solution in between the fisheye and the WWL-1 field of view however at the interesecting point it looks like the Canon 8-15mm even with a teleconverter is better Separately I have assessed the issue is the actual lens the Sony 28-60mm is very weak across the edges it is not always obvious but if you focus the camera on a point away from the center the image looks blurry even if technically is in focus From a color rendering perspective instead I would say the Sony looks better vs the canon with kenko but not better compared to the pure canon. the tc is obviously taking away something from the lens 1 Share this post Link to post Share on other sites
Joss 15 Posted March 7 Distorsion of first one does not work for me, I do preffer the 2nd one. Share this post Link to post Share on other sites

JYk 20 Posted March 7 Sorry I think its not possible to answer your question based on both images. I know its hard to do, but for a real comparison, I personal would need a similiar setup. So same diver, perspective and so forth. Otherwise I would pick the second picture. But this could also be influenced by the composition and lightning and not the lens setup. 2 Share this post Link to post Share on other sites
polyroly 6 Posted March 8 (edited) My 2 cents, I agree with JYk. There are too many compositional, lighting and focal 'red herrings' to conclude any meaningful comparison. For instance, one model is rather hairy, their tank has webbing detail and their BCD has a more bold typeface, all could give an impression of contrast/sharpness. The ears appear equal on my monitor as does the corner detail... might you repeat your experiment with a stationary model?
