osera Posted January 8, 2007 Share #1  Posted January 8, 2007 Advertisement (gone after registration) OK, first of all, if you dislike test shots, stop reading and stop looking right now. You won't like this.  Secondly, this is just a quick test, not a detailed scientific, professional "Sean R." kind of analysis. Just some pictures on a sunny day. This location chosen for its small details.  So here's where these come from. I have the 16,18,21 tri-elmar. I also have a 21/2.8 ASPH. These images are with the TE at 21, camera on tripod with no change in tripod position, iso 160, manual metering in camera. (I'm sure I could have done a little better with the exposure.) I made images at f4 (max aperture on TE), f8, and f16. There was no filters on these, as it's not really an option for the TE at this time (and that will involve other issues, of course.) Both lenses are coded, and lens detection was enabled.  Raw images processed in C1, color balancing with a whibal. I have included some sharpening in C1.  No additional processing in PS, except sRGB, downsizing, and the detail crops.  Here are the f16 images. All are shown with the 21/2.8 above and the TE below.

Advertisement Posted January 8, 2007 Posted January 8, 2007 Hi osera, Take a look here New tri-elmar and 21/2.8 side-by-side on M8. I'm sure you'll find what you were looking for!
osera Posted January 8, 2007 Author Share #2  Posted January 8, 2007 Here's the center and the upper right corner.  21 above, tri-elmar below. Welcome, dear visitor!

osera Posted January 8, 2007 Author Share #3  Posted January 8, 2007 Sorry for all the images, but here's one more corner, the lower right. This is the closer corner.  (Do the corners matter???)   21 above, TE below. Welcome, dear visitor!

marknorton Posted January 8, 2007 Share #4 Â Posted January 8, 2007 That wall on the right, is it flat or curved? Link to post Share on other sites More sharing options...
osera Posted January 8, 2007 Author Share #5  Posted January 8, 2007 Mark-  Good point. It is in fact curved. Here's a shot from further back. Does the curve of that wall come through?

Englander Posted January 8, 2007 Share #6 Â Posted January 8, 2007 Allen, Thank you for posting these shots. Many of us are interested in the comparison. Â Other than slight differences in exposure, on my monitor I can see very little difference; perhaps those with newer and bigger displays can discern differences. Would you be kind enough to comment on what you see, especially at more moderate apertures such as f/8? What about distortion of straight lines such as showed up in Erwin's WTE samples? Thank you, Joe Link to post Share on other sites More sharing options...
marknorton Posted January 8, 2007 Share #7 Â Posted January 8, 2007 Advertisement (gone after registration) I'm pleased to see the wall is curved, otherwise the distortion looked horrendous... It would be very interesting to see shots at 16mm from the same position plus of course both lenses at f4. Link to post Share on other sites More sharing options...
marknorton Posted January 8, 2007 Share #8 Â Posted January 8, 2007 Interesting too to see the benefit which will come with the spirit level in the new finder. In these images, the camera is tilted slightly back and you have diverging verticals! Link to post Share on other sites More sharing options...
c6gowin Posted January 8, 2007 Share #9 Â Posted January 8, 2007 Allen, thank you for posting these comparison shots. Sharpness and distortion looks comparable between the lenses based on the web samples posted. I would be curious what your thoughts/conclusions based on your comparison viewing full resolution files.

DaveEP Posted January 8, 2007 Share #10 Â Posted January 8, 2007 Interesting shots - thanks for posting these. It makes the WATE more interesting, because I rarely to much low light stuff at wide angles. It would be interesting to know how the WATE compares to the C/V15 too.

osera Posted January 8, 2007 Author Share #11 Â Posted January 8, 2007 Thanks for the nice comments. Â I'm still reviewing the full images, but there are a couple things I've noticed. Â I think that the 21/2.8 is slightly sharper in the center than the TE, but I cannot detect a difference in the corners on my shots. The f/8 and f/4 images show the same, although a bit trickier in the corners here because the lower corners are closer, and so are just a bit out of the depth of field as the lenses are opened. I think I'm starting to inadvertently "test" DOF with the other images, so I started with posting the f/16 for now. FWIW, I printed some of these samples on Epson Enhanced Matte on a 7800, I cannot see a difference in "sharpness" on the prints. Â The color is close but very slightly different to my eye, but that's hard to see here, partly because of the web and partly because I think the exposure is slightly different. Â The TE has a slightly wider FOV at 21 than the 21/2.8. Not sure what that means. Â I don't think I'm knowledgeable enough to see or comment on the relative distortion of these lenses with these kinds of tests. I haven't seen any disturbing distortion on my preliminary use of the lens so far, but I think that requires more testing with other kinds of subjects.

steve_l Posted January 8, 2007 Share #12 Â Posted January 8, 2007 Allen- How did you get one of these? We have heard that the new Tri might be undergoing a redesign to allow it to wear a filter more easil on the M8...but we also have heard a few folks who say they have them....

Stevez4 Posted January 9, 2007 Share #13 Â Posted January 9, 2007 How about comparing images before tweaking? Then you could really campare. I suppose that is too simple. Link to post Share on other sites More sharing options...
