jrp Posted October 25, 2016 Share #43 Posted October 25, 2016 The JPEG embedded in the DNG is notoriously poor quality. Hope that the JPEG that you are using is the sidecare one. Link to post Share on other sites More sharing options...
turbonetics Posted October 25, 2016 Share #44 Posted October 25, 2016 Good morning. Ok, I tried a kitchen shot, focused on "2" of the tape measure - AF, ISO 50, 90mm, f8, 0.8sec - 20 sec timer using a v sturdy tripod/head Same results using MF and AF at f4 and f8 the subject that u are focusing is bit far away and it is close to the background colour and if u are using AF for this shot, there is chances that the AF system may not get an accurate focus. for MF did u enlarge for precise focus or just based on the focus peaking?

Thanks to all for contributions - all v helpful! for this 100% cropped, it looks like the focus is on the chopping board and considering the amount u crop the chopping board looks decently sharp. I don't see anything wrong with your lens. Link to post Share on other sites More sharing options...
thighslapper Posted October 25, 2016 Share #46 Posted October 25, 2016 this is the best I can do from the jpg of the same image ....... Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! colours are crap and I cannot get the same clarity and sharpness that I could with the DNG I have NEVER used JPG from any Leica camera ....... DNG processed in LR is always miles better. Still doesn't explain the degree of discrepancy though ......

LD_50 Posted October 25, 2016 Share #47 Posted October 25, 2016 Advertisement (gone after registration) I understand the idea of thinking the jpg "should" be of satisfactory quality but if you're trying to determine if the lens has an issue you should remove as many variables as possible when testing. Shoot a static target (tape measure is fine) that is perpendicular to the sensor with enough contrast to determine in the EVF or Live View screen that it is in focus. I would use magnification to make the determination. You could also focus bracket if necessary. Shoot on a sturdy tripod with OIS off. Use 12 sec timer or remote release to eliminate the possibility of camera shake. Shoot with high enough shutter speed to eliminate the same. Shoot DNG and compare various sharpening in post-processing. Shoot with another lens with the same setup. You should have everything you need to determine whether there is a lens issue.

steppenw0lf Posted October 25, 2016 Share #48 Posted October 25, 2016 Nobody has an easy explanation why you get these results, it seems. The camera is also new, so maybe you could do a reset to factory settings (to exclude any strange settings in the jpgs, etc.) If you have made some customizations, you can save them first, and play them back again later (after the camera reset).

JamesBarry Posted October 25, 2016 Author Share #49 Posted October 25, 2016 Thanks to all. The lens is going back and replacement arriving tomorrow. Thank you Thighslapper. LD_5 - yes, tests conducted as you mention - magnification used, focus peaking of little interest, sturdy tripod with non ball head / OIS off, 12 sec timer. I ALWAYS shoot DNG only. However, for the sake of these tests, DNG + Jpeg used and imported to LR together. I wanted to compare the difference between the two files. Correctly processed DNG will, of course, come out better but unfortunately my confidence in this lens is just not there. Can't wait to test the replacement.

Robert E Posted November 11, 2016 Share #50 Posted November 11, 2016 Hi James, I have been doing some random test shots with my 24-90 and I'm not all that happy with the sharpness either. The reason I got it was mostly 1. for the OS (or VR) and 2. the most used focal length for all around carry lens. This lens is really large and heavy, so I expected more from it, to justify carrying the weight around. I'm very careful to make sure the shutter speed is high enough to prevent motion blur anyway, but the sharpness seems to be lacking. Here is a recent .jpg shot son a sunny day, from sitting position, focus is on the gate top rails, no LR adjustment at all, 50mm focal length. These were just the most recent shots taken that left me wondering about where the sharpness is? Let me know what you think. Thanks. Welcome, dear visitor!

Robert E Posted November 11, 2016 Share #51 Posted November 11, 2016 And another shot taken a day earlier, focus is on the sign which is about 50' away, again at 50mm focal length from a sitting postion.

dgktkr Posted November 12, 2016 Share #52 Posted November 12, 2016 Hi Robert, On my computer screen the two images you show look fine to me at the resolution that is shown. Are they cropped from the original captured images? If not, could you do 100% crops containing the sign and rusty hinge from the first and the sign in the second? dgktkr Link to post Share on other sites More sharing options...
thighslapper Posted November 12, 2016 Share #53 Posted November 12, 2016 cannot comment without knowing...... whether this is a general issue or just some images original image resolution whether original is dng or jpg sharpness setting in camera if jpg sharpness applied in processing if dng or jpg OIS on or off shutter speed and aperture whether more sharpening applied or not when reduced to forum size (LR gives several options) 100% crops of your target focus area required comparison with a different manual focussed lens for the same subject with the same settings if you use LR the default sharpening is 25 ...... which is not sharp and that has nothing to do with the lens and is a sensor bayer matrix de-mosaicing issue that affects all digital images Settings of up to 100 on the sharpening slider incur virtually no artefacts and can be used. when it comes to jpg and other RAW formats manufacturers all have their own idea of what default sharpening should be for 'normal' output...... Leica, Nikon, Canon and Fuji all differ..... all of this needs to unpicked before you can blame the lens ..... Link to post Share on other sites More sharing options...
250swb Posted November 12, 2016 Share #54 Posted November 12, 2016 And another shot taken a day earlier, focus is on the sign which is about 50' away, again at 50mm focal length from a sitting postion. The blue sign? In a scene like that focus should have been set much closer, on the bell for example, using to your advantage the principle that you have more DOF behind the focus point than you do in front of it. The gate picture looks like you didn't lock focus on the gate at all. It could be movement blur which will be exaggerated on closer objects, so be sure to have your shutter speed well up, or take a monopod with you.

Robert E Posted November 14, 2016 Share #57 Posted November 14, 2016 Sorry for the late reply guys, just been busy with "life' lately. As far as the photos go, I did focus on the gate, in the one photo; and on the history sign on the silver pole (not the bell area) in the other photo. Area of focus is small center weighted, and camera handheld with OS on. Neither photo is cropped, I tried doing 100% crop but could not get it to post. I will try to post the 100% crop photos again below. Aquarius2014, I did look at that link, and wanted to let you know the link ending in 380 is exactly what I'm experiencing. When cropped 100%, it's not that sharp. On my photos, I DO NOT use LR sharpening, maybe I should learn how to do that. Thanks for all your in put.

Hi Robert, yes, the 100% crops of the images that the 380 link leads to look soft because they are DNGs converted to JPEGs with no sharpening applied whatsoever, neither in LR and, by definition, nor in-camera. 100% crops of DNGs always look soft until sharpening is applied in post (see link ending in 301). I understood that yours are OOC JPEGs and the focus area should look crisp and clear out of camera. Link to post Share on other sites More sharing options...
