Advertisement Posted January 26, 2018 Posted January 26, 2018 Hi rnl, Take a look here Getting used to new lens: Summicron 90mm APO. I'm sure you'll find what you were looking for!
a.noctilux Posted January 26, 2018 Share #2 Posted January 26, 2018 Nice parrot. I assume that you focused on the eye, then reframe. (if with RF focussing) I have nothing more to recomment. I see that the Apo 90mm has flat field, here the focus plane remain even in the border of the frame. Link to post Share on other sites More sharing options...

I'm coming from the Canon system..a 1dxmkii with fully automatic focusing and stability assisted lenses. It's been a while since I manually focused a lens..probably around 40 plus years. I got this beast in 1971. Bought tri-x in bulk, wound it into cans and developed in daylight tanks. Had a cheap Durst enlarger and a few trays set up in the basement. Bought the m10 last month as well as a summilux 35, summicron 28, 50 and the 90 and am enjoying slowing down to take exposures. Welcome, dear visitor!

As a fellow 1DX owner, Richard, I, too, appreciate slowing down and manual focus. I’m wondering how long before we can convince you to get a film M to share that 90 with the M10. In the meantime, give the Mamiya a birthday present with a CLA, and come and join us at the “I like film...” thread on LUF https://www.l-camera-forum.com/topic/205842-i-like-filmopen-thread/page-2325?do=findComment&comment=3447686 Link to post Share on other sites More sharing options...
Keith_W Posted January 26, 2018 Share #6 Posted January 26, 2018 The streakiness on the feathers looks more like motion blur to me rather than being out of focus. What was your shutter speed? Link to post Share on other sites More sharing options...

What was your shutter speed? he "shivers" when he's happy....1/60...I am going to set the camera for no less than 1/focal length or 1/90 Edited January 26, 2018 by richardlipow Link to post Share on other sites More sharing options...
Gregm61 Posted January 26, 2018 Share #8 Posted January 26, 2018 (edited) 90mm and f2 is pushing the limits of the rangefinder if camera+lens are not perfectly aligned with one another. I have had enough issues with the 75mm f2 APO. I also have a pre-APO Canadian-made 90mm f2 Summicron that I had Leica 6 bit code that focuses accurately enough with my M262 but it's certainly easy to *just* miss at 90mm and f2 and have it ruin an image. When in auto ISO, I have my camera set to 4x focal length. I have no illusions regarding shooting with 75-90mm lenses, no image stabilization and hand-held that 1/60 second is fast enough to keep anything tack sharp, which means the ISO's going to be topping out quite a bit in lower light or indoors, but I'd rather maximize the shutter speed to minimize possible camera shake.

lct Posted January 26, 2018 Share #9 Posted January 26, 2018 I see nothing to criticize in your pic. It shows no significant camera shake otherwise the eye would not be sharp. Now DoF is thin on 90/2 lenses at f/2 and Leica rangefinders are at the limit of their accuracy there so the best advise i can give is to focus bracket or use an EVF when you can.

Michael Geschlecht Posted January 26, 2018 Share #10 Posted January 26, 2018 Practice, practice, practice. The more you use it the more proficient you will get. No other suggestion! Hello Richard, Welcome to the Forum. Nice photo. Along with Paul's (As usual.) good advice I would like to add: Altho the photo is reasonably sharp I do detect a degree of camera shake. Camera shake is always multiplied by an increase in focal length since an increase in focal length increases magnification & an increase in magnification means an increase in all aspects of the image. Which includes an increase in camera shake. Meaning: A degree of camera shake that might have been acceptable with a shorter focal length lens becomes more obvious as the focal length increases. 1 way of lessening camera shake is to carry a small, solid, table tripod with soft, non marking slippers, along with a large ball head & a cable release. A photo taken with a tripod is often noticeably sharper than the same photo taken without 1. Against my chest this combination gives me + 2 stops of stability. Against a wall (Soft, non marking slippers.) or in the side of, or above, a doorway, against a rock or against a tree, on a car with the engine turned off, or even on a table: It gives you an unlimited number of additional stops of stability And sometimes a photo at 1/8 of a second @ F8 gives a different photo than the same scene done @ F2 & 1/125. Or, the F2 @ 1/125 is somewhat sharper than it would be hand held. Sometime just a cable release alone, without the tripod & ball head, adds to stability, or the ability to take a photo. The more you use this combination the more ways you find to use it. As a factor of this I have pretty much left a full sized tripod at home for a number of years. Best Regards, Michael Link to post Share on other sites More sharing options...

pgk Posted January 26, 2018 Share #12 Posted January 26, 2018 The old 'rule' of using a shutter speed which is roughly the reciprocal of the focal length applied well to film but with today's high MPixel cameras I find that I have to use the next, higher shutter speed. So for a 90mm I'd be using 1/180s or preferably even 1/250s to ensure minimal or no motion blur. 2 Link to post Share on other sites More sharing options...
Csacwp Posted January 26, 2018 Share #13 Posted January 26, 2018 I wouldn’t shoot it at less than 1/180th of a second handheld... The 90 apo is good wide open but truly spectacular at f/4... Link to post Share on other sites More sharing options...
lct Posted January 26, 2018 Share #14 Posted January 26, 2018 I am fortunate enough to own Summicron 90/2 v2, v3 and apo. I like them all but the sharpest at f/2, in the centre of the frame at least, is obviously (to me) the apo. Link to post Share on other sites More sharing options...
rnl Posted January 26, 2018 Author Share #15 Posted January 26, 2018 Thanks for your comments...it appears from what you have all said that this camera with a 90mm is similar to my 50mp Canon 5dsr. A tripod and or high Sutter speed is a must for that camera. The attached was shot with a tripod and bounced flash. Welcome, dear visitor!

Paul J Posted January 27, 2018 Share #16 Posted January 27, 2018 (edited) Nice African Grey. Shoot at 1/250th or higher where possible. Tripod is not necessary. Practice. Practice. Practice some more. Try the 1.4 Magnifier - I highly recommend it. Try the grip - I highly recommend that too on the bigger longer lenses that need more stability. In the meantime you can increase your hit rate by focusing best you can and then focus bracket by moving your body slightly back and forth while taking photos.

Paul J Posted January 27, 2018 Share #18 Posted January 27, 2018 (edited) thanks..he's 20 years old and has quite an attitude I can see! I used to keep birds when I was young and I had many parrots and cockatoos amongst others. The larger parrots in particular are very funny and each one is unique in character. I had one Corella which was the craziest. He would do all sort of things like hold on to the perch and spin around in circles doing somersaults (think gymnasts spinning on high bars), doing it for minutes at a time. Ridiculously intelligent too and would look straight through you. That first shot you've posted is my favourite. It's really good! I like the ambient blur from it.
