<p>Hello there,<br> I've been struggling with this issue for two days now, and I'm kind of giving up on it.</p> <p>Got D610 + Tamron 24-70 + Nikkor 80-200 2.8 (two ring).</p> <p>A few days ago, i shot some studio portraits with the 24-70, and got some front focus on it, so i decided to do the af fine tune, as i've done in my old DX days with other bodies.<br> Printed the <a href="http://regex.info/blog/">Jeffrey Friedl's Blog</a> charts, and started to do the test.<br> I was very careful with the setup, as i've always done.<br />Got wrong results every time, so i guess I'm doing something wrong.<br> I took a shot at "0", then at "+20" and then at "-20". The results were almost identical. <br />I double checked i had the AF tune in "ON". Wasn't using LiveView since i read it won't work with it.<br> This was with the 24-70, since it was the one with the front focus problem. And i just repeated the test with the 80-200 just to check, and still the same.<br> Would it be possible there are lens (or bodies) that won't respond to this test?<br> What am i missing?</p> <p>Best,<br />Luis.</p>

<p>I guess i'll use it in "A" for candid 1.4 "creamy" portraits, then. Haha. Thanks BeBu.</p>

With what you said I think there is something wrong with the shutter speed dial and even if you don't care about metering your camera won't work in manual as you can't set the shutter speed you want.</p> </blockquote> <p>Yes, it shows the selected speed. And yes, the curtain moves at the "right" selected speed. This is driving me crazy, haha.</p>

<blockquote> <p ><a href="/photodb/user?user_id=5994753">BeBu Lamar</a> , Jun 25, 2016; 03:26 p.m.</p> <p>Put it back in A and set the ASA to 100. Aim at a relatively bright subject like daylight outdoor. Change the aperture and see if the shutter speed changes accordingly. Use your DSLR also set at A and center weighted and compare to see if they are closely the same. If it pass this test the take it out of A and point the camera at a relative dark subject and also close the lens down to a small f/stop. Setting the aperture to f/1.4 tends to get the meter to indicate a "+". See if it would change to "+ -" or "-". If it does then try to change the shutter speed to see if it has any effect. If changing the shutter speed doesn't change the meter reading then the shutter speed dial "gray code" encoder is faulty. When you set the shutter speed dial it generate a binary number that feed into a circuit to generate an analog voltage accordingly. This voltage is then fed into the metering circuit along with the combined sensor output, aperture setting and ASA setting also fed into the meter. The meter then compares the 2 value and display accordingly.</p> </blockquote> <p>While doing this, got the "-" back in some points. But in some really weird readings.<br> My DSLR was reading a correct exposure at one settings, and the F3 at another "close" settings.<br> At the same light source, with the DSLR in center metering:<br> f11 1/60 200 f3<br />f/11 1/15 200 d610<br> The "-" came back only when i pressed really hard the button on the speed dial. If i depress it, is gone and always shows "+".</p> <p> </p>

<blockquote> <p ><a href="/photodb/user?user_id=2002499">Brian S.</a> , Jun 25, 2016; 02:27 p.m.<br />Oh, forgot to ask... The shutter speed correctly changes when aperture is adjusted and camera pointed at a constant source??</p> </blockquote> <p >If you mean in "A" mode, yes, it changes.</p>

<blockquote> <p ><a href="/photodb/user?user_id=2002499">Brian S.</a> , Jun 25, 2016; 02:25 p.m.<br />If it works in A I'd assume also that the metering is working. But M should show both + and - depending. What ASA are you using and is the counter >1? Is that the +80 "problem" you mention? It's not a problem; it's a feature. Check to make sure the tab on the body that connects to the Aperture ring on the lens is in the correct down position.</p> </blockquote> <p>I tried all the ASA's with all the f/stop+shutter combinations possible. Still all "overexposed".<br />Yeah, the +80 thing i was referring to, i knew is a feature, that usually people think as a problem.<br> The tab is in the correct down position.</p>

<p>Hi guys.<br> I recently got a F3 in a very good condition.<br /><br /><br> Coming from a DSLR, i knew i needed to read the whole manual, and search for "tips/tricks" on the web.<br> But there's something i cannot figure out, and maybe it's just a stupid question or the camera has some faulty meter.<br> When i use it in "A" it meters perfectly, i point it to a light source and it shows a faster speed, intermediately i point it to the dark, and it shows a lower speed.<br> That makes me think the meter system is ok, right?<br> The problem comes when i use it in Manual. It's supposed to show in the LCD the Shutter Speed, the "M" and the "+" / "-" sign depending of the light, right? Well, it ALWAYS shows the "+" sign. Even with f/1.4 straight to the sun or to the dark. It just won't change.<br> Am i doing anything wrong? (is what i think is the problem)<br> I'm aware of the +80 problem. It's not that.<br> If you have any advice i'll appreciate it.<br> Regards,<br> Luis.</p>

<p>You are right.<br> It's going to service, then.<br> Thanks :)</p>

<p>It does work on manual and AF. It just worries me, that being loose can damage some camera mechanism.</p>

<p>Hello to all.<br /> I just got as a gift from my uncle, a 50mm 1.4AF (The older version).<br /> One thing, is the blades stop at f/8. The dial even goes all the way to f/16 just it won't close more than f/8. Is this too bad to fix? I can live with it, i wanna use it in 1.4 anyways.<br /> It's in pretty good condition, and when i was handling it, it accidentally fell from my lap. Nothing broke (i guess), just the tiny screw that rotates (the focus system) was out of the lens. I just put it back in, and the lens is fine, the screw just sometimes falls out the lens.<br /><br /> I can live with this, but, is it in some way going to damage my camera body? What can i do before taking it to a technician?<br /> Just noticed, on Live View, it has problems focusing. It just stops focusing and I can hear the motor trying to do the focus, but it just won't do it.</p><div></div>
