<p>I am using a Canon 5D Mark II with an EF 17-40. I tried image playback with the INFO button to see the detail in EXIF but could only see the shutter speed, ISO, F-stop, histogram, metering mode, time stamp etc. I did not see any focal length related information.</p>

<p>Could you point me to the menu option I should navigate to?</p>

<p>Gurus,</p>

<p>Is there a way to know what the exact focal length a zoom lens is set at (just like the F-stop) when one is shooting out on the field?</p>

<p>The ring on the lens barrel has markings but one can get only approximate readings from this. The exact focal length does get recorded in the picture meta-data and can be queried during post processing.</p>

<p>Thanks a ton.</p>

<p>Thanks a lot everyone for your feedback and advise.</p>

<p>I did check up with RRS and they have confirmed : "Yes to all of the questions".</p>

<p>Peter N has raised a point that I had not thought of before - location of the knobs with respect to the slot.</p>

<p>Pictures on <a href="http://www.adorama.com/images/large/AWMBZ1SPF.jpg">Adorama</a> show it to the left of the slot; <a href="http://www.bhphotovideo.com/images/largeimages/469923.jpg">B&H</a> shows it to the right. DUH !!</p>

<p>I'll be visiting the store before buying the ballhead and legs (Gitzo GT2542L) to verify they meet my needs and I don't run into any usability challenges.</p>

<p>Hello,</p>

<p>I have been reading up on ballheads and quick release systems and am almost decided on buying a Arca-Swiss Monoball Z1 sp (Single Pan) Ballhead with Flip-Lock Quick Release (Mfr # 801104). I prefer the Flip-Lock QR over the Screw QR because it provides visual confirmation on the locked / unlocked status. I’m thinking of using this ballhead with RRS (Really Right Stuff) plates. Questions:</p>

<ol>

<li>The width (distance between “A” & “B” in the attached picture) of the Arca-Swiss QR clamp can be adjusted by turning the nut “C” in order to provide a snug fit for the plate. Correct?</li>

<li>Are the RRS plates compatible with Arca-Swiss clamp included in the ballhead?</li>

<li>It is possible to change the clamp included with Arca-Swiss ballhead by removing the hex headed screw marked “D”. Is this fairly straight forward and doesn’t require specialized tools (or sending it in to a service center)?</li>

<li>Can the RRS clamp B2-PRO II be mounted on the Arca-Swiss ballhead after removing the clamp included with the Arca-Swiss ballhead?</li>

</ol>

<p>Thanks / Divya</p><div></div>
