    Considering to switch to Four-Thirds ...

    in Olympus

    Posted

    <p>I have a Canon 5D II full frame and a Canon 7D (APS) and i wanted to get a 4/3 for those times I didn't want to lug around the weight. So I got a Panasonic GF-1 and three lenses (pancake, 2 zooms)<br>

    Now I tend to take the 4/3 with me way too much. Incredible, colorful pictures and light weight. Plus the gear is far less cost than the bigger brothers.<br>

    If I'm shooting a landscape or portrait to hang on the wall, though, I'll still grab the SLR</p>

     

    Helpless: eBay Leica fraud (had been cheated $3300)

    <em><strong>Yep---I sell frequently on ebay (I have a Canon Rebel there now).....and this is relatively recent policy. Payments for certain "high risk" items for sale are held until buyer satisfaction is obtained or a number of days has past.</strong></em><br>

    Prime Deficiencies for Canon full frame and 1.6X

    in Canon EOS Mount

    <p><em>Yes, I have asuggestion, buy the 50/1.2, you are already happy with it and for General Portraits it will suffice on both cameras.</em></p>

    </blockquote>

    <p>I reread my post and realize I forgot to add the price point of the Canon prime L's are not justified for my occasional needs<em><strong>. </strong>Otherwise, I agree and I would certainly now own both the 50mm f/1.2L and the 35 mm f/1.4L </em><br>

    But, alas, I'm looking in the $300-$600 range and I wouldn't mind a lens that is soft in the corners (Canon 1.4) but I would get cranky if I had a focus issue (Sigma), CA's or poor contrast/color. <br>

    After reading the above great feedback, I feel much better about the non-L's</p>

    Prime Deficiencies for Canon full frame and 1.6X

    in Canon EOS Mount

    Posted

    <p>I occasionally need a large aperture prime, usually for portraits and can't find a good candidate other than the Canon L's -- the 50mm f/1.2L (for my 5D II) and the 35 mm f/1.4L (for my 7D)<br>

    The Sigma 50mm f/1.4 looks perfect except for the focusing issues. I was searching the web but can't find if these focusing issues have been resoved by Sigma or are still out there.<br>

    The reviews of Canon's 50mm 1.4, 1.8 and 35mm f2 are not good. Likewise the third party lenes excepting the above Sigma.<br>

    Anybody have a suggestion here? </p>

    Going to Europe...Need a Tripod

    in Accessories

    Posted

    <p>I'm going through the same search myself (I have a Canon 5D MII, w/70-200f/4) . I've eliminated the Gitzo on price. I've narrowed it down to the Velbon Ultra Luxi L, Velbon 640 (or maybe the 530 - longer folded dimension, but good price at Best Buy), the Manfrotto magfiber. Maybe the Slik Pro EZ and maybe the Indura (not sure how those leg locks work)<br>

    I often take a spotting scope so the tripod does double duty and I need a panning head as well, which complicates the search a little.<br>

    I also don't want the individual leg twists that take forever and a day to set up. <br>

    Still looking !!!</p>

    5d mark II strange black dots?

    in Canon EOS Mount

    <p>Rishi<br>

    I think what your saying is the extended ISOs are similar to PUSH and PULL processing of film. <br>

    If I have time today, I''ll run some "Ansel Adams" curves of the 5D II sensor. I'm thininking of shooting a plain white paper at a ten stop EV range (Ansel's Zones I-X) at 4 different ISOs (50, 100, 800, 25,600) and maybe 2 or 3 different light intensities (because of the wide ISO ranges) - with two of the ISOs in Canon's "extended range" (50 and 25,600). With that ISO range, I'm not sure I can do this. Probably need a flash set up.<br>

    Photoshop's histogram data gives the mean intensity value as well as the data for each color channel RGB and CMYK. I'll take both RAW and JPGs but I think I want RAW here.<br>

    Then a plot of the data (X-axis: EV and Y-axis:Photoshop mean intensity) should reveal if anything is different in the extended ISOs (I'm sure it is - otherwise it wouldn't be an option on the camera).<br>

    The heel and toe of the plots will reveal if there is any loss of highlights or shadows at the various ISOs</p>

    <p>The above post was the Canon announcement from the Australian web site. It is now duplicated on the Canon USA web site. Here's the complete text:</p>

    <blockquote>

    <p>We have learned that some users of the Canon EOS 5D Mark II digital SLR camera have identified two types of image quality phenomena that appear under certain shooting conditions.</p>

    <ol>

    <li>“Black dot” phenomenon (the right side of point light sources becomes black) </li>

    <li>Vertical banding noise </li>

    </ol>

    <p> We are currently investigating and analysing the causes, and examining measures to reduce or eliminate these phenomena by providing correction firmware. An announcement will be made on the Canon Web site when such measures have been determined.<br>

    <strong>Details of the phenomena and shooting conditions under which they are likely to occur are as follows.</strong></p>

    <ol>

    <li>“Black dot” phenomenon (the right side of point light sources becomes black)<br />When shooting night scenes, the right side of point light sources (such as lights from building windows) may become black. The phenomenon may become visible if the images are enlarged to 100% or above on a monitor or, if large prints of the images are made. </li>

    <li>Vertical banding noise<br />If the recording format is set to sRAW1, vertical banding noise may become visible depending on the camera settings, subject, and background. </li>

    </ol>

    <ul>

    <li>Vertical banding noise is not noticeable if the recording format is set to <strong>sRAW2</strong>. </li>

    <li>Vertical banding noise does not occur if the recording format is set to <strong>RAW</strong> or <strong>JPEG</strong>. </li>

    <li>Noise can be reduced if C.Fn II-3: Highlight tone priority is set to <strong>0: Disable</strong>. </li>

    </ul>

    <p> Interesting - The Pop Photo review is now on the web</p>

    <blockquote>

    <p>"But this low-light performance isn't glitch-free. As have commenters on the web, we noticed tiny black blotches next to areas of blown-out highlights, such as the streetlights in our image of the skater. We found it hard to predict what images these spots would turn up in -- sometimes we'd find them, sometimes we wouldn't. Canon is aware of the problem, and our bet is that the issue soon will be resolved with a firmware upgrade. In any case, the blotches are easily removed in postproduction." - Pop Photo in tehir review<br>

    Some advice needed - Flash w/slave

    in Wedding & Event

    Posted

    I've got a wedding at the end of the summer (plenty of time)...but

    I'm doing this as a favor (normally I do landscapes and stills)

     

    So -- I'm going to practice !!!

     

    I have a med format (Pentax 645), 35 mm, and 4x5 view (think I'll

    leave that home) plus a Quantum T4D with a TTL for my cameras.

     

    For indoor formal group shots - I'm wondering if I can get by with

    the flash off to the side with the diffusion cover for the

    reflector. Or another option is I can rent a Quantum slave flash

    and do fill from the camera. Are umbrellas a good idea?

     

    For outdoor - I'll use on-camera fill?

     

    Like I said - I'm going to practice....but I'd appreciate some

    experienced advice as I don't normally do weddings.
