    Nikon 180mm 2.8 manual mode

    in Nikon

    Posted

    <p>Dear, I am dealing a used Af 180 ED 2.8 and I got a question from a guy interested:<br>

    Is this lens going to manual mode - aperture and focus with those Nikon bodies: <a>D40,D3000 e D5000?</a><br>

    I am not sure! This lens has a aperture ring and focus ring but in my D2H I have to set manual focus into the body.</p>

    <p>Thanks for help, Rubens</p>

    <p>Hi Charles,<br>

    I have a SU-800 and Sb's and seems to me that most of us start as you are. I would assume that in near future you are enjoing monolights that can be cheaper than SBs with much more power.Why not mix those?<br>

    I would bet that you are not so concerned with CLS as far as you might want control your light in manual mode. So take a look at radioppoper that promises high sync, groups ( as SU-800 does ) and commander for monolights - like AB and speedlights<br>

    Good luck, Rubens</p>

    Nikon wireless speedlight commander

    <p>Hi Walter, here is one of those that has observed 04 drawbacks over SU-800, ( I got one and 02 SBs)<br>

    a) Infrared is not really a good technology if you compare to RF. I got problems loosing signal even in studio when umbrellas obstruct those pulses from SBs and SU-800. In bright sun light you can have the same problem. At this moments you get bored loosing time to reconfigure angles!<br>

    b) the distance between commander and flashes are very restricted, again compared to any device RF.<br>

    c) SU-800 has a fixed axis and you are not allowed to rotate and get better connection between commander and speedlights., again searching better signal <br>

    d) This commander SU-800 will not fire monolights and other setups than Nikon.<br>

    I am now watching some posts over radiopopper that could assemble strobes and speedlights ( multi-brand, and old oneswithout PC connector) <br>

    Marten, be careful now and look for strobist and other reviews to make your final decision. Good Luck, Rubens</p>

    <p>Hy joseph, <br>

    Thank you. Sorry for any misunderstanding. You definitely got my points and “reliable” is related out of Paul C. Buff's brand (products and reviews).<br>

    a) If you have time and thinking in Radiopopper solution, please explain me why some posts and guys are trying to plug Nikon AS-E900 flash adapter to Nikon speedlights instead of PX receiver?<br>

    b) How come is possible assemble SU-800 into radiopopper setup? I could not follow you!<br>

    Tks, Rubens</p>

    <p>Dear,<br />I am going to purchase a set of wirelles triggers in near future. My first option would be wait for PW and new models for Nikon but the delay is on and I am not sure if my budget is up to afford it.<br />I do have Nikon gear + SU-800, Nikon Speedlights, Monolights and asssemble those in some moments - is my real world, thinking in locations.<br />Looking for other options, you can find SyberSync with his reliability and the new RadioPopper that promises link strobes and speedlights ( that would be really nice ) in <strong><em>JrX Transmitter and JrX Receiver Studio </em></strong>16 channels, 4 groups of control. Here with a great hand from Strobist.<br /><a href="http://radiopopper.com/blog/2009/08/14/the-big-jrx-announcement/">http://radiopopper.com/blog/2009/08/14/the-big-jrx-announcement/</a><br />Please, I would like to ask for some tips over those products and considering their features including HighSync for AB and Speedlights.<br />Tks, Rubens</p>

    Nikon D2Hs vs. D2X

    in Nikon

    Posted

    <p>Hi Zirab, I agree in part of many posts you red so far. Here is mine: - I got my D2H 03 years ago after reading many respcted reviews as Thom Hogam, DPreview and so. Besides a Nikon Gear with their reliable tech, there was a consensus out that you must be <strong>aware of </strong>getting noise in two moments: - under-exponsing a shot will bring you a severe noise at blue channel and don't expect to solve it in post - production, - High ISO like 1000 and over, you are really in trouble in most situations.<br>

    About resolution, never mind! You can print a tabloid size with no problems and I don't think you are up-scaling more them this.<br>

    Regarding this drawbacks, this is a tremendous body that has real quality and performance. But If you can afford to D2X anytime, don't miss it and you are skipping those issues described and new resolution.<br>

    Regards, Rubens</p>

    <p>Dear,<br>

    Dear,<br>

    I am searching for any real and good solution for connecting my D2H to a computer wireless or wired. Actually, I Bought a Nikon WT-1 ( transceiver ) one year ago and downloaded free version of third part software to help it. But never got good stability. Now I upgraded to vista and “Bug”. For now, it doesn’t matter if I will be wireless or not. The goal is connect the camera in real time with a computer in my studio.<br>

    I’ve been seeing some short videos with a tripod with camera and a laptop connected for studios and locations. I am not sure if the laptop is wired or not. Anyway, how come download files wired to a computer in real time? USB + software ( witch one?).<br>

    <br>

    Thanks, Rubens</p>

    <p>Dear,<br>

    After reading some posts I decided to aply a Chroma key color into a studio background. For a test I asked a Coral Paint dealer do mix a Pantone color code 354 for green and 2735 for Blue. But, it fails!<br>

    Photoshop could really not extract hair with his best tools. <br>

    So, is possible do it with pantone codes otherwise I must look for Rosco?<br>

    Thanks, Rubens </p>

    CA - chromatic aberrations

    in Nikon

    Posted

    <p>Dear,<br>

    Usually and reading lens reviews, CA always comes as a problem in some lenses and have penalty for this issue . Otherwise, those reviewers use to say that post-processing would resolve it! How come?<br>

    I tried in Lightroom that has sliders to this, in Photoshop also and never got any good result applied to any color fringing. <br>

    (Shooting with Nikon 180mm f/2,8 and other Nikon lenses )<br>

    Any Help? <br>

    Tks, Rubens</p>

     

    tokina 80-400 vs tamron 70-200

    in Nikon

    Posted

    <p>Hi Lisa,<br>

    Actually I have the TOKINA AT-X 80-400 and I am now sending it to Adorama as a trade. In fact, this lens can't go beyond 300mm, or you will get softeness. From 80to 300mm is a kind of decent lens, very compact, and superb construction.<br>

    For prime results I decided to a NikonAF 300mm ED f/4 and a 1/4x Converter - just in case.<br>

    Take a look at KEH.com for more possibilities!<br>

    Bye.</p>
