TOU / FIVE STAR 28mm F2.8

[todd_phillips3]

<p>Picked this up from a guy off Craigslist for $10 yesterday... It seems to have decent quality and from what I've found it's from a company named Toyo.. Perhaps a nonexistent company?<br>

<br /> Anyhow, I discovered that it is manual focus and that it doesn't report back to the camera correctly, or does it?</p>

<p>The camera reports it as a 35mm lens.. Also it's just an aperture ring..</p>

<p>Another question: What is the "Auto" in reference to on the front of the lens?</p>

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

[todd_phillips3]

<p>and here was the first snap I took with it (K100D, 800ISO, F2.8, 1/40s), only one shot before batteries ran out.. My daughter checking herself out in the bathroom mirror before bedtime.. :-)</p><div></div>

<p>This lens isn't listed under the <a href="http://en.wikipedia.org/wiki/Pentax_k_mount#Tou.2FFive_Star">article I just read</a> on wikipedia, but the company is...</p>

[todd_phillips3]

<p>Ok scrap the second question.. I realized just now when I turned the camera on that I must specify which focal length the lens is.. I am with stupid :-)<br>

I still want to know what the "Auto" refers to..<br>

Thanks for the list Jeremiah...</p>

[michael_elenko]

<p>Todd, the "Auto" refers to the auto-diaphragm capability of the lens. You set it at a single aperture and, after focusing wide open, it will stop down to that setting when the shutter triggers the lever.</p>

<p>This is opposed to older preset lenses where the aperture was at the front of the lens. The user would have two rings to manipulate: one for setting the desired aperture for the shot, the second was for opening up the aperture to assist focus.</p>

<p>I have and absolutely enjoy a preset macro lens. Because the aperture control is in the front of the lens, you can dial in and see the desired bokeh without any depth-of-field preview mechanism on the camera body. It's very cinematic in a way and useful.</p>

<p>ME</p>

[todd_phillips3]

<p>Ok thanks Michael! I still don't seem to be doing something right, because whether I set maximum or minimum aperture, I get the same resulting image. I don't know which direction is "wide open" for focus, so I went all the way to infinity and all the way to macro each time I changed the aperture, but I would expect the same resulting shot to be dark at F22 but it was the same exposure as F2.8.</p>

[michael_elenko]

<p>Todd, have you used Pentax "M" or "K" (non-A) lenses on your camera before? I'm just wanting to know your knowledge and experience baseline. . .</p>

<p>ME</p>

[todd_phillips3]

<p>Nope, no knowledge here... :-)</p>

[michael_elenko]

<p>Todd, OK, you'll be an expert within minutes.<br>

1) In the menus, use the custom function "Using aperture ring" and set it to "2 Permitted".</p>

<p>2) Set the dial mode to "M": Set the lens to the desired aperture, compose the shot, press the green button (this will set the assumed correct exposure), shoot.</p>

<p>3) Also in the menus you can set focus confirmation (the red flickering light) to work with manually focused lenses. Very handy.</p>

<p>4) The exposure accuracy may be pretty inexact. I would experiment with exposure bracketing and go through all the trial-and-error shots until you get a feel on how to game the exposure system. You then can set compensation for an automatic adjustment. I just adjust bracketing and shoot away.</p>

<p>5) Your daughter is lovely. Nice color on the shot too. Toyo examples I've seen were pretty decent. For the $10 you've already got an education's worth. But we're all free here :)</p>

<p>ME</p>

[todd_phillips3]

<p>Aha! Press the green button! (mine is black).. That did the trick! :-)<br>

I had #1 correct, and #3, which is why I got the focus close... :-)<br>

Thank you so much kind sir!</p>

[andrewg_ny]

<p>One note on ME's #3: The 'official' in-focus confirmation is the green hexagon symbol in the viewfinder, though the active AF point will also blink when in-focus. I believe the green in-focus symbol remains illuminated after the red AF point light disappears.</p>

[todd_phillips3]

<p>I just tested that per your note Andrew and what it seems like to me is that the red and green come on together upon focus and then the red gets out of the way. Then if you go off focus the green then goes away...</p>

<p>We're missing more photos, so here goes my hijack. K10D + Toyo 28mm f/2.8:</p>

[miserere_mei]

<p>This lens is the reason I fell in love with 28mm on APS-C. If Pentax ever release a full-frame DSLR and I buy it, I'm going to have to buy the 43 Ltd with it.</p>

<p>These Toyos were manufactured in Japan, which is more than can be said for today's Pentax Limiteds. It's a <em>very</em> nice lens, Todd, if you don't mind the stop-down metering.<br>

[donnie_strickland]

<p>I have this same lens in Fujica X-mount. I think it's a very fine lens.</p>

<p>Even the box looks the same, except of course it says, "For Fujica X mount".</p>

[todd_phillips3]

<p>Mis first off, thanks for making me feel like I got some bang for my $10 :-D<br>

I have had the LBA itch for a LONG time (probably a year now, wanting a prime wider than my FA50mm) and never have a dime (or more than $10 at least) to spend on gear so this was my first chance to scratch...<br>

Secondly those are some sweet photos. I remember the first one from when you first released it to public viewing (whenever that was.. last year mustabeen) and am now wow'd all over again...<br>

Thirdly thanks for that PF link... I have to go learn me some stuff.. :-)</p>

<p> </p>

[miserere_mei]

<p>You're welcome Todd. Anything to help out your LBA :-) This was also my first wide(ish) prime, and even though I now have other 28mm primes, I still keep it. At some point I got another one in a bundle auction, and when I tried to sell it on eBay for $15 shipped, nobody bought it! There are *many* fine, old lenses out there that go unnoticed simply because they're off-brand. Cosina has some very nice old primes that you might want to check out if you ever run into one. You might be interested in the Cosinon-T 135mm f/2.8 and 200mm f/4. I got mine for around $20-30 each (shipped). Even though I already owned the FA 50, it was this little Toyo that spawned my love for primes, and it has a special place in my heart because of that :-)</p>

<p>If you want to see some other pics with my Toyo 28mm lens, a lot of <a href="http://picasaweb.google.com/Miserere/LosAngeles?authkey=Gv1sRgCJ3o3azahryUPQ">these I took in L.A.</a> were with it on the K10D. You can click on the "more info" to see the focal length to make sure. Those at 85mm were with the Jupiter 9.</p>

<p>Looking forward to some nice 28mm pics from you, Todd. And don't forget to put the close-focus abilities of this lens to good use--don't be afraid to get up close and personal.</p>

[todd_phillips3]

<p>Well went out with this little $10 gem for the first time this afternoon along with a couple of my kids and had some fun... Here are a few of my snaps..<br>

[jgredline]

<p>I missed this thread the first time around. Mis, that first shot of yours looks familiar to me. Looks like the dysney concert hall...???</p>

<p>Todd, That last one is my favorite I have seen from you.....Spectacular!!!!</p>

[miserere_mei]

<p>Yes Javier, that's the Walt Disney concert hall. I loved that building and would very much like to go back for another session with it.</p>

<p>Todd, good job on that B&W. Let's see more!</p>

[todd_phillips3]

<p>Oh that's interesting.. they seem to have disappeared! hmmm</p>
