macro lens for ist DS
Knockout photo, niblue. Amazing detail. ON the Pentax side, I must agree with George. The Asahi 100mm macro is one of the finest macros ever made, at least based on photos taken with my ST in M42, which I would dearly love to have back today. As for fitting stuff onto a *ist DS, this afternoon ...

macro lens for ist DS
regarding de sigma lens I mentioned in the opening post, I see that the one that I can buy is the version introduced in 1998 which is the EX version of the Sigma lens. Now there is a new version called the DG version which according to the marketing blurb on the website optimized for use on digit...

macro lens for ist DS
since I will be getting my Pentax-A 50mm f1.7 shortly I will be on the lookout for a nice 100 or 105mm macro lens. Manual focus will not be a problem, most of the time you got enough time to focus manually when doing macro.

macro lens for ist DS
Hi, I've been off work today with the flu, so thought I'd practice a bit more with some macro work. I have a little gallery here.. http://www.liamsworld.org.uk/galleries/macro2/ (only 14 images) 30s @ f22 ISO 200 (I was going to post up the one of a match, until my golfing scribbl...

macro lens for ist DS
After seeing Liam's photos I decided to try my Vivitar 55mm macro plus the extension tubes to see what sort of magnification I could get: All taken handheld @ ISO 200 with a single studio flash head for lighting. With the macro lens at 1:1 plus the tubes the subject was just abo...

Newbie's Carl Zeiss - Opinions Please?
Hiya, I was responsible for most of the info on the "fascinating" Zeiss thread a few months back (thanks George)...I use Contax & Zeiss and have researched the recent history for a while now, after becoming frustrated with the dearth of info and so much incorrect 2nd hand info. I...

Watching Ebay with baited breath
I hadn't noticed that A* 200mm f/2.8 before you mentioned it... that's incredibly tempting but could I afford it right now? Hmmmm, probably not as I need an FA 24-90mm. I sold a beautiful A50 1.2 a year back and it reached the princely sum of £160 odd (no box though), the times they are a changin...

Lens "Cleanup"
I guess at the end of the day, we all have very slightly different requirements of our lenses from one another. I for one will keep buying. trying, then selling the ones I don't want to keep . . . as long as my interior minister doesn't find out . . . that is. That's what I'm doing as well. I'm j...

Lens "Cleanup"
Yipeee! My SMC Pentax-A 50mm F/1.4 has arrived! The lens is in perfect condition optically and externally, but the moving barrel (the part that holds the front element) wobbles a bit... at first I found this scary, but the wobble is ver, very small, and from the tests I've made it does not seem t...

Lens "Cleanup"
Be interesting to see how the Porst performs. It's easy to make a good 50mm lens, it seems, and even those from minor makers tend to perform very well. Your Porst cheapo may turn out to be a real bargain. It was cheap for a F1.2 (£25) so I thought it'd be worth a look - I do seem to have ended up ...

Lens "Cleanup"
Primes, however, are another matter, and I submit that for outright optical quality, regardless of price, Pentax is the leading Japanese prime lens maker, and always has been. It's best lenses are unsurpassed even by Leitz and Contax. Until fairly recently in addition to my Pentax kit I also owned ...

As for the rest, the Vivitar Macro teleconverter looks good, and it's like a cross between a teleconverter and a helicoid macro tube! You twist to adjust extension until 1:1 with a 50mm lens. I'll post results here (or perhaps on the recent macro thread) when I have the time. I've got something simi...

My Vivitar teleconverter allows infinity focus. I'll post a few examples later in the evening of my 80-320 with it, as well as a 50mm 1.4 in macro mode.

Pentax-A 70-210mm f4 v Vivitar Series 1 (ver 2) 70-210 f3.5
Mac, If your are perhaps considering the Vivitar lens, which is a little faster but manual aperture only, http://www.robertstech.com/vivitar.htm should prove useful. It was, and still is, a highly regarded lens if you can find the right version. The clue to which one is in the first 2 digits of t...

ASAHI PENTAX SMC 50mm F1:1.2
Thanks George, I couldn't believe it, and to think that I very nearly went for the 280 quid one. I'm sooooo glad I didn't. I do think however that £280 was just a bit OTT, even for this super lens. I have the 3 manual focus 50's now, 1.2, 1.4, and 1.7 in a mixture of A, M, and now it appears, K v...

ASAHI PENTAX SMC 50mm F1:1.2
Sorry, I couldn't resist it at that price. If I decide not to keep it, I'll offer it back here before putting it back on eBay (if that's OK with the moderators). I'm not sure if the forum policy prohibits touting items for sale.

ASAHI PENTAX SMC 50mm F1:1.2
Thank you. I do have to reduce my number of lenses. Having just acquired an ist DS, I will keep a few of the better ones, especially wide angles, and let go anything else that does not get used. I was happy with an M50/1.7 and M135/3.5 for a very long time - they were my first lenses with an MX. eb...

ASAHI PENTAX SMC 50mm F1:1.2
Thanks SMC, but I'll probably keep the 35-70, it'll ideally compliment my SMC-A 70-210 f4 lens when it arives. I'm planning to retire to the sun very soon and whilst I'm still earning a crust I'm buying up the range of lenses that I always wanted, but couldn't afford previously, nor did I have th...
