Extension Tubes
Hi, I have just purchased a set of Pentax 6x7 extension tubes on ebay. I have never used tubes before so I'm just trying to figure out a couple of things. Hope someone can help with the following questions... 1. What scenarios lend themselves to using the tubes? Am I right in thinking t...

Extension Tubes
Hi Rick, 1. You are absolutely correct; they'll effectively turn any lens into a macro lens (the shorter the focal length of the lens, the higher the magnification you can achieve). They won't increase reach like a teleconverter. 2. No real limitations but you'll see more pronounced effects (h...

Extension Tubes
Hi, ...Hope someone can help with the following questions... ...Rick 1) In general, extension tubes are just that: they extend the distance from lens to image, thereby permitting a larger reproduction ratio (i.e. magnification) 2) Again in general, the shorter the focal length of the lens...

Thanks for the responses. I'll try and get out with the camera and tubes in the next day or two to try them out. A couple of thoughts and conclusions on the replies so far... 1) Seems best to use these for close-up/macro type work rather than trying to use them for the 'extra reach' (eg wildlife ...

Extension Tubes
Hi Rick, What an interesting topic this is but it seems to me a lot of people are confused about the use of extension tubes on P67 or P67ii. The simple fact is it does not matter whatever the tubes are manual or automatic as there is NO LINK between the tubes and the METERING SYSTEM of either 6...

Asahi Pentax 6x7: some questions.
Hi all, I am having an extended look at an Asahi Pentax 6x7 (it looks to me to be the original 1969 model without MLU) in very reasonable but well used (not abused) working condition: it shows brassing on all corners and along some edges. The mirror is exceptionally clean and there is no obvious ...

Squeeze the front and back of the retaining clip together and push downwards.

Considering medium format...
I've noticed a fair number of cheap Bronica ETS/ETSi outfits on ebay of late, but I'd rather stick with Pentax, so... I'd like something which takes 120 film (or can do), but I know little about medium format beyond a brief dabble with a Lubitel 166U years ago. I'm aware that Pentax have made the...

Considering medium format...
I sold a Pentax 645 outfit a few months back (body, film holder and 80mm lens) on eBay for £175 so it is possible. The one I sold was a little tatty but perfectly useable. I've had fun with various folders and it's certainly the cheapest way to get into medium format shooting, just don't forget t...

A question for the Gurus
... think of taking a photo of a small ornament. A 50mm macro is used to take the image. Now we decide to use a 100mm macro to take the same image, but 100mm lenses have less DOF? Yes, at the same distance... John, Interesting that you should use this particular example, as I have noticed (when t...

AP Test 645D
AP have published their test of the 645D. It's a broadly impressive review, with the remarkable resolution and quality being mentioned with some enthusuasm. The autofocus speed is also very highly rated. It was quite clear that it produces very superior results to the high end DSLRs from Canon and N...

AP Test 645D
Lottery? I'm afraid its my turn this week. I told the guy in the shop that I'd be looking for my money back tomorrow if I didn't win and he said I would need to show my receipt. Curiously he then refused to give me one. :? Can this be right?

Never say never. Several of the cameras I own now were impossible dreams a few years back but they all eventually crashed far enough in price for me to pick them up. I predict I'll be getting a 645D in around 2022 at this rate... :D

Found a 1981 book on medium format
I have an old book on MF written by Michael Freeman. It's quite informative and has excellent descriptions of many systems that were available back in the day.

Black and White Photography magazine
This magazine has an excellent review of the 645D. Many positive things, a few negative ones, three of which were (a) no live view (b) no SR and (c) the one we all have, the reviewer couldn't afford it although he would really like one. :( All the reviews I have seen of the 645D have been very p...

I'm in trouble..
I just put a random bid on a pentax 645n on the site of evil (eb**) and won... Now I need to both find a suitable lens at a good price and explain to the ever loving wife about the saving I made on the bid :) I almost bought a 645N-II a few years back. It just felt right in my hand and the viewfinde...

Pentax 645D at Focus
When I went to Focus yesterday, the first stand I went to was the Pentax Stand (of course), and apart from bumping into DLT, I had a play with the 645D. Well, apart from the standard size of a MF camera, it was not that heavy with the 55mm lens on the front. In fact I would say it is lighter than...
