Pentax 645n Vs Canon EOS 10D
Hi, I am a former studio pro shooter, I shot mainly advertising work on large & medium format and the digital V film debate I find amusing....there is lots of nonsense talked and lots on mis-information...this is my view for what it is worth. 1. Resolution & pixel count is quoted regular...

Just got a 6x7 11 , well pleased
I just got one this month on ebay to from a guy in sweden arrived here in the UK in 3 days. Took it to China for 2 weeks and loved it the results are amazing with provia and velvia, was a little under on average exposure so might make it half a stop over next time. Found the best way to use it was...

645N Manual
I'm looking for a 645N User Manual, anyone? When I bought my Canon flash manual recently, Canon charged me £8 for a photocopy, shocking. Hope this is not the case with Pentax. Delighted to be back with the make that gave me the best results over the years. Went from P30N to Eos300 to EOS1V and stopp...

Polarizer for 645
Linear will be just fine on a manual focus. Sorry for the slow reply, but I do not usually frequent this board as it only makes me want to go blow several hundred dollars on a 645.

67 Lenses on 645 using adapter?
Tried the shift lens at the weekend whilst in London - gutted that it's not that wide at all... 75mm on the 645 is only equiv to 50mm in 35mm. Just need to wait for the slides to find their way back to me and I'll post some results.

67 Lenses on 645 using adapter?
Got the results back from my first try with the 67 75mm Shift on my 645 - definately some lessons learnt. I understood that at full shift I would need to increase the exposure to compensate for the light fall off - the instructions stated that this should have been around an extra 1 to 1.5 stops. Se...

67 Lenses on 645 using adapter?
I've been using my 28mm 3.5 shift (on 35mm of course) for over 20 years so here are some observations: Spirit levels are almost essential, I use a Manfrotto head with 2 built in Also essential is a grid focusing screen, as soon as you shift microprisms etc turn solid black and the lines on the...

67 Lenses on 645 using adapter?
That's really useful info, I don't have a grid screen and although the screen on the 645 does go dark it is bright enough to just about see what I'm up to even with full shift applied. Using spirit levels is exactly what I've been doing to get the camera spot on level on both planes. I use the tr...

67 Lenses on 645 using adapter?
hello all. here are my informations. 1. i have read that using the 67-645-adapter would decrease image-quality. why? there is no optical element. i have heard that there a especially good 645-lenses. so eventually if compared to not so good 67-lenses. e.g. zeiss told us that hasselblad-lenses have ...

67 Lenses on 645 using adapter?
you can be sure that we will compare 80mm /85mm zeiss against pentax-equivalents at the relevant subject to camera-position. subject having the same size on film. i would even go further and use p67-cam with vaccumback and contax 645(vaccum) and contax rts III(vacuum) and compare with pentax 35mm...

Loading Film in 67II
You wind the film until the arrows line up, be it in mid-stroke or whatever, and then close the back. The mechanism will then sort out the rest.

645 multiple shots problem
I have a Pentax 645 which seems to have a problem with being able to take multiple shots. It will take a picture and advance the film, but I must turn the power off and then on via the rocker switch before I can take a second picture. I have replaced both the AA batteries in the hand grip and the li...

Measuring light on snow with Pentax 67
When using my Penatx MZ50 35mm for the first time in snow conditions, ie a couple of portrait shots of friends with a total white out snow back ground (and very sunny conditions) I just used the EV, I overexposed at 0.5,1.0 and 1.5. and took a couple of shots at each level. I found that 1.0 was g...

pentax 6x7 banned?
What it's all about is the RoHS directive, (That's the Restriction of Hazardous Substances directive.) aimed at resticting the use of lead and other materials in electronic equipment. I have worked in electronics for quite some time now, and there are a whole raft of directives that have been int...

pentax 6x7 banned?
Me back again. I have to say that from the manufacturing point of view there is little, if any extra cost in complying with RoHS. After all, the directive will apply to all products sold in the EU. So they will have to re-tool for lead free solder, (already used by many manufacturers) and source ...

Pentax 67 - metering head or light meter?
Hi all I have a battered 67 with a broken metering head - aside from that everything works despite looking like it was used to hammer in nails. After unsuccessful attempts to meter with a 35mm SLR, I'm borrowing a light meter from a friend but that will have to go back at some point. Is it ...

Multiple exposures using 6x7
Hi Does anyone know how to do multiple exposures on the mirror lock up version of the 6x7? Someone suggested you need that key that looks like a plectrum however I thought that was just to fire it while the back is open. Any help would be appreciated. Thanks

67 repairs
Do you not have a ttl head on your 6x7? If you do then I would just go by the meter in the camera. In case you dont I would assume you would need to apply bellows extention factor that applies to large format....the principle is the same. From what I remember it is something like (V/F)2 V...
