For head shots with the 150mm f/4 lens you need to use the 18mm extension tube or perhaps the 1.4 X magnifier.

150 x 1.4 = 210mm.... best plan is the 18mm extension tube.

Excellent points about depth of field with 6x7 format. Consider the 35mm camera using 85mm f/1.8 for subject isolation in portraits, the 6x7 portrait lens is often a 150mm f/4. Note that Bronica GS-1 was built to be a lighter 6x7 than Pentax and Mamiya. All lenses are leaf with maximum speed of 1/500 and the lenses are slower f stop which keeps the

lenses lighter and smaller. Fastest lenses are 80mm f/3.5 and 100mm f/3.5. The 150mm is equivalent to 75mm and the 200mm is equivalent to 100mm neither is particularly close focusing thus an 18mm extension tube is used for close headshots.

<p>It may be that those Mamiya Z series lenses are of good quality and are orphaned by poor camera bodies…. so would they be a good purchase for Mirrorless systems and adapters? I tried the 50mm Macro on a Nikon V1 and was pleased.<br>

<p>I will be moving to Arizona near four-corners. I would like to know the pros and cons of using a Mamiya Cabin 67-Z slide projector with 6x7 slides vs a digital projector with 24 mpx images from a Pentax k3. Landscape photos are the most likely subject.<br>

I have both 6x7 and 645 film cameras. I will need to buy a projector. Any thoughts on the screen image differences?<br>

<p>I have an RF645 which I bought 2nd hand some years ago. The film advance mechanism was a problem on many of these. Things were fine for a while but ..... Eventually on mine the film would not advance. I sent it to Tamron/Bronica service in New York and all is fine now. If you like film this is a really nice camera.</p>

<p>I have a Bronica GS-1 and a Polaroid Film Back G.<br>

Is there any way to use this back with any currently available instant film?<br>

<br />If so what modifications to the film back are needed?</p>

<p>Completely off task here .... but Pentax K-mount and current Pentax in body stabilization means all lenses from Pentax A lens forward have both metering and shake reduction. As to what that will mean in sales volume for the coming in 2016 Pentax Full Frame digital SLR I have no idea. Has Ricoh saved Pentax? Time will tell. Ricoh is now introducing more Full Frame lenses.</p>

<p>The above conversation has me thinking ..... I have a Bronica GS-1 and a Polaroid back attachment. I have never used the Polaroid back. Now I am interested. What film would I use for this Bronica GS-1 6x7 camera's Polaroid Back?</p>

<p>The 645 for the road.....<br>

Look at Bronica rf645 ... the medium format rangefinder. For portraiture the standard lens should be fine. Very compact and easy to carry with good glass.</p>

<p>The GS-1 metered Rotary Prism is often available at a reasonable price on eBay.<br>

There is also a hard to find GS-1 tripod attachment, which rotates the camera from vertical to horizontal.</p>

<p>Great Work Ivan. Very enjoyable photos.<br>

I am a bicyclist who likes to tour and camp. The size of the Nikon 1 system is significantly smaller than HEX etch. when the entire kit is included. For most trips I take the 10-30 & 30-110 zooms and the 18.5<br>

The fast accurate focus, high frame rates, & the occasional video in such a small package are really appealing to me. (I have a Samsung Note II phone for snapshots but as you point out the iPhone is no match for the Nikon 1 system, neither is the Note II).<br>

I would really like a native Nikon 1 70-300 or a 70-200 f2.8 for shooting indoor basketball.<br>

I will be buying the 6.7-13mm zoom for landscapes as I am in Nevada and am surrounded by landscape.<br>

This camera is great fun to use. I've even thought about purchasing the PD Zoom 10-100 for better video now that the prices are a bit lower. (I would not be taking that camping).<br>

Thanks again for the great photos.<br>

<p>What is the learning curve on being able to use and handle the Canon as well as you use your Nikons?<br>

Is this cost of a new body every three years because they wear out or because they become obsolete?<br>

What is the maximum print size you need? How much camera does it take to produce that size?<br>

For my son a D700 with that 24-70mm f2.8 zoom does just fine. The Resolution with a 50mm f1.8 seems pretty similar to 6x7 film.<br>

So do you really need a digital camera that has the resolving power of a 4x5 view camera?<br>

How long will that Nikon D3 last before it wears out?<br>

Seems to me that the next Nikon will likely be better than a 6x7 medium format camera.<br>

How much difference can one see at a 20 in x 16 in print size when a D700 or D3 is compared with a D3x?<br>

Yes there were lots of improvements from D1 to D3 and from D100 to D300 and they were useful. I do not expect to see anywhere near as much in useful gains in picture quality in the next decade.<br>

The camera manufactures are in business to sell cameras ... new may not always be new and improved .. as far as actually improving output quality.<br>

.<br>

I do not live in NZ but I'd vote for sticking with the Nikon for at least 12 months more, if possible.</p>

<p>Spelling on your prices page: "including" rather than includeing. Probably the editor will catch it.<br>

Very nice an impressive site.</p>
