Pentax 67 135mm f/4 lens on 645N

[celasun]

<p>I will be using a Pentax 67 135mm f/4 lens on my 645N camera.<br>

Is there anything I should be aware of like exposure compensation?</p>

<p>Only that it will be manual-focus only, that the adapter may cost more than the lens, and that it will surely leave you with a burning desire to add a 67 to your camera collection. :-)<br>

I use a 165mm f/2.8 on my 645N and - focussing aside - it works just like any other lens.</p>

<p>You should be fine. The exposure should all be done for you in Av mode. If you use extension tubes though, you might need to use stop down metering. And yes, you will most probably come away looking for a 67 ;)</p>

<p>Thank you both, my friends.<br>

You are right; I am looking for a nicely used 67ii. Not that I cannot find one; I just need some... some... "time" to justify the purchase ;)</p>
