Perhaps it's understandable that they don't back-port features into old models

You will need to tell the camera the focal length, but it's not necessary to use the green button in Av mode. You only need to do that on K-mount lenses in M mode.
All the green button does is stop an M or K lens down momentarily and take a meter reading. That's because as you select different f stops on an M or K lens, the aperture actually remains open until you take a shot.
There's no need with an M42 lens; it will be stopped down anyway so aperture priority will work. If after focusing you return the aperture to the 'stopped down' position, the camera will meter in Av mode in real time.

Yep and as it's a firmware/software feature, there's no excuse for leaving it out! Tell that to Canikon though...Pentaxophile wrote:
According to the other forum, yes it does!! Allows you to do it individually as well as globally.
I've never buy a DSLR that didn't have AF fine tune per lens Omission of such a feature is stupid given how far out lenses can be.According to the other forum, yes it does!! Allows you to do it individually as well as globally.

I'm a huge fan of the Tamron 17-50 f2.8. Not too big, quick to focus and so sharp you might cut yourself on its images! Oh, and it's cheap compared to most of the alternatives.

Hi Peter
There are a couple of things that need to be checked with a K-r to shoot with manual lenses. Forgive me if you have already done any of these.
Firstly you need you need to set 'use aperture ring' to 'permitted' in order to use manual lenses.
Press the menu button.
Press the left button on the four-way controller once to get to the Custom Settings menu
Press the down button on the four-way controller and select Using Aperture Ring
Press the down button on the four-way controller, select Permitted and press the OK button.
Press the Menu button to exit the Custom Settings menu
You need to set the focal length of the lens when you turn the camera on, though this isn't vital if not accurate though the EXIF will be wrong.
With M lenses (no A on the aperture ring) you simply set the aperture ring to the desired setting. Select manual (M) on the dial on the camera.
When you have composed the shot press the green button once. This will take a reading for you and set the shutter speed to match your chosen aperture. I tend to find that this underexposes a little so usually reduce the selected shutter speed by a couple of steps.
A lenses can be set to A on the aperture ring and then you should be able to use AV mode to select both aperture and shutter speed.
Hope this helps
Chris
If using an M42 adapter, the lens will work in Av mode - the aperture will not be held open at all (resulting in a darkened viewfinder as you stop down). This is different from using a K-mount lens so none of those settings are necessary.Hi Peter

The published dimensions are:
Height: 17 cm
Width: 24 cm
Depth: 14 cm
Will double check when my partner's woken up (it's in storage under the bed!)
When looking for an outer bag to fit this into, I found it would happily go into something slightly smaller - there is a small gap between the foam sheets (look at the corner of the bag in the picture) which means that it can squeeze into a smaller space without crumpling up.

That's interesting Charlotte - that's a cheap lens compared to all the others! The 'plastic fantastic' Cosina version is probably the cheapest genuine macro out there. I had one (MF version) and I did like it (got stolen).

Maria, you can use the aperture ring in Manual and use the green button to set (roughly) the correct shutter speed. You need to make a couple of changes in the menu, but this only has to be done once:
USING M or K LENSES:
In the 'custom' menu:
'Using aperture ring' - set to 'permitted'.
'Green button in manual' - set to 'Tv Shift'.

'Green button in manual' - set to 'Tv Shift'.

Designed to fit a bicycle panier, this nylon padded bag insert has comartments for a DSLR plus two lenses (adjustable velcro dividers, also padded). Fits one of those cheap blue canvas army bags from Yeomans perfectly, or could be used within a custom bag. Photos are from the web; actual photos to follow.
