Hey Vic, I'm guessing you should be back by now. How was the trip? Any nice photos to show?

Shooting Bears
Yes I'm back and yes I got some good shots. I've yet to edit them though. As the weather is so good in the UK just now my wife has me slaving away in the garden and I've also started my part time summer job in the local theme park. I will get round to editing them and post some on the forum just giv...

Small business accounting software (off topic)
Completely off topic, sorry, but it seems that there are number of members who are self employed or who are retired having been self employed. My son's just starting his own business (sole trader, no employees) and I'm stuck with all the paperwork and finance having been a finance manager in the ...

What is your technique to focus M lenses?
I am struggling to get sharp photographs using manual Helios lens. I turn the focusing ring and rely on AF indicator to beep when the picture gets in focus. It does beep, I take a photograph and the success rate is very low. What is your technique? PS - I did check BF/FF and it is as good as it c...

What is your technique to focus M lenses?
I rarely have a problem focusing M lenses, but don't have any Helios lenses. Bear in mind that the beep and red square isn't the focus confirmation, at least with my K-r. The green hexagon is the focus confirmation. They are always pretty close, but it might be enough if you are relying on the be...

What is your technique to focus M lenses?
I used to have problems, but once you find the best way to get reliable focus it soon becomes second nature. If you are using the cameras af to alert you, then it is worth finding out if it is more accurate focusing to or from infinity, as the indication can cover a degree of focus ring rotation, an...

What is your technique to focus M lenses?
Hi Pietrach I don't have the lens you do but as mentioned above it is best to wait for the green hexagon as that is focus confirmation. With my m42 preset lens I open the apeture to aid focus then stop down to take the picture. With my m42 'auto' lens I switch to a which leaves the apetur...

The other thing I forgot to mention it's worth having a play with 'catch in focus' if you have it (not sure which camera you have). It's not always appropriate, but will certainly help with moving objects. I sometimes use it for macro as well.

What is your technique to focus M lenses?
All good advice above, but you must make sure the dioptre is set for your eyes and that the grid in the viewfinder is sharp. If this is set wrong you have almost no chance of accurately focussing. Another technique that is almost foolproof is to use the Live View feature on the LCD screen and zo...

What is your technique to focus M lenses?
Just to emphasise what Trickletreat said above as this was the biggest issue I found when I started using MF lenses : Focus Confirmation = you can see this in your VF - it is the little green hexagon. When lit it shows you that the subject is in focus. Note however that there is a 'range' (also w...

What is your technique to focus M lenses?
Provided the dioptre correction has been done correctly, the focus ring is turned until the image looks sharpest in the viewfinder. What's interesting is that what was once perfectly normal technique, using our eyes, seems to have become an issue where we look to the camera to tell us instead. ...

What is your technique to focus M lenses?
1. The viewfinder on APSC cameras is quite small, and with no split screen, quite difficult to check critical focus with. (OK if you habitually stop your lenses down, as I suspect John does, as the dof masks focussing error). 2. The green hexagon light has a margin of error. Turn your focus ring ...

What is your technique to focus M lenses?
Focusing error in very real, as has been demonstrated in the past many times, and I wouldn't want to diminish the difficulty that many people have with it. It seems to depend very much on our eyesight. I know for example that my dad had dreadful problems focusing his Nikons, despite being a preci...

What is your technique to focus M lenses?
I would far rather use the screen on my K7, or purchase a K01 (which is even better as it has focus peaking) than resort to an expensive rangefinder system (with limited lenses to choose from). Live view is always 100% accurate as you are seeing 'what the sensor is seeing'. Hopefully Pentax will...

What is your technique to focus M lenses?
Yes indeed, the K-01 is another lateral thinking solution, far better for Live View than the DSLRs. In the context of the M series lenses a better solution perhaps. The other possibility is the Q with the new K mount adapter, when that becomes available. Third party adapters are already freely...

What is your technique to focus M lenses?
As my main job is TV Cameraman, finding best focus manually, very fast, is second nature. I wondered if stills might be trickier but it isn't. It's a directly transferrable skill. It's an instinct you develop through practice. I'd echo John's comment about people becoming reliant upon technology. If...

What is your technique to focus M lenses?
AnthonyB has also hit on another important reason why I tended not to buy third party lenses. Pentax, Nikon and Bronica all focus the same way. Everyone else focuses in the opposite direction. This doesn't matter so much when using AF, but it does cause a monent's delay when using MF and is defin...

Agreed, my Pentikon system works really well together. Best regards
