Great source of information for the continued enjoyment and use of four thirds lenses. Any suggestions to get the most out of my CDAF optimized 14-54 II lens on the EM-10 II?

I am enjoying the near macro capabilities and good IQ but find the slow AF a bit cumbersome. I have single point focus in the center and use Eye detection as well. Any suggested changes to settings to optimize AF?
I’ll reply to my own post. After buying a second hand E-M1 and MMF-3 adapter, the CDAF optimized 14-54 II worked markedly better in autofocus speed. Enough so that when I decided the E-M10 II was a better fit for my needs and sold off the E-M1, so went the 4/3 lens and adapter. While others soldier on with other bodies, I could not imagine continuing to use a non-PDAF sensor equipped body. I really liked the 14-54 rendering and see tremendous value in the 4/3 lineup but would suggest clear expectations for use with anything other than an E-M1.

I appreciate others looking into the 70-300zd focus status. If I need to focus manually other bargains are more tempting, but it's still a fun lens. Even handheld on a GX1 the results are quite nice. Maybe an em1 body will show up to justify it.. :rolleyes-38:
:flypig:


P.S. In case you missed it elsewhere: problem solved. Yes its been a while since I used a lens (in any mount) with an AF/MF switch. :blush:

I hope that the E-M5 III (when it finally comes down a bit price) will help give these lenses a new lease on life. I haven't seen any uptick in 4/3 lens prices yet on eBay etc. The fact that one can get an E-M1, adapter, 12-60/2.8-4.0 and 50-200/2.8-3.5 for under $1000 is really amazing.

(While it is a little worrying that none of the lenses are repaired any more by Olympus, I've never paid less than $250 for a lens repair, so given that many of these lenses are <$300 it's not really that different from getting any other unwarrantied lens)

Though as I've said before, the E-m1 mark I not having cross shaped PDAF sensors really limits its focusing ability in low contrast scenes.

I bought the E-m1 mark I 4 years ago specifically because it was cheaper than the micro 4/3rds Olympus 40-150mm f/2.8 lens, and it would allow me to use my existing classic 4/3rds Olympus 50-200mm f/2.8-3.5 mark I (non-SWD) lens. For a lot of settings, it works. However, I found when I took it out on a whale watch, that the combination hunted badly and could not achieve a focus lock. So I gave up trying to use the 50-200mm lens, and went to the micro 4/3rds Olympus 14-150mm mark II f/3.5-5.6 lens which worked perfectly. The next year, I took the E-5 instead of the E-m1, and using the 50-200mm lens, it achieved a focus lock immediately (E-5 has cross shaped sensors). The cross shaped sensors allows the camera to find straight lines in either orientation.

In addition, I believe the E-m1 mark I only uses the PDAF sensors for the classic 4/3rds lenses and not for the micro 4/3rds lenses. I'm not sure whether it is in S-AF or C-AF modes that it doesn't use the sensors for the micro 4/3rds lenses. So, IMHO, the E-m1 mark I is better than the other micro 4/3rds bodies for classic 4/3rds lens support if it can achieve a focus lock, but it is limited IMHO.

This is evidently fixed in the E-m1 mark II, which now has cross shaped sensors and presumably it is also in the E-m1x and E-m5 mark III cameras. I believe starting with the E-m1 mark II, it now uses the PDAF sensors more for the micro 4/3rds lenses.

In addition, if you are buying the E-m1 mark I used, you need to make sure the copy you get doesn't suffer from one of the classic E-m1 mark I complaints:
  • Green blotches on the EVF caused by exposure to the sun, particularly if you set the diopter high;
  • Strap lug nuts coming out; (and)
  • Mode dial that stops working.

4. Four-Thirds.org (official consortium for FT & MFT members; note they don't normally include non-members making MF lenses such as Voightlander and Zhongyi Mitakon):
Four Thirds | Four Thirds | Four Thirds | Chart(Lenses)
Four Thirds | Four Thirds | Products(Lenses)
Just a random observation, but today I went to look something up on the old 4/3rds list of lenses at four-thirds.org and found that all the 4/3rds Panasonic lenses have been removed. Granted I think there was only four total, but the micro side still lists all the Panasonic lenses. I wonder why all the 4/3rds Panasonics have disappeared?
