Which lenses are you missing?

[cascadian]

I'm dreaming of a .. light telezoom. A 35-150 that is more like 3.5-4.5, or a mirrorless rework of classic 50-200 or 70-210 designs. I have a K-mount 70-150/4 (from Ricoh no less), 430g and 52mm filters - that would do nicely in an AF wrapper.

Many a day I look at my Pentax lenses and wish they would join the Consortium or Alliance, and just sell lenses. Their new KAF 4 mount finally includes electric aperture control, about 6 years too late

My 40xs and 70 Limited primes will soon be shooting 4:3 on a Lumix L-body! Oh yeah, as noted above - my old Sigma 50/2.8 macro too! :√)

KAF was around in 2016, I'm glad I got rid of Pentax.

? 40XS and D70 are APSC lenses and you can't control the aperture.

Adapting Pentax is a terrible idea.

It's what I have, so it must do until the fun-money fund refills. The 40 and 70 barely vignette in the corners so 4:3 crop should pass my casual tests. I've no doubt many here would not approve!

I have the pk-L ring from KF with fake aperture control, so no data xfer but the photons are unaffected.

I'll soon be adding an Askar 71F flat-field quadruplet telescope to my lens list for astrophotography; it's basically just a funny looking 490mm f/6.9 prime lens.

A modern and as compact as possible 135mm f1.8 is what I'm waiting for.

I add to my old wish list (first 2 spots) 2 lenses. All lenses shall be small and light.

• 28/2.0 FFL
• 70-200/ 3.5-4.5 (or 4.5-5.6 to make it smaller) for travel
• 35-150/4.0 for travel
• 28-100/4.0 for travel

Not on my "urgent" wish list, but still a desire: Especially from Sigma I would hope for a new and significant smaller version of a 70-200/2.8 over the next 5 years.

It's not a matter of 'not approving' as it's not native L-mount , it's because it handicaps the camera and deprived you of the fantastic Lumix optics. You'd be better using a Pentax DSLR which I used for 12 years. The AF on Lumix simply nails it with the Lumix 24-105 f4 and 70-300 f4.5-f5.6. I thoroughly tested the latter against my Pentax F*300 f4.5 prime and it is sharper/more contrasty at 300mm, also lighter, obviously 70-300 and with the fast accurate AF. These are some of the reasons why I said adaptation is a terrible idea.

I do have a K-L dumb adapter, mainly to use my Samyang 14mm f2.8 but it's MF anyway and I only use it for astro landscape so set once and leave.

I still have other Pentax, CZ, Vivitar and other film lenses. I did a K28 f3.5 versus Lumix 24-105 f4 comparison and that's the last time it'll be adapted. I had the DA40 f2.8 Ltd too amongst other Limiteds, your XS version is going to be horrible to MF with dumb aperture lever... It's just not worth doing IMO. There are use cases for swirly bokeh vintage lenses etc. but besides those I see no point from experience.

So I upsized to Lumix FF S5ii from APSC DSLR but downsized 30+ lenses into these two Lumix zooms which are better than all the others.

The best way to buy Lumix lenses are with the combo deals where if you know what you want you will literally save £1000s. I saved around £1000 as opposed to buying an S5ii, 24-105 and 70-300 individually.

After I spent some days with my Leica Q3 43 I have to admit, that I really miss a very sharp 43mm FFL in the L-Mount line. If that Leica 43/2.0 Apo lens in that Q3 is really coming from Panasonic, I hope that we will see something similar from Panasonic too. If not, please Sigma, offer a 43 or 45/2.0 i-series which is sharper than the 45/2.8.

Therefoe I update my wish list and add a ranking. My new "wish list" for the L-Mount lens universum (ranking reflects desire):

1. 43/2.0 (small & compact with an aperture ring, but sharper than the Sigma 45/2.8)
2. 70-200/4.5-5.6 (small & compact for travel)
3. 28/2.0 (small & compact with an aperture ring)
4. 35-150/4.0 (small & compact for travel)
5. 28-100/4.0 (small & compact for travel)
