Are you sure this lens has a manual diaphragm? I believe it rather behaves like Zeiss' Classic series, manual focus but electronically controlled aperture.

I’ve not used any of the Voigtlander RF lenses yet, but my understanding is that despite the contacts and communication with the camera body the aperture is fully manual, as the design is from a rangefinder lens ( where apertures are always manual) as opposed to slr lenses. Personally this doesn’t worry me at all, in fact I like it, because it does away with any focus shift issues, gives correct dof, as well as giving the correct live histogram all the time. Ultimately my migration to mirrorless will be because of the smaller size, ability to have much smaller lenses ( m mount adapted if necessary) but importantly the live histogram makes optimising exposure in challenging conditions whilst on the hoof a real benefit.

A 70-200 f2.0 compatible with teleconverter would be a threat to the 100-300 F2.8 so I assume the it will not be compatible with teleconverter.

A 70-200/2 would likely be around $10K, not really a threat at all.

Exactly like one can do with the 100-300/2.8.

As if they didn't want to sell it!

I really don´t like the F1.8 as a max aperture. I always associate it with entry-level primes or zooms.

What about the 200mm f/1.8L?

Having been on CR for some fifteen years I can say with all confidence that the majority of members will hate this lens !

Still, I’m going to give it a whirl. One good thing about using these manual aperture lenses stopped down is that if you are using the live histogram to judge optimum exposure (and your lens has some degree of shading wide open) you don’t have to keep pressing the dof preview button to see the true (albeit jpeg rendered) histogram.

A 24-70/2 would replace my 28-70/2, for sure.

I’d have to think carefully about a 50/70-150/180mm f/2 lens. After getting the 100-300/2.8, and with the 85/1.2 DS for portraits, I rarely use the 70-200/2.8. When I do, it’s for indoor events where the 100-300/2.8 is inconvenient and I bring the 70-200 as a compact alternative. I suspect I’d pass on an f/2 telezoom.

For me, the 70-xxx with Tc compatibility would be a sure buy. If it doesn't take TC´s I might consider the 70-200mm F2.8 Z. Atm, I don't need the 24-70mm f2 because I have the RF 50mm F1.4 VCM which I absolutely love and a standard f4 zoom. I eventually would/ will get the 24-70mm and I´ll probably sell of the 50mm and the standard (I wouldn´t mind). But that purchase can really wait for several years because the 50mm is really up to all tasks right now.

At the same time, when exchanging my f4 zooms for f2 zooms, I would want to get something very light for hikes. I've got the 16mm F2.8 already and the RF 28mm will one day end up in my bag for sure. At one point, I might get the 100.400mm again. I gave/ sold mine to my father in law, I can burrow it whenever I need it. But I'd still like my own copy somehow... The RF 24-105mm F4-7.1. is also on my mind because it is very versatile, but I don't know about IQ.

This plan really will cost a lot and it'll take quite a while to come to fruition for me. But it is a plan worth saving for and selling some other gear, if canon comes up with two great offerings.

TDP updated the review (06/20) with more info about image quality.

TDP review RF 20-50mm f/4L IS USM

Compared to RF 14-35 and RF 10-20 @20 this RF 20-50 shows less contrast especially in the mid-frame and periphery. Also sharpness is less in the mid-frame and periphery. All at f/4.
It performs better in the mid-frame and periphery compared to RF 24-105 @ 24, 35 and 50mm

A 70-180/200mm F2 which takes TC´s would also be a threat to Sony because their lens doesn't take TC´s.

Awesome world's first and hopefully Canon can make it a bit lighter than the very similar spec RF 100-300mm f/2.8 and would be great to have a built in 1.4x extender for 98-280mm f/2.5

Click to expand...

I really don´t like the F1.8 as a max aperture. I always associate it with entry-level primes or zooms. In addition, I am a fan of apertures with full stops such as a f2-2.8 zoom. Worst in this regard is the RF 100-500mm with its 4.5-7.1. I´d really prefer a 4-5.6 or even F4-8

So, either make it 70-200mm F2 or a F1.4 please

Yeah, I am weird sometimes

True

Love it. Will buy it if the R8 2 is retro enough to warrent it.

The optical design reminds me a lot of the EF 50/1.2L. Gaussian. Has character and should give nice bokeh, considering its relatively short focal length.

21 June 2011 was relatively cool and cloudy – good conditions for taking photographs of Onychogomphus forcipatus.

As I don’t have any recent photos, here’s a Southern Hawker, photographed in August 2020.

I'm a complete novice at this stuff and when we were last back in Scotland (I've lived in Oz since 1988) when my Mum passed away we stayed overnight at Tarbert (nice small fishing village about 1 hour drive from Loch Lomond) to get away from things for a break. My wife was shopping one morning so I decided to go for a walk (bugger going shopping) and just above the town was the ruins of the local castle.

First photo is the original photo, and 2nd is after tweaking in DXO Photolab / Nik Collections (yes, some may say cheating but first time I've ever turned a photo into B&W). No particular reason for using the 28-70 f2 for this shot other than the fact it happened to be on my camera at the time I went for a walk.

PS - didn't know which place to post this, so also duplicated post in the 28-70 f2 thread, mods can delete either if in the wrong place.

Ordinary Filmmaker saying the RF 400 f2.8 and 600 f4.0 are definitely coming with TC incorporated, to be announced probably this October and come out later in 2027.

Very nice

Great Banded Grayling - Brintesia circe
Today they flew around me in pairs, in fours, they landed on my hat, even on my lens, on my t-shirt, but they never sat down so I could take a picture of them.. this is the only somewhat successful shot. I became the victim of a butterfly prank.
