Yeah I get that, I was just trying to give some perspective of cost as the two lenses aren’t equal. Don’t get me wrong 600mm f4 lens prices are eye watering but it’s not ‘fair’ to compare the price against a 300mm f4 as they aren’t the same. I would hazard a guess if Sony made a 300mm f4 it would be a similar size and weight, and a similar cost to the Olympus
Unless I've been missing something for the past 60 years or so, f4 on any two lenses lets through the same amount of light, regardless of focal length. Hence, a half frame 300mm f4 puts the same effective amount of light on the sensor as a full frame 600mm f4 would. So far as depth of field goes, allowing for the chosen circle of confusion, a 300mm will make available the same depth of field on a half frame camera as on a full frame camera.
Whilst f4 lenses let the same amount of light in the surface area of the FF sensor is 4 times larger so effectively 2 stops of light, therefore a full frame sensor at f8 will gather the same total light as f4 on m4/3. I believe this is part of the reason FF sensors produce less noise.
I agree with @snerkler, you're not getting this. Light capture wise, perhaps, but not in depth of field, which is key.
A very sophisticated argument but specious in this context..
This is a valid description of depth of field and its relationship to focal length and aperture.
It's not an arguement, it's a discussion
In terms of exposure yeah the f4 will allow for a higher shutter speed or lower ISO, however I could shoot at 300mm f4 1/1000 ISO 200 on Olympus and 600mm f8 1/1000 and ISO 800 on FF and get pretty much the same shot.
I would suggest a used A6600, has ibis and a much much much better battery, the 70-350mm is a great lens and a very compact combo for wildlife.
I guess it all comes down to where you set your goal posts. I would suggest the combo can give very good results, especially in good light.
I will hopefully finalise my decision today toby , the current weather in north wales hasn’t as yet allowed for a proper assessment of what I have at the moment and obviously money is not unlimited as well
Is there a reason you're not considering the Olympus 75-300mm or Panny 100-300mm instead of the Sony 70-350mm as both would give 75mm extra reach?
had both of them in the past and already got olympus om1/300mm f4 /50-200/plus a few others and t.c's ,this is basically a backup system for the wife to use or just for a change when the fancy takes me .. so far quiet impressed with the a6000 body and 55-210 so thought I would build on it ,but it now looks like the 6600 I was viewing is gone anyway . so will hold fire for a bit no rush with current weather conditions
I have an A6000 as my 'travel' camera - to keep it small and light I just have the 2 kit lens (16-55, 55-210) and the 35 and 50 f/1.8 OSS primes.
just been out and took a few test shots , most at 1600iso and after cropping in i'm finding them extremely soft ,so is the answer a newer body with hopefully improved sensor or a longer better grade lens at the moment restricted to 6000+55-210 .should I sell that combo and upgrade or just forget it expected better iq in all honesty
The 55-210 is the basic APS-C kit lens - it needs good light, ideally stopped down a touch, and will show it's weaknesses if you over crop.
I guess part of it depends on why it's soft, is it missing focus, cropped too heavily, too much noise and/or NR or a combination? Usually the lens makes much more of a difference in IQ vs a newer version of the sensor.
),
I borrowed one of those, and I'd agree with that assessment.
How’d you get on with the 10-20mm PZ? I have it for my A7RV, optically it’s very good but I’m not a fan of the electric zoom but I can’t find a good alternative that’s a similar size and weight and as good optically.My little A6700 kit grew big quickly (a bit too quickly really
This is now my travel setup, and I love it. It all goes into a Bellroy Venture Sling 9L cross body bag.
That the A6700 Body
The 18-135 G F3.5-5.6 (which quite frankly is way sharper than it has any right to be - just wish it started at 16mm (24mm Equivalent) rather than 18mm)
The 10-20 G F4 PZ
The 15mm G F1.4
A dual USB Charger
The Sony GP-VPT2BT Bluetooth Tripod and grip
Not shown the amazing Sony ECM-M1 Microphone for the cameras MI shoe (so cable less).
Thanks. First time I've been called Trevor though
Used 100-400mm with 1.4x TC? Similar weight to the Olympus 300mm f4
Price though can’t stretch my pension that far, didn’t think you can use a tc on e.mount crop bodies ?
I don't think there's any issue using Sony TC's on APS-C, AFAIK it's just third party TC's you can't use on any Sony mirrorless.
Very interested to hear how you get on with the 70-350 on your A6700 (assuming you will get it) - I'm still dithering over whether to upgrade(?) from my RX10iv to that combination but can't quite convince myself as yet...
Your in the same boat as me Mike you would be coming from 600mm reach to 500 ,mines from 840 to 500 . But if the tc works ?? On a 70-350 it pushes the boundaries . Never used the rx10 so don’t know about the a.f but this eye tracking on the a6700 is insane it grabs instantly and sticks like glue
I think the TCs are compatible with the A6700, but not the 70-350 lens. There's only a select few lenses that are - effectively white lenses only I think
Yep just checked not compatible, will only work on the 100-400 white lens, saying that Olympus are the same t.c use limited
