Compact camera suggestion (preferably APS-C/m43)

As I mentioned, I already have Coolpix-A which is exactly the same specs as Ricoh GR but I am looking beyond a fixed lens.

yes, thanks, looks like a good option but bigger than I'd have liked

Compact camera suggestion (preferably APS-C/m43)

Well, maybe I should have elaborated, what I meant was that the difference is not worth enough to carry an extra camera. For example, I could definitely see the clear difference between RX100 and CPA IQ but the difference is not so great between iPhone/RX100, at least to my expectations. I then sold RX100 and never felt like getting it back. I rarely shoot video (or 4k video) and not an important consideration.

For serious photography, I have other cameras like A7R3/Sigma Merrills but I have been rarely using them nowadays. Instead, I got addicted to Coolpix-A, amazing IQ, and great form factor. The nest part is that it is only slightly larger than RX100, which allows me to carry it anywhere. However as mentioned, the fixed focal length is limiting sometimes, and hence started hunting for a camera in a similar form factor but with zoom.

Folks, any suggestions for a compact camera with a large sensor (APS-C/m43) and zoom.

I had RX-100V briefly which has a nice IQ but I don't see much difference from the iPhone IQ. I also have Coolpix-A (similar to Ricoh GR) but it has a fixed lens which is limiting sometimes.

I am thinking to pick up Sony A5100 but the kit 16-50 zoom seems to be poor (from all reviews I read).

Just wondering, any other options or opinion. I am okay with the LCD-only option too (without EVF).

Thanks

You are quite prompt in sending this reminder and showing notification on the site.

However, you didn't send me a single reminder before removing my status as Pentaxian. I only came to know about the day's limit when I posted in the forum and then I was asked to pay to get the status back.

Disappointed (and disgusted) with such a double standard, especially when I am a member of the forum for over a decade!

Pentax K5 (and Oly EM-5) to Sony A7?

You are ignoring the math - refer my previous post. It is technically NOT possible to have k-5 file with less info to have less artifacts than A7/a7r files having more info but I'll be happy to learn if you can prove it technically.

Again, the following is a simple calculation

K5 - 16MP*14 = 224 lossless Mbits
A7 - 24MP*11 + 24MP*3 = 264 lossless Mbits + 72Mbits lossy bits
A7r - 36MP*11 + 36MP*3 = 396 lossless Mbits + 108Mbits lossy bits

It is a fact that A7/a7r lossy compression having artifacts in some cases but it's worse only when compared against comparable cameras (FF, 24MP and above) but not against k-5.

Pentax K5 (and Oly EM-5) to Sony A7?
Posted By yusuf

A7/A7R lossy compression is well debated and I am aware of that. My point was that does it make it worse than K-5?

A7 and A7R files, even with their lossy compression, carry more lossless data than K-5. Lossless data in K-5 will be 16x14bit, while it will be 24x11 for A7 and 36x11 for A7r, not to forget there are still more not-so-lossy data there. Also, the larger pixel and resolution will results in a less quantization error. So I doubt K-5 can perform better than A7/A7r despite later having lossy compression but would be interesting to see otherwise.

Being a previous K-5 owner, I certainly find A7/A7r files treat to eyes.

It would be interesting to see visible evidence that A7x lossy compression files perform inferior to K-5. that's what OP is comparing.

A7 is a nice camera and a huge update from K5 (except IBIS). It's so cheap now that you should go for it. EVF is awesome for manual focus and eye focus is brilliant (for the price). Obviously, AF is not as good as the new Sony camera but still better than K5.

It is also one of the lightest FF camera (all the new Sony cameras with IBIS are at least 200gms heavier). I now moved to A7RIII but I kept original A7r because it feels so light compared to A7RIII.

Samyang 14mm is good, provided you get a good copy! Can be used with full frame too if you upgrade later.

I noticed that my ranking has changed from Pentaxian to Veteran member. Also, the market place access is blocked.

Just wondering what is this new ranking?

Nikon Coolpix Model Q10125
Posted By yusuf

Any idea what it is?

Today I bought a "Coolpix A" camera from a local classified. Although the camera appears to be working fine, images show "Nikon Corporation Q10125" as the model number in EXIF instead of "Coolpix A". Any idea what is Q10125?

Also noticed a few other things:
  • The serial number on the bottom is not the regular Nikon serial number but starts with "PT"

  • It is running firmware version C0.014 which appears to be quite old. I tried to update the firmware after downloading latest Coolpix A firmware from the Nikon website. However, the camera is not recognizing the new firmware on the SD card and doesn't give Update option. This may be due to model number mismatch.


Any idea?

Samyang is a beautiful lens. M85 is small but has bad CA and also prone to element separation. See if you can get hold of K85, much smaller than Samyang, and reasonably well controlled CA, sharp, though not 1.4.

well, arguable but what to say :) isn't it unfair that only one sided talk about praising of OVF and DSLR allowed? In such circumstances, no discussion can take place - you find EVF unpleasant, I find OVF obsolete, difference of opinion but that's what the platform is for. I didn't make any personal remarks, but then my post is reported to mods and deleted which only had comparison (funny that someone finding technical comparison offending). So I am done with this topic.

It's not about what I love, it's about what helps me make better pictures. Like many of you, I loved OVF for over 25 years but when I found a better alternative, I moved.



well, that's a very old argument for old EVF, you certainly didn't see how amazing A7r2/A9 EVF is, have you? And people don't realize that if scene in EVF clips, likely will clip in final output too - so you get feedback right on time instead getting surprises later. Photographers eye better get used to what the final output would be instead of what it is perceived by OVF. And of course, EVF helps Photographers eye much better with right focus, DoF preview , focus magnification. Regarding lag, agree but it's not even noticeable for general photography, maybe for sports photographer or panning which I am not into. And for a bit of disadvantage, I can't ignore the advantages EVF offers over OVF.

so? do I have to praise DSLR, just because it's in DSLR forum? Would love to see if you come up with logical arguments to stay on topics then getting personal.

what I said is that using SLR design in DSLR was a stop gap arrangement, please do not twist my words.



Can your optical TTL viewer do?
- Focus magnification
- Focus peaking
- live histogram
- view in dark (low light)

Attempt by Sony is not boresome, it's just awesome.
