Originally posted by Rondec There is a narrative going on here that is a little problematic.
(1) The main reason to purchase an MILC is simply that old mounts are being abandoned. This is true across the board. What remains unstated in the article is that the main reason why the old mounts were abandoned was because brands hoped to convince photographers to buy new (more expensive) lenses for the new mounts. Yes, you can use your old lenses, but they use adapters and often features are somewhat crippled with those adapters. I'm a bit cynical when I think about corporations "doing what's best for their consumers."
(2) SLRs have come a long way. It may be that SLRS do not have auto focus points to the extreme edge except in live view or that they don't have as much information in the viewfinder, but they are pretty capable. The K-3 III can do 12 fps and does pretty well at AF-C -- there were SLRs that were better at tracking than the K-3 III. Most people simply don't need a million auto focus points or 20 fps.
(3) There is a price to pay for MILC technology. The price is primarily paid in shorter battery life and artifacts that have to be masked from the PDAF points. These are seldom mentioned in reviews, but are really there. Many MILCs have struggled with astro photography in the past due to aggressive noise reduction algorithms with long exposures.
(4) Most people's images look exactly the same regardless of whether they are using MILC or SLR technology. The limitations are not due to the presence of a histogram in the viewfinder or too few auto focus points, but rather what lies a few inches behind the viewfinder.
1. Same-brand adapters generally work quite well, as do pricey third-party adapters. There's a person on DPR and Fred Miranda that shoots wildlife - including BIF - with Canon lenses adapted to his Fuji.
I don't think Canikon specifically moved to MILC in order to get existing users to buy new lenses. You can keep offering new iterations of traditional lenses (such as 24-70/2.8 or 100-400/5.6) as sensor resolution and AF performance increase. That's a formula that worked for many years. The real impetus (IMO) is that Sony MILCs ate Nikon's lunch and were making Canon nervous. That's why Canon and Nikon entered the MILC market so late - they thought DSLR's were
the performance cameras,but Sony's performance in the marketplace proved them wrong.
2. I agree DSLRs have come a long way, but MILC has advanced further, faster. The development curve was accelerated because camera manufacturers moving to MILC were able to start with a clean slate, not having to worry about natively supporting legacy compatibility.
3. Yeah, astro is an area where DSLR's still seem to rule, and Pentax IMO has the best combination of ease of use, features, and image quality. MILC counters, though, with video performance, silent shooting, shutter-shock mitigation, greater variety of bodies with IBIS, and more possibilities for reducing kit size.
4. Totally agree. I realize the article in question was meant to be a surface-level bit of writing and not a deep-dive, but the author really should have mentioned that the image quality from DSLR is just as good as a same-tier MILC, and that DSLR performance is just fine for the majority of photographic needs.
